MgO magnesia stabilized yellow Zirconia Ceramic Parts
Reputation depends on quality, quality comes from Hard!
Zirocnia Ceramics:
Magnesium oxide stabilized Zirconia Ceramics, zirconia toughened ceramics prepared with magnesium oxide as a stabilizer. Cubic zirconia and metastable tetragonal zirconia ceramics can be prepared respectively according to the content of magnesium oxide stabilizer and the difference of preparation process. By controlling the nucleation growth of the Alumina Ceramic Bar tetragonal phase, a magnesia partially stabilized Zirconia Ceramic with the best flexural strength and fracture toughness can be obtained. Its application is roughly the same as that of yttria-stabilized zirconia ceramics. And more because of its unique thermal shock resistance. Widely used in metallurgy, steel and petrochemical industries. It can also be used to manufacture special ceramic cutting tools, standard measuring tools, mechanical seals, stamping dies and various wear-resistant parts in the mechanical and textile industry. Magnesium oxide ceramics belong to the cubic crystal system. Magnesium oxide ceramics have a large thermal expansion coefficient and a high vapor pressure. The melting point is 2800 °C, but it is volatile above 2300 °C; the specific volume resistance (35V/mm) at high temperature is large, with Good insulation. Magnesium oxide ceramics are typical alkaline ceramics. Magnesium oxide ceramics are generally yellow, and the operating temperature is higher than that of Alumina Ceramics. The operating temperature is as high as 2200°C in an oxidizing atmosphere, up to 1700°C in a reducing atmosphere, and can reach 1600-1700°C in a vacuum. In the air, Alumina Ceramic Plunger especially in humid air, magnesia ceramics are easily hydrated into industrial Mg(OH)2, and special attention should be paid to the manufacture of magnesia ceramics. High-purity magnesia ceramics have strong corrosion resistance to metals and alkaline solutions, and are used as crucibles for melting high-purity iron and alloys as well as nickel, Zirconia Ceramic Block thorium, uranium, tin, lead, zinc, copper, cobalt and their alloys; Containers for fused alumina and aluminium salts; thermocouple protection tubes made of magnesia for measuring high temperatures above 2000°C. Magnesium oxide ceramics can also be used for high temperature furnace lining.
