The utilization proportions are more than 70%. But the composition of gangues is complex and their melting point is high, so that they must be added additives to reduce their melting point.

论文中采用的福建沙县田口钾长石尾矿和北京平谷金矿尾矿两种尾矿中二氧化硅(SiO_2)含量高，可以用于制备玻璃，为制备泡沫玻璃提供主要原料，尾矿的利用率达到70％以上。

Malachite Green (C.I. Basic Green 4) MG, Guinea Green (C.I. Acid Green 3) GG and Reflex Blue R54 (C.I. Pigment Blue 61) RB were embedded into silica matrices via sols synthesized by hydrolysis of TEOS in water and ethanol.

孔雀绿(正一碱性绿4 )镁，几内亚绿(酸性绿3 ) GG和反射蓝色晴空(颜料蓝61 )经常被嵌入到二氧化硅矩阵经溶胶合成水解的TEOS在水和乙醇。

The iron hydroxide particles prepared above were coated with cobalt by surface adsorption-precipitation reaction. The low pH and Co〓 concentration of suspended system can prevent the nanoparticle from heterocoagulation. The saturation magnetization of MP particles with uniform cobalt hydroxide layer is 10％ higher than that of the α-Fe. And a close SiO〓 layer can improve the coercivity by about 92％.

铁黄粒子表面吸附-反应沉积钴过程中较低的pH值和浓度有利于形成均匀的钴氢氧化物包覆层，可避免形成异相凝聚现象，使比饱和磁化强度提高10％；表面包覆二氧化硅形成致密的薄膜，使矫顽力提高92％。

The results showed that the SiO2-coated yellow iron oxide pigments had good performances in color transformation, disperse stability, capacity of absorptive oil.

结果表明，均匀包覆二氧化硅可有效改善铁黄颜料的综合性能。
