采用共沉淀法制备钙钦矿氧化物Laz _ X SrX Cu0、及LaSrCu1 _ }. W}.04，通过X-射线衍射( XRD )、比表面测定仪(BET)等技术测试钙钦矿样品的晶体结构及比表面积.XRD测试结果表明，对于Laz _ x Srx CuO4类钙钦矿型氧化物，随着Sr掺杂量的增加，钙钦矿结构的物质杂峰会有所增多;此外，对于LaSrCu, _},Wy04而言，W掺杂量对钙钦矿氧化物的晶型结构的影响较小.比表面实验表明，无论是A位元素部分调整还是B位元素部分取代，Lag _ ASrx Cu04及LaSrCu, _YWj,O、的比表面积都有明显的增加，但是当比例达到某一值后反而会有所下降.
Calcium-rich ore oxides Laz_xSrxCu0 and LaSrCu1_W.O4 were prepared by coprecipitation method, and the results of X-ray diffraction (XRD) and specific surface area analyzer (BET) Crystal structure and specific surface area.XRD results show that for the LaZ_xSrxCuO4 type calcium-based oxide, with the increase of Sr doping amount, the impurity content of calcium-doped ore structure will increase; In addition, LaSrCu , _} And Wy04, the effect of W doping content on the crystal structure of the calcium-based oxide is small.The specific surface experiments show that either the element A or the element B is replaced by Lag_Asrx Cu04 And LaSrCu, _YWj, O, have a significant increase in specific surface area, but when the ratio reaches a certain value but will decline.
