It was concluded that P2O5 was an effective nucleating agent for this glass system. The nucleation density of this glass system was too low to form tiny crystal after heat-treatment, when it contained no P2O5, and the major crystal phase was lithium silicate. Adding P2O5 resulted in major tiny crystal phase of lithium disilicate after heat-treatment.

结果发现P2O5是该玻璃体系的有效成核剂，未添加P2O5的玻璃体系成核密度低，热处理后不能形成微晶体，且主晶相为硅酸锂；添加P2O5使玻璃在热处理后形成以二硅酸锂为主晶相的微晶玻璃。

目前，玻化砖中乳浊剂主要采用的是锆英石，其增白机理是在玻化砖中形成硅酸锆晶体，利用硅酸锆晶体与玻璃相之间的折射率差使可见光发生散射，从而产生增白效果。

Metal/ oxide composite aerogels can be used as catalysts because of their high specific surface area. In this paper, Co-rich Co/SiO2 composite aerogels in which mass fraction of Co can reach 66%were firstly prepared by sol - gel process of Co-containing tetraethyl orthosilicate. The influence of H2O, catalyst, solvent and composition of Co-containing tetraethyl orthosilicate on the sol-gel process are discussed.
