A thorough study of phase separation in borosilicate glasses synthesized in the material system soda – colemanite – quartz sand was performed. The ranges of crystallization-resistant glasses and phase separation prone glasses were determined. It is shown that the complex raw material colemanite can be used to obtain glasses that are transparent or opaque in the bulk. The limiting content of raw materials in the material makeup of glass batches are recommended.

在材料系统中合成的硼硅酸盐玻璃中的相分离苏打水–钙锰矿–石英砂

进行了彻底的研究，研究了在苏打–钙锰矿–石英砂材料系统中合成的硼硅酸盐玻璃的相分离。确定了抗结晶玻璃和易于相分离的玻璃的范围。已表明，复合原料硬锰矿可用于获得块状透明或不透明的玻璃。建议在玻璃批次的材料组成中限制原材料的含量。
