Comparative studies of the structural features of Gamma porcelain, Sikor glass ceramic, and Cast Glass Ceramic (CGC) by x-ray structural analysis and IR spectroscopy have revealed that improvement of the physical characteristics of stomatological silicate material in transition to glass ceramic is explained by similarity of their composition with lithium disilicate. CGC structure due to convergence of the composition of the major areas of chemical heterogeneities is the most compact as compared to Sikor structure and more so us. Gamma. As evidenced by IR spectroscopy, super microhardness of CGC, observed in practice, appears to be related to their higher solidity in contrast to that of Gamma porcelain, structurally similar to amorphous silica, and that of Sikor characterized by a poorly crystallized tridymite structure. Higher physical characteristics of CGC distinguish it among the known silicate materials used in dentistry and recommend it for wide practice.
通过X射线结构分析和红外光谱对伽马瓷、西科尔玻璃陶瓷和铸玻璃陶瓷（CGC）的结构特征进行的比较研究表明，向玻璃陶瓷转变过程中口腔硅酸盐材料物理特性的改善是由于其成分与二硅酸锂相似。与西科尔结构相比，由于化学不均匀性主要区域成分的趋同，CGC结构最为致密，比伽马结构更是如此。红外光谱证明，在实践中观察到的CGC的超高显微硬度似乎与其更高的坚固性有关，这与结构类似于无定形二氧化硅的伽马瓷以及具有结晶不良的鳞石英结构的西科尔不同。CGC较高的物理特性使其在牙科使用的已知硅酸盐材料中脱颖而出，并推荐广泛应用。
