White fused alumina 0-1mm 1-3mm 3-5mm 200F 325F for Refractory ramming mix
white fused alumina with complete specifications including 0-1mm, 1-3mm, 3-5mm granular aggregates and 200F, 325F fine powders is a high-purity refractory raw material exclusively formulated for refractory ramming mix, castables and high-temperature furnace linings. Manufactured from high-purity alumina powder via ultra-high temperature electric melting, precise crushing, screening and impurity removal processes, this white fused alumina features high refractoriness, low impurity content, excellent thermal stability and superior mechanical strength. It is an essential aggregate and fine filler for manufacturing high-performance refractory ramming materials.
