Properties and characteristics of aluminum silicon carbide bricks
High alumina silicon carbide brick (high alumina silicon carbide brick) refers to a refractory product made of high alumina vanadium clay and silicon carbide as the main raw materials. It has high refractoriness and good thermal conductivity, as well as high high temperature strength and thermal shock resistance. The physical and chemical properties of high-alumina silicon carbide bricks (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 start temperature 1640 ℃, refractory degree greater than 1770℃.
