Potassium titanate whisker reinforced silicon-based ceramic core 3D printing preparation method
The invention relates to a potassium titanate whisker reinforced silicon-based ceramic core 3D printing preparation method, which comprises: carrying out dry mixing on quartz glass powder, zirconium silicate powder and potassium titanate whiskers to prepare a ceramic core material, further adding light-cured resin, carrying out ball milling blending to obtain ceramic core slurry, carrying out 3D printing layer-by-layer curing to obtain a ceramic core biscuit, putting the ceramic core biscuit into light magnesium oxide powder of a ceramic sagger, sintering in a core sintering furnace to obtain a ceramic core, and finally reinforcing with ethyl silicate hydrolysate to obtain the potassium titanate whisker reinforced silicon-based ceramic core. The high-temperature strength of the silicon-based ceramic core is remarkably improved, and meanwhile, the silicon-based ceramic core can keep good alkali liquor dissolution performance.
一种钛酸钾晶须增强的硅基陶瓷型芯3D打印制备方法，通过将石英玻璃粉、硅酸锆粉和钛酸钾晶须干混制成陶瓷芯料后进一步加入光固化树脂并球磨共混得到陶瓷型芯料浆，经过3D打印逐层固化得到陶瓷型芯素坯，再将陶瓷型芯素坯置于陶瓷匣钵的轻质氧化镁粉中，在型芯烧结炉中烧结得到陶瓷型芯，最后经硅酸乙酯水解液强化后得到钛酸钾晶须增强的硅基陶瓷型芯。本发明使硅基陶瓷型芯在显著提高高温强度的同时，能够保持良好的碱液溶出性能。
