摘要：

The influence of some nucleating agents on the sintering, crystallization and mechanical properties of SiO2-CaO-MgO (Na2O) glasses was investigated. It was found that the glass-ceramic containing Fe2O3 and Cr2O3 had desirable sintering behavior and reached to an acceptable density. However, the sinterability of specimens was degraded by addition of CaF2 + MoO3 and/or V2O5 + MoO3 through reduction of crystallization temperatures of glasses. In these cases increasing of firing temperature led to reduction of the transition metal oxides and bloating of specimens. (c) 2006 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
