The theoretical melting point of magnesium oxide ceramics is as high as 2800 degree C , and it can work stably to 2400 degree C under the protection of oxidizing atmosphere or nitrogen. Moreover, it has strong resistance to alkali metal slag, has excellent thermochemical properties and stability against metals, and is especially suitable for some harsh occasions where ceramic materials such as alumina with high temperature and alkaline corrosive substances are difficult to meet the conditions, such as smelting non-ferrous metals and precious metals, it can also be used to smelt high-purity radioactive metal uranium, thorium alloy, iron and its alloys.
The high-purity, high-density magnesium oxide high-temperature corrosion-resistant ceramics produced by our company have a theoretical use temperature of 2200 degree C and can be used for a long time at high temperatures of 1600 ~ 1800 degree C. Its high temperature stability and corrosion resistance are better than alumina ceramics, and its target applications include:
1. Crucibles or other refractory materials under corrosive conditions in steel, glass and other smelting industries. The operating conditions of the steelmaking industry are very harsh: the operating temperature is between 1500 and 1700 degree C, and there is corrosion of molten metal, slag, iron oxide, dust and gas. The conditions of the glass industry and the steelmaking industry are equivalent: the operating temperature is between 1100 and 1700 degree C.
2. Crucibles for smelting metals and alloys, such as nickel alloy, radioactive metal uranium, thorium alloy, iron and its alloys, etc.
3. Piezoelectric, superconducting materials, etc., no pollution, lead corrosion resistance, etc.
4. Ceramic sintered carrier. Especially for the sintering protection of ceramic products with corrosive and volatile substances at high temperatures such as β-Al2O3.
