Heat Shield used in Sapphire thermal field
Xi'an Refra Tungsten & Molybdenum Co.,Ltd is one of the best China heat shield
manufacturers and suppliers, and as a professional company we have our own productive
heat shield factory, welcome to wholesale products from us.
Relative to other materials, tungsten & molybdenum used as heat shield have the
characteristics of low vitalization in high temperature,less pollution to crystal, furnace clean,
long service life, not easy to deformation and so on, so it is widely applied in sapphire thermal field.
REFRA will take in design concept of high temperature furnace and apply this concept in sapphire
thermal field. Heat shield has advantages of free expansion in high temperature, strong
resistance to deformation, so relatively with long service life.
