Lightweight clay tiles should have a high refractoriness

Lightweight clay brick to have a high refractoriness, can resist the role of high temperature heat load, do not soften, do not melt. Lightweight clay brick should have high strength and high temperature resistance strength, high load softening temperature, high creep resistance, can resist the common role of high temperature heat load, does not lose strength, does not occur creep and collapse. Lightweight clay brick should have good thermal shock resistance, slag resistance, high density, abrasion resistance, good impact resistance and chemical stability. Lightweight clay bricks have high volumetric stability, residual shrinkage and residual swelling are small, no crystal transition and severe volume effect, volume does not shrink and only uniform expansion.
