Preparation of Ca-substituted α-Sialon Eco-materials by Utilizing Tungsten Molybdenum Bismuth Polymetallic Tailings

摘要：

This presented a route to utilize the Tungsten Molybdenum Bismuth Polymetallic Tailings in Shizhuyuan of Hunan province to fabricate Ca-substitued α-Sialon eco-materials. The reaction mechanism in carbothermal reduction nitridation process was widely studied by separately considering the effect of sintering temperature and soaking time. Based on the optimized conditions, a composite containing 78％ Ca-based α-Sialon has been fabricated at 1600℃ for 8h.
