硬质瓷

又称硬瓷.指具有较高的机械强度，良好的介电指标，高度的 化学稳定性和热稳定性的瓷器.它釉面硬度高，坯料中含 碱性氧化物少而含ＡＩ２Ｏ３量高（坯料配方中的粘土矿物含量在４０％以上）。烧成温度高，一般在１３０℃以上.主要用于高级日用瓷、化学瓷和电瓷等. Also known as a hard porcelain. Refers to have a high mechanical strength, good dielectric targets, a high degree of chemical stability and thermal stability of porcelain. It is glazed, high hardness, billets containing alkaline oxides which contain a small amount of high-AI2O3 (blank formulations of clay mineral content of 40% and above). Firing temperatures are high, generally above 130 ℃. Is mainly used for high-level porcelain, chemical porcelain, and porcelain and so on.
