Production formula of calcium-magnesium-salt-free high-aluminum ceramic granulation powder

QI ZHIYU

The invention discloses a production formula of calcium-magnesium-salt-free high-aluminum ceramic granulation powder. The formula consists of lanthanum oxide, strontium carbonate, kaolin, yttrium oxide, talcum powder, silicon dioxide and aluminum oxide. According to the production formula of calcium-magnesium-salt-free high-aluminum ceramic granulation powder, aiming at the phenomenon that the appearance and brittleness of a product are influenced by the cloud spot phenomenon, analysis and experiments are carried out and prove that the cloud spot phenomenon is caused by calcium and magnesium salts in the original formula, so that a calcium and magnesium salt-free formula is developed; and meanwhile, the brittleness problem is considered, and silicon dioxide, lanthanum oxide, strontium carbonate, yttrium oxide and talcum powder are added to improve the toughness of the product.

一种无钙镁盐高铝陶瓷造粒粉生产配方，配方由氧化镧、碳酸锶、高岭土、氧化钇、滑石粉、二氧化硅和氧化铝组成。本发明采用的无钙镁盐高铝陶瓷造粒粉生产配方，针对云斑现象，影响产品的美观及脆裂，经过分析和实验，云斑现象是因为原有配方中的钙镁盐引起的，因此研制出无钙镁盐配方，同时考虑脆裂的问题，增加了二氧化硅、氧化镧、碳酸锶、氧化钇、滑石粉，来改善产品的韧性。
