High thermal shock resistant cordierite heatproof boccaro ceramic and preparation method thereof
The invention discloses a high thermal shock resistant cordierite heatproof boccaro ceramic. The green body of the ceramic comprises the following raw materials by weight percentage: 40-70% of boccaro soil, 5-30% of talc, 5-15% of kaolin, and 1-15% of spodumene. The main crystal phase of the boccaro ceramic green body is cordierite, and the thermal expansion coefficient alpha is 1.6-2.5*10<-6>/DEG C. In addition, the invention also discloses a preparation method of the high thermal shock resistant cordierite heatproof boccaro ceramic. The heatproof boccaro ceramic is formed by cordierite, which has good thermal shock resistance, can tolerate 600DEG C-20DEG C heat exchange without cracking, can be used for electric heating and also can be heated by open fire, thereby enlarging the application fields of boccaro. At the same time, the preparation process is simple and practicable, greatly reduces the production cost, and is conducive to popularization and application and realization of industrialization, thus having broad market prospects.
