Product Description
Product Overview
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. Has
good insulating properties.
Product Features
1. High-purity magnesium oxide 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, thorium,
uranium, tin, lead, zinc, copper, cobalt and their alloys. 2. As a container for fused alumina and
aluminum salts.
3. The thermocouple protection tube made of magnesium oxide is used to measure the high temperature
above 2000ºC.
