Magnesia Crucible
Magnesium oxide (Magnesia, MgO) crucible can be used in ultra-high temperature environments up to 2300°C (in vacuum). MgO crucibles are a better alternative to aluminum oxide (Al2O3) crucibles as they have excellent chemical resistance and are inert to metals, slags, and superconducting compounds.
MgO crucible content: 99% MgO. Edgetech can provide custom MgO crucibles upon request.

Properties of Magnesia Ceramics
-The melting point of magnesium oxide is as high as 2800℃, and it has strong corrosion resistance to metals and slag.
-Magnesium oxide does not react chemically when in contact with many metals. In an inert atmosphere, even at a temperature of up to 1800℃, magnesium oxide does not react with metals such as nickel, molybdenum, and niobium; under a vacuum of 0.1-0.5mmHg, the reaction temperature between magnesium oxide and carbon is 1800℃, and the reaction temperature between magnesium oxide and nickel is 2000℃
Applications of MgO Crucible
When the MgO crucible is used for lithium solid electrolyte synthesis or sintering, unlike the Al2O3 crucible, a magnesium oxide crucible is used, and short-term sintering is performed at high temperatures, which can effectively reduce the volatilization of lithium during high temperature and avoid the formation of secondary phases such as lanthanum zirconate.
Magnesium oxide has a high melting point and strong corrosion resistance, so it can be used as a metallurgical container in large quantities. It can smelt rare metals, zinc, copper, lead, platinum, diamond, and their alloys. Magnesium oxide can also be used as a mold for casting pure metals and a crucible for melting gold-boron alloys in semiconductor technology. Magnesium oxide crucibles use graphite as a conductor in induction furnaces or resistance furnaces and can be used at high temperatures of 2300-2400°C for short-term experiments. Magnesium oxide can be used to melt high-purity radioactive metals such as uranium and polonium and their alloys in high-frequency induction furnaces.
