Dense Low Porosity Anti-penetration Phosphate Brick

Dense Low Porosity Anti-penetration Phosphate Bonded Brick – Unfired High-Grade Bauxite Aggregate Refractory Block With Aluminum Phosphate Chemical Bond Matrix, Low Open Pore Dense Shaped Brick For Cement Kiln Coating Adhesion, Severe Thermal Cycle & Clinker Abrasion Working Zones 1. Product Core Profile This dense low porosity phosphate bonded brick belongs to chemical bonded unfired shaped refractory, forming an independent product category separated from high-temperature sintered Refractory Brick, common clay Firebrick, fused dense High-Temperature Brick, front anti-scouring Kiln Brick, decorative dense Ceramic Brick and porous lightweight Insulating Fire Brick. The raw material grading system adopts premium grade bauxite clinker as main rigid aggregate, matched with fine high-alumina mineral powder to optimize particle stacking density, and introduces industrial phosphate liquid as inorganic chemical bonding agent instead of traditional ceramic sintering binding phase.
