High-lithium thermal shock resistant functional ceramic product and preparation method thereof
The invention provides a high-lithium thermal shock resistant functional ceramic product and a preparation method thereof, the ceramic product comprises a blank and a glaze, the blank comprises the following raw materials by weight: 50-58% of eucryptite, 30-35% of kaolin, 8-10% of quartz, 2-3% of bentonite, 1-2% of boric acid, and 0.5-1% of magnesium oxide. The preparation method of the ceramic product comprises the steps of green body preparation, biscuit firing, glazing, firing and the like. The ceramic product which takes eucryptite with higher lithium content as an important raw material through a proper blank material ratio is formed, so that the lithium content is up to 5-6%, the thermal expansion coefficient is very low, the heat resistance is high, the ceramic product can be put into normal-temperature cold water (20 DEG C) at the temperature of 1000-1100 DEG C without bursting, and the heat stability is good.
本发明提供了一种高锂抗热震功能陶瓷制品及其制备方法，陶瓷制品包括坯料与釉料，以重量百分数计，所述坯料由如下原料组成：50～58％的锂霞石、30～35％的高岭土、8～10％的石英、2～3％的膨润土、1～2％的硼酸、0.5～1％的氧化镁。陶瓷制品的制备方法包括坯体制备，素烧，施釉，烧成等步骤。通过合适的坯料配比，以高含锂量更高的锂霞石为重要原料的陶瓷制品，形成锂含量高达5～6％，这样热膨胀系数很低，抗热霞性能强，能在1000～1100摄氏度温度下投入常温冷水(20摄氏度)不炸裂，热稳定性好。
