Inorganic mineral composition capable of being porcelainized at low temperature
The invention discloses an inorganic mineral composition capable of being porcelainized at low temperature, which comprises a sintered base material and a complex, the sintered base material comprises spodumene and plastic clay, the sintered base material comprises zinc oxide and free silicon dioxide, the complex comprises 60-79 mol% of silicon dioxide, 9-12 mol% of aluminum oxide, 10-20 mol% of magnesium oxide, 10-20 mol% of magnesium oxide, 10-20 mol% of magnesium oxide and 10-20 mol% of magnesium oxide. 0-20 mol% of zinc oxide, 0-7 mol% of magnesium oxide, 2-5 mol% of calcium oxide and 0-7 mol% of lithium oxide; the inorganic mineral composition prepared by mixing the complex and the sintered base material at least contains 55-74% of silicon dioxide, 18-32% of aluminum oxide and 1.5-4.5% of lithium dioxide, the sintered base material and the complex are mixed, and crystals with low thermal expansion coefficients are formed in the complex, so that the inorganic mineral composition is prepared. A large number of crystals with low thermal expansion coefficients are formed on the surface of the sintered base material and in the sintered base material, so that the smooth, compact and hard ceramic is obtained during cooling, and the ceramic is non-porous and has good thermal shock resistance.
本发明公开了一种可低温成瓷化的无机矿物组合物，包括烧结基材以及络合物，所述烧结基材由锂辉石和塑性黏土组成，所述烧结基材包括氧化锌和游离二氧化硅组成，所述络合物包括60‑79mol％的二氧化硅，9‑12mol％的氧化铝，0‑20mol％的氧化锌、0‑7mol％的氧化镁、2‑5mol％的氧化钙和0‑7mol％的氧化锂；所述络合物与所述烧结基材混合制备的所述无机矿物组合物至少含有55‑74％的二氧化硅，18‑32％的氧化铝以及1.5‑4.5％的二氧化锂，本发明将烧结基材与络合物混合，在络合物中形成热膨胀系数低的晶体，并在所述烧结基材表面以及内部形成含有大量热膨胀系数低的晶体，从而在冷却时获得光滑、致密、坚硬的陶瓷，该陶瓷无孔且具有良好的抗热震性。
