Ceramic heating element with high thermal shock resistance and preparation method thereof
The invention relates to the technical field of heating bodies, in particular to a high-thermal-shock-resistance ceramic heating body and a preparation method thereof.The high-thermal-shock-resistance ceramic heating body is formed by combining a casting substrate, a ceramic blank tube and a thick film printed heating layer; comprising the following ceramic powder in parts by weight: 65-90 parts of aluminum oxide, 5-20 parts of zirconium oxide, 0.1-5 parts of ceramic fibers or whiskers, 0.1-5 parts of a sintering aid and 0.1-5 parts of a low-thermal-expansion base material; and preparing the slurry adaptive to a tape casting substrate, an isostatic pressing forming blank tube and a thick film printing heating layer. According to the ceramic heating element with the high thermal shock property, the substrate formed through tape casting, the blank tube formed through spray granulation and isostatic pressing and subjected to biscuit firing and glue discharging and the thick film slurry added with formula ceramic powder are printed on the substrate, and the heating element prepared by combining the blank tube and the thick film printing substrate has the advantages of high thermal shock property, low expansion coefficient, high strength and good insulating property.
本发明涉及发热体技术领域，具体涉及一种高热震性陶瓷发热体及其制备方法，由流延基片、陶瓷胚管和厚膜印刷的发热层组合而成，包括如下重量份的陶瓷粉体：氧化铝65‑90份、氧化锆5‑20份、陶瓷质纤维或晶须0.1‑5份、烧结助剂0.1‑5份、低热膨胀基料0.1‑5份；并将其配制成适配流延成型基片，等静压成型胚管以及厚膜印刷发热层的浆料。本发明中的高热震性陶瓷发热体，将流延成型的基片与喷雾造粒等静压成型经素烧排胶后的胚管，以及加配方瓷粉的厚膜浆料印刷于基片，并将胚管与厚膜印刷基片组合制得的发热体具有高热震性、低膨胀系数、高强度、绝缘性能好的优点。
