Forming method of rare earth praseodymium holmium stable silicon nitride ceramic
The invention discloses a forming method of rare earth praseodymium holmium stable silicon nitride ceramic, which comprises the steps of S1, preparing materials, specifically, weighing silicon carbidepowder, a sintering aid, a binding agent, an acrylamide organic monomer, a catalyst and phosphate glass for later use; S2, mixing, specifically, adding silicon carbide powder, a sintering aid, a binding agent, an acrylamide organic monomer, a catalyst and phosphate glass into a mixer for dry mixing, and adding water for mixing to obtain slurry; S3, filtering and pressurizing, specifically, filtering the slurry, and pumping the filtered slurry into a static pressure machine for pressure molding; S4, green body preparation, specifically, carrying out photocuring molding on a green body subjected to static pressure molding; and S5, conducting degreasing and cleaning, specifically, degreasing the solidified and formed green body, and conducting degreasing after the slurry is mixed, photocuredand formed, so that the air degree in the green body is reduced, the quality after forming is improved. Meanwhile, when the green body is prepared, the pressure value in the green body is increased by pressurizing the green body, the strength is higher, and the forming speed is higher.
本发明公开了一种稀土镨钬稳定氮化硅陶瓷的成型方法，包括如下步骤：S1、备料：将碳化硅粉、烧结助剂、结合剂、丙烯酰胺有机单体、催化剂和磷酸盐玻璃进行称重备用，S2、混合：将碳化硅粉、烧结助剂、结合剂、丙烯酰胺有机单体、催化剂和磷酸盐玻璃加投入混料机进行干拌混合，在加入水混合得到浆料，S3、过滤加压：将浆料进行过滤，过滤完成后泵入静压机加压成型，S4、胚体制备：将静压成型后的胚体进行光固化成型，S5、脱脂清洗：将固化成型后的胚体进行脱脂，通过将浆料混合光固化成型后进行脱脂，降低胚体中的空气度，增加成型后的质量，同时在胚体制备时通过对胚体进行加压，提高胚体中的压力值，使得强度更高，成型速度更快。
