Ceramic mold and preparation method thereof
The invention discloses a ceramic mold and a preparation method thereof. The preparation method comprises the steps that NixM1-xFe2O4 powder, ZrB2 powder, Na0.44MnO2 powder, germanium oxide powder andabsolute ethyl alcohol are mixed, ball-milled and dried, and mixed powder is obtained; the mold is pretreated; the mixed powder is put into a pretreated mold, and hot pressed sintering is carried out; wherein x is greater than or equal to 0.4 and less than or equal to 0.8, and M is one of Co, Ba or Zn. The preparation method of the NixM1-xFe2O4 comprises the following steps of adding oleic acid and a mixture of oleic acid compounds containing ferric oleate, nickel oleate and M into a heptane solution, uniformly stirring, adding into a reaction kettle, treating the reaction kettle in a dryingoven, cooling, centrifugally separating and cleaning. The ceramic mold is high in strength and hardness, excellent in abrasion resistance, chemical corrosion resistance and thermal shock resistance and good in toughness.
本发明公开了一种陶瓷模具及其制备方法，其步骤包括：将NixM1‑xFe2O4粉、ZrB2粉、Na0.44MnO2粉、氧化锗粉与无水乙醇混合，球磨，干燥，得到混合粉料；对模具进行预处理；将混合粉料置于预处理后的模具内，进行热压烧结；其中，0.4≤x≤0.8，M为Co、Ba或Zn中的一种；上述NixM1‑xFe2O4的制备方法为：将油酸和含油酸铁、油酸镍与M的油酸化合物的混合物，加入庚烷溶液中，搅拌均匀后加入反应釜中，将反应釜置于烘箱中处理，冷却，离心分离，清洗。该陶瓷模具强度与硬度高，具有优异的耐磨性、耐化学腐蚀性、抗热震性，同时具有较好的韧性。
