Paper Title:
Preparation and Properties of Low-Cost α-Sialon Ceramic Synthesized from Boron-Rich Slag-Based Mixture
  Abstract

With boron-rich slag, silica fume, bauxite chalmette and carbon black as starting materials, -sialon powder was prepared by carbothermal reduction nitridation(CRN). The mechanical properties of hot-pressed sintered slag α-sialon ceramic, which was started from slag -sialon powder, were measured. The hardness, toughness and bend strength of hot-pressed slag α-sialon ceramic reached 17GPa, 3.74MPam1/2 and 333.5MPa, respectively. These properties were close to that of chemical α-sialon ceramics prepared by expensive chemical agents as starting materials.
