Honeycomb ceramic and preparation method thereof
The invention relates to a ceramic processing technology, in particular to a honeycomb ceramic and a preparation method thereof.According to the honeycomb ceramic, the proportion of an adhesive, a plasticizer, water, a lubricant, a pore forming agent and zirconium dioxide powder is optimized according to a specific proportion, especially during forming, the water content needs to be controlled to be 25%, and the water content needs to be controlled to be 25%; the highest sintering temperature needs to reach 1700 DEG C; according to the present invention, the specific types are selected, and the specific preparation method is matched, such that the prepared honeycomb ceramic has characteristics of smooth surface, no crack through visual inspection, bending strength of more than 11 MPa, thermal expansion coefficient of less than or equal to 2 * 10 <-6 > DEG C <-1 >, and convenient promotion and use.
本发明涉及一种陶瓷加工技术，尤其涉及一种蜂窝陶瓷及其制备方法，本发明涉及的蜂窝陶瓷在原料上，通过特定配比的黏结剂，增塑剂，水，润滑剂，造孔剂和二氧化锆粉料的比例优化，特别是在成型时，含水量需要控制在25％，烧结的最高温度需要达到1700℃；以及具体种类的选择，配合特定的制备方法，使制得的蜂窝陶瓷具有表面光滑，经过肉眼观察无裂纹存在、抗弯强度在11MPa以上、热膨胀系数为≤2×10‑6℃‑1，方便推广使用。
