摘要/Abstract

摘要： 采用共沉淀法制备了四元体系ZnO-Fe₂O₃-Na₂O-P₂O₅作为太阳热反射材料．用紫外-可见光-近红外分光光度计、XRD对产物进行表征．结果表明：当zn/Fe摩尔比为9.00、在700℃下煅烧时，产物的物相组成随Zn/P摩尔比(1.52、1.02、0.76、0.61)而变化，其中Zn/P摩尔比为0.6l的产物为空间群P2₁/n的单相NaZnPO₄ 结构，其余Zn/P摩尔比下的产物为多相结构；当Zn/P摩尔比为0.61、在700℃下煅烧时，不同Zn/Fe摩尔比(19.00、9.00、5.67、4.00)的产物均为单相NaZnPO₄ 结构，且随zn/Fe摩尔比降低，产物颜色加深，反射比降低；当Zn/P摩尔比为0.61、Zn/Fe摩尔比为9.00时，500～800 ℃煅烧温度范围内的产物均为单相NaZnPO₄ 结构，且随煅烧温度增加，产物颜色加深，反射比降低，其中，600℃ 煅烧产物呈橘红色且近红外波段反射比为80.7% ，700℃ 煅烧产物呈红色且近红外波段反射比为72.2% ．

Abstract:

A kind of solar heat reflection material,Na₂O-ZnO-Fe₂O₃-P₂O₅,was prepared via coprecipitation and was characterized by means of UV-Vis-—NIR spectroscopy and XRD.The results show that(1)when the Zn/Fe no-lar ratio is 9.00,the phase composition of the products calcined at 700℃ varies with the Zn/P molar ratio(1.52,1.02,0.76 and 0.61),in which a Zn/P molar ratio of 0.61 may result in a single-phase NaZnPO4 structure while the other ratios may result in multiphase structures;(2)when the Zn/P molar ratio is 0.61,the phase composition of the products calcined at 700 oC is independent of the Zn/Fe molar ratio(19.00,9.00,5.67 and 4.00),with all the products being of a single-phase NaZnPO₄structure,however,these products become dark and the reflee-tance decreases with the decrease of the Zn/Fe molar ratio;and(3)at a Zn/P molar ratio of 0.61 and a Zn/Fe molar ratio of 9.00,the products calcined at 500～800℃ are all of a single-phase NaZnPO₄structure,and the Droducts become dark and the reflectance decreases with the increase of the calcination temperature,for instance,the DIl0ducts calcined at 600 and 700℃ are respectively orange and red,with their reflectance being 80.7% and 72.2%,respectively.
