A new approach to the homogenization of the reaction mixture is presented consisting in the creation of glass-ceramic precursors in oxide systems containing enough components for the joint synthesis of carbides and borides mixed at the molecular level. By the joint carbothermal reduction of glass-ceramic precursors in vacuum at 1600 °C fine mixtures in B₄C–SiC–MB₂ systems (M—Ti, Cr, Zr) without or with an insignificant content of impurities were obtained. Due to the good solubility of titania in the silicate-borate melt the microstructure of the ternary B₄ C–SiC–TiB₂ sample is represented by boron carbide crystals up to 1 μm in size surrounded by nanoparticles of 30 – 40 nm.

B 2 O 3 -SiO 2-M x O y系统（M-Ti，Zr，Cr）中的玻璃陶瓷前驱体，用于生产高熔点碳化物和硼化物的精细分散混合物

提出了一种使反应混合物均质化的新方法，该方法包括在氧化物体系中创建玻璃陶瓷前体，该体系中含有足够的组分，用于在分子水平上联合合成碳化物和硼化物。在1600°C的真空中，通过玻璃碳陶瓷前驱体的联合碳热还原，可以得到B ₄ C–SiC–MB ₂系统（M -Ti，Cr，Zr）中无杂质或杂质含量不高的精细混合物。由于二氧化钛在硅酸盐-硼酸盐熔体中的良好溶解性，三元B ₄ C–SiC–TiB ₂样品的微观结构由尺寸最大为1μm的碳化硼晶体代表，并被30–40 nm的纳米颗粒包围。
