Dobijanje ZrO2 i ZrO2/SiC prahova karbotermalnom redukcijom ZrSiO4

, 2013
Pored značajnog broja istraživanja koja se odnose na procese koji se dešavaju u toku karbotermalne redukcije (KTR) cirkonijumsilikata (ZrSiO4), još uvek postoji potreba za detaljnim izučavanjem ovog procesa u cilju upotpunjavanja saznanja o uticaju molskog odnosa ugljenika i ZrSiO4 (C/ZrSiO4) na moguće proizvode reakcije.
