Silicon Carbon SiC Refractory Brick for Creamic Kiln
The Description:
High alumina silicon carbidebrick (High Alumina silicon carbidebrick) refers to high alumina vanadium clay and silicon carbide as the main raw materials made of refractory products. It has high refractoriness and good thermal conductivity, and also has high high temperature strength and thermal shock resistance. The physical and chemical properties of high aluminum silicon carbide brick (for example) are as follows: Al2O3 70.88%, SiCl 0.78%, apparent porosity 20.4%, bulk density 3.3g/cm3, normal temperature compressive strength 54.3MPa, load softening starting temperature 1640ºC, refractoriness greater than 1770ºC.
