Oweing to the suitable coefficient of thermal expansion and refractive index of lithium disilicate crystals, lithium disilicate glass-ceramics could obtain high mechanical strength and translucent effect simultaneously, which show a brilliant future in dental aesthetic restorations. The purpose of the study was to investigate the effects of glass composition, content of P2O5 and heat treatment procedures on microstructure and properties of final glass-ceramic products.

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。

The high mechanical properties of dental lithium disilicate glass-ceramics were attributed to the relatively high crystalline content, residual stress and the interlocking microstructure.

Formylation and diformylation of dithieno [2,3-b:3',2'-d] thiophene were prepared by two methods. Firstly, aromatic carbanions were prepared by 1 Br/Li exchange of bromo dithieno[2,3-b:3',2'-d]thiophene with n-BuLi in THF at low temperature; 2 deprotonation of dithieno[2,3-b:3',2'-d]thiophene with LDA.
