Paper Title:
Preparation of Bauxite-Based Homogenized Mullite Grogs with Bauxite and Coal Gangue
  Abstract

The sintering behavior, physical properties and heat processing changes of bauxite-based homogenized grogs prepared by homogenization process and high temperature sintering using bauxite as starting material were investigated. Results show that the bauxite-based mullite can be synthesized by the method, sintering temperature with and without MgO/CeO2 sintering aids are 1600°C and 1700°C separately, the mullite with apparent porosity of<1.0% and 2.5%, bulk density of ≥2.87g•cm-3 and 2.75g•cm-3, Refracteriness-Under-Load(RUL) 1600°C and 1620С; changes in the heat processing is divided into three stages: dehydration stage(400°С~900°С ), primary mullitization stage(1000°С ~1200°С) and secondary mullitization stage(>1200°С).
