本文以ＺｎＯ，ＣａＯ和Ｈ３ＰＯ４为原料，利用水热法合成出一种新型三元化合物－ＺｎＯ·ｘＣａＯ．ｙＰ２Ｏ５。其中，ｘ＝０．２～０．６，ｙ＝０．３～０．８（ｍｏ１）。ＸＲＤ物相分析证明产品主要为无定形态。ＳＥＭ形貌分析产品外观为针状纺锤形，长轴约为１μｍ，短轴约为０．２μｍ。ＩＲ光谱分析产品中的磷酸根离子局部对称性为正四面体结构。性能测试表明该产品在油漆、涂料行业中可用作防锈颜料，以代替传统的锌黄等有毒颜料，其特点是无毒、成本低、防锈性能超过国标１倍。 In this paper, ZnO, CaO and H3PO4 as raw materials, the use of hydrothermal synthesis of a new ternary compound -ZnO · xCaO. yP2O5. Here, x = 0.2 to 0.6 and y = 0.3 to 0.8 (mo1). XRD phase analysis proved that the product is mainly amorphous state. SEM appearance of the product appearance needle-shaped spindle shape, long axis is about 1μm, short axis is about 0.2μm. The local symmetry of phosphate ions in IR spectral analysis products is a regular tetrahedron structure. Performance tests show that the product can be used as anti-rust paint in the paint and coating industry to replace the traditional zinc yellow and other toxic pigments, which is characterized by non-toxic, low cost and anti-rust performance more than double that of the national standard.
