RESEARCH ON PREPARATION OF ALN FOR REFRACTORIES WITH CARBOTHERMAL REDUCTION METHOD
Author(s): 
Pages: 8-11
Year: Issue:  6
Journal: HENAN METALLURGY

Keyword:  AlN碳热还原耐火材料;
Abstract: AlN在很多方面具有优异的性能,它在耐火材料中的应用日益引起人们的关注.但是,由于高纯AlN价格昂贵,限制了它在耐火材料领域的使用.本文采用碳热还原法研究了不同反应温度、反应时间、铝源及原料粒度对AlN制备结果的影响.结果表明,以400目的Al(OH)3在1500℃下,反应5h,即可制备出低成本、适合耐火材料用AlN.
