Baked porcelain powder for all-ceramic false tooth and preparation method of baked porcelain powder
The baked porcelain powder for the all-porcelain false tooth has a core-shell structure, a core layer of the baked porcelain powder comprises the following components in parts by mole: 0.5-3 parts of a potassium compound, 0.5-3 parts of an aluminum compound and 1-6 parts of tetraethoxysilane, and a shell layer of the baked porcelain powder comprises the following components in parts by mole: 70-85 parts of silica sol, 3-9 parts of the aluminum compound, 2-8 parts of the potassium compound, 2-7 parts of a sodium compound, 1-4 parts of boric acid, 0.3-3 parts of a calcium compound and 0-2 parts of a zinc compound. 0-2 parts of a magnesium compound and 0-1 part of a barium compound. The preparation method comprises the following steps: dissolving raw materials of a core layer in absolute ethyl alcohol, drying, calcining, cooling, and ball-milling to obtain KAlSi2O6 powder; and dissolving the raw materials of the shell layer in deionized water, then adding the KAlSi2O6 powder, carrying out ball-milling mixing, carrying out spray drying, carrying out high-temperature calcination, cooling, and crushing to obtain the baked porcelain powder for the all-porcelain false tooth. The porcelain powder provided by the invention has good jade texture and high strength.
本发明的一种全瓷义齿用烤瓷粉具有核‑壳结构，其核层的摩尔份数组成为：钾的化合物0.5～3份，铝的化合物0.5～3份，正硅酸乙酯1～6份，其壳层的摩尔份数组成为：硅溶胶70～85份，铝的化合物3～9份，钾的化合物2～8份，钠的化合物2～7份，硼酸1～4份，钙的化合物0.3～3份，锌的化合物0～2份，镁的化合物0～2份，钡的化合物0～1份。制备过程如下：将核层的原材料溶解于无水乙醇中，干燥后进行煅烧，冷却后球磨获得KAlSi2O6粉体；同时将壳层的原材料溶解于去离子水中，随后加入上述KAlSi2O6粉体进行球磨混合，再经过喷雾干燥后进行高温煅烧，冷却后粉碎即获得本发明的全瓷义齿用烤瓷粉。本发明的烤瓷粉具有良好的玉质感、强度高。
