| Abstract: | Anorthite/mullite composite refractories was prepared using kyanite, suzhou clay, semi-hydrated gypsum and high alumina bauxite as raw materials and Ca(OH)_2 additive as calcium source. The influence of raw materials ratio and reaction temperature on phases and microstructure of the composite refractories was studied by XRD and SEM. The results show that the composite refractories can be prepared at 1400 ℃ for 3 h by high temperature solid state reaction method. The main phases of the composite are Anorthite and mullite. |
