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 NaZnPO₄ structure,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 NaZnPO₄ structure,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.
