Lisovanie za tepla (HIP) je pokročilá technológia pre výrobu plne hutných keramických materiálov, ktoré majú množstvo štruktúrnych (napr. rezné nástroje), biologických (napr. implantáty hutných kostí a kĺbov) alebo funkčných (napr. transparentné štíty a okná) aplikácií. Pre úspešné použitie tejto technológie je potrebné, aby predspekané vzorky boli plynotesné, teda bez otvorených pórov. Výskum zaoberajúci sa premenou otvorených pórov na uzatvorené je preto veľmi dôležitý, avšak iba málo publikovaný v odbornej literatúre. Preto bolo experimentálne a teoretické štúdium tohto javu hlavným cieľom diplomovej práce. Analýzy teoretických modelov ukazujú, že transformácia z otvorenej na uzatvorenú pórovitosť je materiálová charakteristika, ktoré sa mení iba s dihedrálnym uhlom, nezávisle na veľkosti častíc prášku alebo na spôsobe tvarovania a nastáva od 92.6% t.d. do 93.7% t.d pre daný materiál (oxid hlinitý, oxid zirkoničitý a horečnato-hlinitý spinel). Tieto teoretické výpočty boli porovnané s experimentálnymi dátami z literatúry a dátami z experimentálnej časti diplomovej práce s úspešnou zhodou pre kubické systémy (spinel a kubický oxid zirkoničitý). Výsledky experimentov s oxidom hlinitým boli v dobrej zhode s experimentálnymi dátami publikovanými v literatúre, ale boli vyššie ako teoretické hodnoty. Na objasnenie týchto odlišností bolo vytvorených niekoľko hypotéz a tiež boli navrhnuté spôsoby riešenia tejto témy.

Alumina based transparent ceramic bodies were prepared within this diploma thesis by the gel casting process followed by presintering to closed porosity stage with subsequent hot isostatic pressing. The problematic drying of large bodies was solved by means of careful temperature and relative humidity control and by osmotic drying. Almost perfectly dense ceramics were achieved thanks to colloidal processing of TM-DAR and TM-UF ceramic powders providing a final structure with grain size of 381 nm, resp. 302 nm. High real in-line transmission of 72,3 % was achieved at wavelength of 632,8 nm and thickness of 0,8 mm. Among mechanical properties high values of hardness HV10 = 22,5 GPa, fracture toughness KIC = 3,99 MPam0,5, Young’s modulus E = 400 GPa a bending strength o = 494 MPa were achieved.

In the doctoral thesis, the bi-layer ceramic bodies with core-shell geometry were prepared by thermoplastic co-extrusion method and for these composite bodies the mechanical properties were studied. For study of co-extrusion and mechanical properties were designed two composite systems. First system ZTA-A combined the dense core ZTA (zirconia-toughened alumina) and the dense shell Al2O3. Second system ZST-Z consisted of porous core and dense shell made from ZrO2 for both cases. In the thesis, the rheology of ceramic thermoplastic suspensions and their mutual influence during co-extrusion was studied. Subsequently, the debinding process and sintering were studied, and based on the optimization of all process steps were obtained defect-free bodies with core-shell geometry. The mechanical properties (elastic modulus, hardness and bending strength) were determined for sintered bodies. To estimate the stress path in the core shell bodies loaded in bending, the relationship considering different elastic moduli of the core and the shell was used. For bodies of ZTA-A system was increased the strength in comparison with monolithic bodies of the individual components. Thus, bodies with high surface hardness of shell from Al2O3 and moreover having high fracture strength in bending were obtained. The effective elastic modulus was decreased for bodies of ZST-Z system up to 25 % in comparison with the elastic modulus of dense monolithic samples. The same effective modulus of elasticity was possible to achieve with core-shell bodies while maintaining significantly higher fracture strength than monolithic porous bodies or pipes.

Presented thesis deals with the settlement archaeology of the Roman Period in Bohemia and then introduces in detail also the findings of the Holubice settlement in the Prague-west district in this period. The work is mainly focused on processing and evaluation of archeological research at the sites "Kozákova zahrada" and "Na Ovčárně", which took place under the leadership of Vladimír Sakař between years 1977-1989. There was uncovered a part of the settlement from the younger part of early Roman Period and from the beginning of late Roman Period. Pottery sherds were evaluated with quantitative and qualitative analysis. The thesis also includes the analysis of unearthed objects and the outline of a shift of the land register of Holubice based on mapping of finds which were acquired through field exploration and detector survey. The thesis includes tables with drawings of shards of the pottery made by the author of this thesis (unless otherwise indicated) and also map tables from the archeological research and other inserts.

CSÁKI, Štefan: Thermophysical and electrical properties of illite-based ceramics. [Doctoral thesis]. Constantine the Philosopher University in Nitra. Faculty of Natural Sciences. Charles University. Faculty of Mathematics and Physics. Supervisor: prof. RNDr. Libor Vozár, CSc. (Constantine the Philosopher University in Nitra), doc. Ing. Patrik Dobroň, PhD. (Charles University). Nitra & Prague, 2018. 107 p. Illitic clays are of special importance in the ceramic industry. Therefore, a deep knowledge of the thermophysical processes, as well as the electric properties, is of special importance. The illitic clay originated in Northeastern Hungary was used in this thesis. The reactions, occurring during firing, were studied using thermal analyses (Differential thermal analysis, Thermogravimetry, Thermodilatometry) and special attention was paid to the measurement of the electrical conductivity (both DC and AC). Up to 250 řC, where the removal of the physically bond water (PBW) takes place, the dominant charge carriers were the H+ and OH- ions. After the PBW was removed, Na+ and K+ ions became the dominant charge carriers. During dehydroxylation (450 - 750 řC) H+ and OH- ions were freed from the illite structure, which supported the electrical conduction in the samples. At ~ 970 řC glassy phase appeared...

This thesis presents archaeological finds from the site "U silnice", in municipality Plaňany (district Kolín), where a settlement from roman period has been found during excavations in 2016 and 2017. An assemblage of excavated finds consists mostly of ceramic, animal bones and daub. The aim of the thesis is to describe qualitative and quantitative attributes of these finds. Results will be used to validate and compare properties of individual archaeological contexts. Main goal is to place the site into regional network of settlements and cemeteries from roman period. Potential of the site rises from the fact that it is the only settlement from roman period excavated by modern methods in the region and therefore it represents a valuable source of new information. Keywords (a. j.): Roman period; Settlement; Archaeological Sites; Pottery; Typology

Three pottery assemblages from the Yambol District were processed in this thesis to enrich our knowledge about the Roman and Late Antique pottery material in Ancient Thrace. The first, and most abundant assemblage, is from the Roman vicus called Yurta, which is located near the village of Stroyno and dated from the 1st /2nd c. AD till the Late Antiquity. This assemblage is substituted by different pottery classes which give us bases for identifying the variability of the pottery material and the different wares and fabrics in the area. In addition, it represents the main material for statistics and for a quantitative comparison of individual classes. The second assemblage includes 19 complete vessels from two burial mounds in Palauzovo, dated to the 2nd -3rd c. AD, and gives a comparative sample for the settlement contexts as well as a basis for studying the ways in which pottery was modified for special burial purposes. The last set of 57 vessels comes from a closed context dated to the end of the 6th c. AD, which was found in a collapsed house at the Dodoparon hillfort, rising above the village of Golyam Manastir. It represents a unique set of finds from the Late Antiquity, which is well dated and preserved. The three pottery assemblages are all different, each with a distinct character, which...
