Abstract

A technique was tested for structuring a finely dispersed bulk ferrosilicoaluminum powder by cryogels based on an aqueous poly(vinyl alcohol) solution to prepare products of a desired shape using porous nitride-containing ceramics as a structural material. The physical and mechanical properties of the produced samples were investigated. It was found that the materials obtained after preliminary cryostructuring of the initial powder and subsequent self-propagating high-temperature synthesis in a nitrogen atmosphere are characterized by high strength and porosity.

用于含氮化物陶瓷生产的精细分散硅铁铝的结构化

摘要

测试了一种通过基于聚（乙烯醇）水溶液的冷冻凝胶构建精细分散的块状硅铝铁粉的技术，以使用含氮化物的多孔陶瓷作为结构材料制备所需形状的产品。研究了制备的样品的物理和机械性能。发现初始粉末经过初步低温结构化和随后在氮气氛中自蔓延高温合成后获得的材料具有高强度和孔隙率的特点。
