polished abrasive ZrO2 Zirconia Ceramic Tube plunger pipe
Reputation depends on quality, quality comes from Hard!
Zirocnia Ceramics:
Pure zirconium dioxide will undergo t-m phase transition, which will easily lead to product fragmentation and lose practical value. Therefore, in the production process, Y2O3, CeO2, CaO and MgO are commonly used to stabilize the treatment of Zirconia Ceramics. The principle is to introduce Zr4+ by replacing these metal ions Y3+, Ca2+, Mg2+, Ce2+, etc. in the crystal structure of zirconia to form a solid solution, so that the tetragonal zirconia can be kept at room temperature without phase change, thereby stabilizing oxidation. Zirconium ceramic material. Zirconia ceramics have high hardness, high wear resistance, good high temperature thermal stability and thermal shock resistance. The preparation of high performance zirconia ceramics relies on high quality zirconia powders and optimized sintering process parameters. But from another point of view, people use a stabilizer and some specific processes to control the martensitic transformation of zirconia, and obtain metastable tetragonal zirconia sensitive to external stress at room temperature to produce a phase change. High-toughness Zirconia Ceramic materials. The preparation methods of high-quality zirconia powder mainly include physical methods and chemical methods. Physical methods include high temperature spray pyrolysis, spray induced coupled plasma pyrolysis, and freeze drying. Chemical methods include gas phase methods, liquid phase methods, and solid phase methods. Among them, the liquid phase synthesis method has high efficiency, good powder particle quality and relatively simple equipment, and thus has been widely used.
