LACfire 1550/30 1450 °C

Combined mullite refractory concrete with the addition of silicon carbide to increase hardness. Shaped blocks made of this refractory concrete material excel in their strength, small linear changes, and resistance to abrasion. Because of this, they are often used in combustion boilers fed with alternative fuels such as wood pellets, wood chips, and biomass.

I want shaped blocks made from this mixture
