CaF_2-CaO矿化剂对硅微粉结合的SiC窑具的晶相性能影响的研究

INFLUENCE OF CaO-CaF_2 FUSED MINERALIZER ON THE CRYSTALLINE PHASES,PROPERTIES OF SIC KILN FURNITURE BONDED WITH SUPERFINE SILICON DUST

本研究主要探讨矿化剂对硅微粉结合的SiC窑具的析晶结构、性能的影响。分别添加不同量的混合矿化剂,用XRD法分析硅微粉的析晶结构,并进行半定量计算,选择最佳的矿化剂添加量,分别测定不同矿化剂添加量时窑具的各项宏观性能,进行综合分析,确定CaF-CaO矿化剂的最佳添加量为1.5%。

s:The influence of mineralizer on the crystalline phases, properties of SiC kiln Furniture bonded with superfine silicon dust were studied in this paper. Different amount of fused mineralizer were added and XRD techniques were used to characterize the crystalline phases. On this basis to determine the best amount for mineralizer added. The properties with different amount of mineralizer were tested and were mateched with crystalline phases analysis, the best amount for CaO-CaF fused mineralizer added was determined to be 2 1.5%.
