碳化硅质高温陶瓷膜的低温烧成

本文以碳化硅骨料、章村土系结合剂和核桃壳粉为原料，通过等静压成型工艺和 低温烧结制备了碳化硅质高温陶瓷膜材料。研究了成型压力对坯体强度以及成型压力和烧成温 度对膜材料强度、孔径、气孔率和透气阻力的影响。结果发现，当成型压力为 70 MPa、烧成温 度为 1250~1270?C 时，制品综合性能较优。

Low Temperature Firing of SiC-Based High Temperature Ceramic Membrane

In this paper, silicon carbide high temperature ceramic membrane materials were prepared by isostatic pressing and low temperature firing using silicon carbide aggregates, chapter binders of Zhangcun clay and walnut shell powders as raw materials. The effects of molding pressure on the strength of the green body and the effects of molding pressure and firing temperature on the strength, pore size, porosity and gas permeability of the sintered membrane materials were investigated. It was found through the performance comparison that, when the molding pressure is 70 MPa and the firing temperature is in the range of 1250°C ~ 1270°C, the product exhibits the best comprehensive performance.
