Novel composite ceramic kiln furniture and preparation method and application thereof

The invention provides a preparation method and application of novel composite ceramic kiln furniture, and belongs to the technical field of refractory materials. In the composite material preparation process before ceramic kiln furniture is prepared, the required composite material is synthesized through in-situ reaction at high temperature, the alkali corrosion resistance of magnesium salt can be fully utilized, the product stability is enhanced, and the thermal shock resistance is greatly improved; the required product prepared from the composite material has the advantages of high use temperature, long-term use temperature of less than or equal to 1650 DEG C, good thermal shock resistance, acid and alkali corrosion resistance, especially alkali corrosion resistance and lead corrosion resistance. 本发明提出一种新型复合陶瓷窑具的制备方法及应用，属于耐火材料技术领域；在陶瓷窑具制备前的复合材料制备过程中，通过高温下原位反应合成所需要的复合材料，该方法能够充分利用镁盐的耐碱腐蚀能力，并增强产品稳定性，大大提高了抗热震性；用这种复合材料制备出的所需要的产品具备使用温度高，可长期使用温度≤1650℃、抗热震性好、耐酸碱腐蚀，尤其是耐碱腐蚀和耐铅腐蚀的优点。
