Al2O3-BN composite ceramic and preparation method thereof
The invention discloses an Al2O3-BN composite ceramic, belongs to the technical field of ceramic materials, and particularly discloses the following raw materials in parts by weight: 30-50 parts of BN, 35-70 parts of Al2O3, 1-0.2 part of Y2O3, 0.2-3 part of CaO and 0.2-3 part of MgO. Meanwhile, the invention discloses a preparation method of the composite ceramic. The preparation method specifically comprises the following steps: (1) weighing the raw materials according to the weight parts of the raw materials of the Al2O3BN composite ceramic material, and (2) mixing the raw materials, carrying out ball milling to obtain powder, carrying out cold pressing granulation on the powder to obtain particles, putting the particles into a mold, carrying out hot pressing sintering molding, and demolding to obtain the Al2O3BN composite ceramic material. The product disclosed by the invention can be machined according to drawing requirements, so that the application range of the aluminum oxide multiphase ceramic is expanded, and industrial popularization is facilitated.
本发明公开了一种Al2O3‑BN复相陶瓷，属于陶瓷材料技术领域，具体公开了包括以下重量份数的原料：BN 30‑50份、Al2O350‑70份、Y2O30.1‑0.2份、CaO 0.2‑0.3份和MgO 0.2‑0.3份。同时公开了该复相陶瓷的制备方法，具体包括以下步骤：(1)按照上述一种Al2O3‑BN复相陶瓷材料原料的重量份称取各原料；(2)将原料混合球磨得粉料，然后将粉料进行冷压造粒得颗粒，再将颗粒装入模具进行热压烧结成型，出模得到Al2O3‑BN复相陶瓷材料。本发明中的产品能够根据图纸要求进行机械加工，进而有利于扩大氧化铝复相陶瓷的应用范围，有利于工业化推广。
