| Abstract: | Adding fused MnO2-CaF2 Mineralizer into fine silicon powder can change its cryst al structure and improve the amount of tridymite,thus can improve the kiln furni ture's high temperature properties and prolong its lifetime.The crystal structur e and its amount were investigated with XRD technique.The kiln furniture's prope rties,such as bending strength,bending strength stability,porosity and water abs orption,were tested.By the synthesis results,we can conclude that the best amoun t for MnO2-CaF2 added was determined to be 2.0%. |
