摘　　要：把天然矿物原料长石、石英和双飞粉、碳酸钡、氧化锌等粉料混匀,然后在熔块窑炉中熔融成玻璃液.经水淬,筛分成具有一定粒级的碎粒,干燥后置于模具中压实、压平,于辊道窑中晶化烧结成微晶玻璃陶瓷板.同样,也可以把上述熔块小颗粒用布料器在素坯上布料,经滚筒把熔块压平、压实,然后进辊道窑晶化,烧结成微晶玻璃陶瓷.制成的微晶玻璃陶瓷板产品的莫氏硬度为6.5,光泽度为98 Gs(光泽单位)以上,抗弯曲强度为31.4 MPa,抗压强度为450 MPa,吸水率为0.1%,具有耐急冷急热、耐酸碱、耐污染的能力.The powders of natural minerals and precessing ingredient including feldspar, quartz, calcium carbonate, barium carbonate, zinc oxide were mixed together, and were melted into glass liquid in smelting furnace. After being treated by water, the dried glass substances of small pellet were shaped in a model, and then were sintered into microcrystal glass-ceramics in roller furnace. Its hardness strength, luster strength, resistance against winding strength, resistance against pressure strength and water absorption partcularly are 6. 5, 98 Gs, 31.4 MPa, 450 MPa and 0. 1%, respectively. It possess good resistance against quick cooling and heating and heat, acid-alkuli surroundings, and pollution.
