| titleOfInvention | Porcelain powder and preparation method thereof |
| abstract | The invention belongs to the field of false tooth manufacturing, and particularly relates to porcelain powder and a preparation method thereof. The specific technical scheme is as follows: the porcelain powder has the following formula: 55 to 70 percent of SiO by mass percent 2 、10％～25％Al 2 O 3 、5％～30％K 2 O、1％～10％Na 2 O、0.1％～5％CaO、0.1％～5％BaO、0.1％～5％TiO 2 、0.1％～5％ZrO 2 、0.1％～5％Li 2 O、0.1％～5％SnO 2 、2％～10％B 2 O 3 、0.1％～5％MgO、0.01％～1％ZnO、0.01％～1％Y 2 O 3 0 to 0.1% of inorganic pigment, 0 to 0.1% of organic indicating pigment. The invention provides a brand-new method for preparing porcelain powder, which divides raw materials into two parts, respectively self-prepares two main types of raw materials required, and then respectively carries out treatment of different methods according to respective characteristics, thereby finally effectively improving the precision, fineness, biocompatibility and mechanical property of the prepared porcelain powder and perfectly matching with a zirconia substrate. |
