ASTM B387 High Temperature Furnace Polishing Molybdenum Heat Shields
ASTM B387 Molybdenum Heat Shields For High Temp Furnace
Molybdenum Heat Shields can be used in air and various gas environments. The working temperature of the MoSi2 heating
element is 1300C to 1800C. It has the characteristics of high-temperature resistance, oxidation resistance, corrosion resistance, heating fast, long service life, high-temperature low distortion, easy installation and maintenance, excellent chemical stability
Introduction
The molybdenum heater and Tungsten heater are used as heat insulation components, which play an essential role in heat insulation and reflection in the sapphire growth furnace, tungsten, and molybdenum materials are the best choice for the high-temperature furnace heating elements as their High-density, high-temperature strength, accurate measurement, smooth surface, convenient assembly, and reasonable design of heat components are of great significance for improving the crystal pulling performance.
We suggest that the operating temperature of the heater is not more than 2,000℃
and the operating temperature of the Tungsten heating chamber is not more than 2,800℃
