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℃

Application
1. Molybdenum heat shields are used in high-temperature and
sapphire growth furnaces due to their ability to withstand high
temperatures and corrosion.
2. Heat parts have high density, precise measurement, and smooth
surfaces, making them excellent for improving crystal pulling.
3. Heaters are made of Molybdenum, Tungsten, and its alloy
materials, which is widely used in high-temperature furnace, vacuum
furnace of ceramic, metallurgy, electronics, glass, and refractory
materials industries.
