The effect of K2O on the crystallization of niobium germanate glasses
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2011)
Ispitan je uticaj sadržaja K2O na kristalizaciju niobijum germanatnih stakala sa 22,7-24,27 mas % GeO2 i 54,59-57,48 mas % Nb2O5. Ova stakla kristališu primarnom kristalizacijom i stvaraju se kristalne faze K6Nb6Ge4O26, ...
Sintering of Cordierite in the Presence of MoO3 and Crystallization Analysis
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Cordierite (MAS) is difficult to sinter because of the very narrow sintering temperature range (1300-1400 degrees C). Because a low temperature process is desirable, it is necessary to find functional ads which can allow ...
