Dense Magnesium oxide ceramics
Magnesium oxide ceramics made by adding yttrium oxide to magnesium oxide to make it denser. (Made by Tateho Ozark.)
Dense Magnesium oxide ceramics (Made by TOTC)
Features
The magnesium oxide is used as a refractory under severe condition because its melting point (3098K) is the highest in the oxide. The magnesium oxide is superior in corrosion resistance in the molten metal. The magnesium oxide can be used for a lot of metals compared with the aluminum oxide.
High densification
This product has a high densification quality due to the addition of yttrium oxide.
Inexpensive
We offer affordable prices.
Usage
Crucibles for metal melting
Tools for Sintering Ceramics.
Alternatives to Aluminum Oxide Ceramics
These products can be used for heat treatment of nickel alloys, plutonium/uranium refining, superconductor materials, piezoelectric materials, and lead materials.
They can be used in high temperature environments up to 2200°C.
