对用燃烧还原合成法制备氮化钛粉末的过程进行了试验研究 ,建立了一种无需机械粉磨处理的直接合成工艺。制备的氮化钛粉末粒径分布为 0 .2～ 1.0 μm ,平均粒径为 0 .5～ 0 .6 μm。研究结果表明 ,副产物氧化镁的机械分割作用是使氮化钛颗粒免于烧结成块的根本原因 ,恰当地控制合成温度可较好地兼顾产物的氮化率与颗粒形态
The process of preparing titanium nitride powder by combustion reduction synthesis was studied experimentally, and a direct synthesis process without mechanical grinding was established. The prepared titanium nitride powder has a particle size distribution of 0.2-2.0 μm and an average particle diameter of 0.5-6.6 μm. The results show that the mechanical separation of by-product magnesia is the basic reason for preventing the titanium nitride particles from agglomeration. Proper control of the synthesis temperature can better balance the nitration rate and the particle morphology of the product
