Introduction:

Dental zirconia granulation powder RYK1 is a promising dental all ceramic material. With the increasing aesthetic requirements of people, the aesthetic and durable all-ceramic dental restorations have attracted much attention. In the past, the application of all-ceramic materials was limited because of its brittleness, beauty and safety. The dental zirconia granulated powder produced by our company is called ductile ceramics because of its stress-induced transformation toughening property. It is a new all-ceramic material superior to alumina because of its high strength and good biocompatibility.

3mo1 yttria stabilized tetragonal zirconia granulated powder VK-RYK1 is the most widely used biomedical material at present. 3mo1 Yttrium stabilized zirconia granulation powder RYK1B is a product with an additive, which is very suitable for mechanical pressing and isostatic pressing molding, so that users can save the trouble of adding adhesive.

Compared with traditional dental ceramics, the tetragonal zirconia granulated powder (t-ZrO2) polycrystalline ceramics (Y-TZP) with yttria (Y2O3) as stabilizer has been widely concerned for its high toughness due to the stress-induced phase transformation toughening of metastable tetragonal zirconia synclinal zirconia (m-ZrO2). Dental zirconia granulation powder is an excellent high-tech biomaterial.
