Intermetalinio junginio susidarymas sistemoje Ni-W / Intermetallic phases formation in the system Ni-W

Michailovskaja, Ilona 24 September 2008 (has links)
Redukuojant vandeniliu Ni ir W oksidus 1000-1100˚C temperatūrų intervale, nepriklausomai nuo mišinio sudėties, susidaro tik intermetalinis junginys Ni4W. Rentgeno struktūrinės analizės pagalba buvo nustatyta kietafazių reakcijų produktų sudėtis. Nikelio ir volframo oksidų mišiniuose vykstant redukcijai susidarantis nikelis yra volframo oksidų redukcijos katalizatorius. Nikeliui sudarius intermetalinį junginį Ni4W, volframo oksidai redukuojasi sunkiau. Mišiniai, kuriuose Ni:W=4:1, redukuojasi žemesnėje temperatūroje ir esant mažesnei vandenilio dujų koncentracijai. / During the reduction of nickel and tungsten in a temperature range from1000- 1100˚C independent of composition mixtures form only Ni4W intermetallic compuond. Their formation was analyzed be of the X-ray diffraction techniques composition the products of the solid-state reactions was determined. Nickel wich is formed during the rediction is catalyst of tungsten oxide. When nickel is formed intermetallic compound Ni4W, tungsten oxide reducible heavily. Reduction of mixture (Ni:W = 4:1) lesses of the temperature and hydrogen concentration.
