采用碳热还原氮化法（CRN）合成了Ca-α SiAlON（Y型沸石）粉体。首先在1100°C以下将Ca-Y沸石转化为非晶相，然后在1450°C下通过莫来石、Si_2N_2O和（Ca，Si，Al）_xO_y液相转化为Ca-α SiAlON。在将沸石转化为Ca-α SiAlON的过程中，发现Ca-α SiAlON颗粒的尺寸与原料的尺寸相似，表明可以使用沸石作为原料来控制Ca-α SiAlON的粒度。
Ca-α SiAlON powders were synthesized by carbothermal reduction nitridation (CRN) of zeolite (Ca-zeolite Y). First, the Ca-zeolite Y was converted into an amorphous phase below 1100°C, and then into Ca-α SiAlON via mullite, Si2N2O and (Ca, Si, Al)xOy liquid at 1450°C. In converting zeolite into Ca-α SiAlON, it was found that Ca-α SiAlON particles were of a similar size to that of the raw material, indicating that it is possible to control the particle size of Ca-α SiAlON using zeolite as a raw material.
