Prestressed ceramic and preparation method thereof
The invention belongs to the technical field of prestressed ceramics, and particularly relates to a prestressed ceramic and a preparation method thereof.The prestressed ceramic comprises a green body and a prestressed layer located on the surface of the green body, and the thermal expansion coefficient of the prestressed layer is smaller than that of the green body; the prestressed layer is prepared from the following raw materials: metal superfine powder, metal oxide superfine powder, an organic solvent, an organic additive, superfine palladium powder, calcite, kaolin, quartz, spodumene, zinc oxide, barium carbonate and frit; the frit is prepared from the following components in parts by weight: 5-10 parts of the frit, and the frit is reasonable in structure, uniform in distribution, high in structural strength, long in service life, simple in production process, low in production cost and high in economic benefit in the use process.
本发明属于预应力陶瓷技术领域，具体为一种预应力陶瓷及其制备方法，包括坯体和位于坯体表面的预应力层，所述预应力层热膨胀系数小于坯体的热膨胀系数，所述预应力层的原料包括：金属超细粉、金属氧化物超细粉、有机溶剂、有机添加剂、超细钯粉、方解石、高岭土、石英、锂辉石、氧化锌、碳酸钡和熔块；熔块按照重量份计由以下成分例制成：5‑10份，其结构合理，在使用的过程中，分布均匀，结构强度高，使用寿命长，同时生产工艺简单，生产成本低，经济效益高。
