Factory Direct Price High Porosity Heat Insulation Refractory Light Weight alumina silica refractory Brick
Lightweight clay brick is made of high purity fire clay, by adding combustible, gas evolution method, or foam method.Lightweight clay brick is a kind of porous material with Al2O3 content 30-46%. Its refractoriness is 1580-1750 °C, refractoriness under load is 1250-1450 °C, with good thermal resistance and strong ability to resistant acid slag.The bulk density is 0.75-1.2g/cm3, crushing strength is 2.0-5.9MPa, thermal conductivity is 0.221-0.442W/(m.K) (1350°C)
Feature:
1.Low levels of iron and other impurities
2.High refractoriness,but can not contact with the flame directly
3.High porosity, low volume density, low thermal conductivity
4.Good heat insulating effect and energy-efficient
5.Good thermal shock stability.
6.Corrosion and erosion resistance
7.Long service life
