High-thermal-shock-resistance ceramic vessel and preparation method thereof
The invention discloses a high-thermal-shock-resistance ceramic vessel and a preparation method thereof. The high-thermal-shock-resistance ceramic vessel comprises a blank and glaze; the blank is prepared from the following raw materials in parts by weight: 40-50 parts of spodumene, 35-45 parts of kaolin, 8-12 parts of quartz and 1-3 parts of bentonite; and the glaze is prepared from the following raw materials in parts by weight: 35-45 parts of spodumene, 15-25 parts of feldspar, 10-20 parts of quartz, 20-30 parts of frit, 5-8 parts of kaolin and 3-5 parts of zinc oxide. The spodumene, the kaolin and the quartz are compounded, the spodumene is converted into a beta-type structure after being calcined in a green body, the lattice structure of the spodumene can absorb SiO2 dissociated from kaolin phase change and SiO2 in the quartz to form a beta-spodumene solid solution, conversion of residual SiO2 to cristobalite with a high thermal expansion coefficient is inhibited, the expansion coefficient of the ceramic vessel is greatly reduced, and when the ceramic vessel is heated to 800 DEG C, the ceramic vessel does not crack after being put into normal-temperature cold water.
本发明公开了一种高抗热震性陶瓷器皿及其制备方法，所述高抗热震性陶瓷器皿包含胚料和釉料；以重量份计，所述胚料由以下原料制成：锂辉石40～50份、高岭土35～45份、石英8～12份、膨润土1～3份；以重量份计，所述釉料由以下原料制成：锂辉石35～45份、长石15～25份、石英10～20份、熔块20～30份、高岭土5～8份、氧化锌3～5份。本发明以锂辉石、高岭土和石英复配，锂辉石在坯体中经锻烧后转变为β型结构，其晶格结构可吸纳高岭土相变游离出来的SiO2和石英中的SiO2，形成β‑锂辉石固溶体，抑制了残余SiO2向热膨胀系数高的方石英转化，大大降低了陶瓷器皿的膨胀系数，使陶瓷器皿耐高温急变性能大大提升，加热至800℃，投入常温冷水中不开裂。
