Abstract

Refractory and heat-resistant materials with a coarse-grained and large-porous structure were obtained using silica glass suspensions with mullite, spinel, alumina, and quartz fillers. The influence of sintering temperature on the phase composition, structure, porosity, and density of the materials were studied. Although the strength of the ceramics was found to increase in the temperature range 1300 – 1400°C, it decreases at 1500 – 1600°C due to the crystallization of the silica glass. Composites in the silica glass-alumina system were found to have the most stable strength characteristics.

耐火填料对基于高浓度硅玻璃悬浮液的陶瓷性能的影响

利用含有莫来石、尖晶石、氧化铝和石英填料的硅玻璃悬浮液，获得了具有粗颗粒和大孔隙结构的耐火耐热材料。研究了烧结温度对材料的相组成、结构、孔隙率和密度的影响。虽然陶瓷的强度在 1300 - 1400°C 的温度范围内有所增加，但在 1500 - 1600°C 的温度范围内，由于硅玻璃的结晶作用，强度有所下降。研究发现，硅玻璃-氧化铝体系的复合材料具有最稳定的强度特性。
