Product Description

Refractory ceramic setter plates, high-tech products, are technical supporting parts for the high temperature furnace sintering. With the ceramic setter plates, the sintered products will be heated evenly. That will reduce energy consumption and accelerate sintering speed, improve yields

 

Product Feture:

* High corrosion-resistance.

* High mechanical strength.

* Lower possibility of crack by thermal shock.

* Longer service time

 

Properties of Alumina

Alumina has a high melting point, high hardness and high mechanical strength, although mechanical strength is reduced at temperatures above 1000°C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity.Good chemical stability of alumina, leads to a high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solution.
