The traditional solid phase reaction of preparation has many disadvantages: it is very difficult to get the pure calcium-titanium mine phase even at the annealing temperature of 1000DEG C; the size of the material is very large and ununiform; the powder needs very high agglutinating temperature (1350DEG C) to get pyknotic ceramics.
固相反应法制备铌钪酸铅，在1000℃的较高的煅烧温度下也难于得到纯钙钛矿相的粉体，且颗粒尺寸大，尺寸分布不均匀，且这种粉体而要求高的烧结温度(1350℃)以获得致密的陶瓷。
