Artificially synthesized tetragonal system petalite and manufacturing method thereof
The invention relates to a manufacturing technology for artificially synthesizing tetragonal system petalite, in particular to a technical scheme for synthesizing specific silicate mineral crystals bytaking rich silicate minerals, chemical raw materials and the like as component raw materials, referring to a natural petalite chemical metering value range and referring to a ceramic production process flow and a technical means. The synthetic product tetragonal system petalite is an isomer of monoclinic system natural petalite, and the product is superior to the natural petalite in the aspectsof lithium-containing grade, thermal negative expansion performance, material purity and the like. Meanwhile, the production and manufacturing cost is lower than the market price of imported petalite,and the method has positive and far-reaching significance in breaking through the bottleneck constraint of natural petalite resources, broadening the supply source of heat-resistant ceramic raw materials and improving the quality of daily heat-resistant ceramic products.
本发明涉及一种人工合成四方晶系透锂长石的制造技术，具体是以丰富的硅酸盐矿物和化工原料等为组分原料，参照天然透锂长石化学计量值范围，借鉴陶瓷生产工艺流程和技术手段，用以合成特定硅酸盐矿物晶体的技术方案。该合成产物四方晶系透锂长石，是单斜晶系天然透锂长石的同分异构体，该产物在含锂品位、热负膨胀性能、材料纯净度等诸方面都优于天然透锂长石。同时，其生产制造成本也比进口透锂长石的市销价格更低亷，对于突破天然透锂长石资源瓶颈约束，拓宽耐热陶瓷原料供应来源，提高日用耐热陶瓷制品品质，皆具有积极而深远的意义。
