Scintillation ceramic for double-layer detector and preparation method of scintillation ceramic
The invention discloses scintillation ceramic for a double-layer detector and a preparation method of the scintillation ceramic. The method comprises the following steps: raw materials A and B are weighed respectively in a stoichiometric ratio, wherein A is lower scintillation ceramic and B is upper scintillation ceramic; a precursor of A and a precursor of B are synthesized respectively; the precursor of A and a precursor of B are prepared to form slurry; the two kinds of prepared slurry are subjected to tape casting respectively to prepare a biscuit of A and a biscuit of B; the biscuit of A and the biscuit of B are cut respectively and stacked to form a double-layer scintillation ceramic biscuit with A on the lower layer and B on the upper layer; the double-layer scintillation ceramic biscuit is subjected to hot pressed sintering to prepare a double-layer scintillation ceramic sintered body; the double-layer scintillation ceramic sintered body is polished to prepare the required scintillation ceramic for the double-layer detector. The double-layer scintillation ceramic can be formed once, the process is simple and convenient to operate, the production cycle is shortened, and the production cost is saved.
