研究了氟碳铈矿晶体配 Si O2 球团 ,在 10 0 0℃、12 0 0℃温度条件下煅烧时稀土硅酸盐的生成情况。结果表明 ,稀土原料和 Si O2 直接造球 ,在 10 0 0℃温度条件下 ,就有稀土硅酸盐的生成。
The formation of rare earth silicates during the calcination of bastnaesite crystals with Si O2 pellets at temperatures of 100 ℃ and 1200 ℃ was studied. The results show that rare earth materials and Si O2 directly pelletizing, at a temperature of 100 ℃, there is rare earth silicate formation.
