About silicon carbide crucible for sale
Wiki Article
High alumina bricks represent a specialized class of refractory resources engineered to withstand Excessive temperatures exceeding 1,790°C while sustaining structural integrity and chemical steadiness. These bricks possess high refractoriness, superb thermal shock resistance, and superior mechanical toughness, generating them ideal for withstanding Extraordinary temperatures and harsh functioning ailments. The basic attribute that distinguishes high alumina bricks from standard fire bricks lies within their elevated alumina (Al2O3) material, typically ranging from forty five% to 90%, which specifically correlates with their enhanced efficiency abilities.
High alumina brick refractories may have two bond systems, ceramic, and phosphate. Phosphate brick is quickly acknowledged by a phosphorus pentoxide (P2O5) content on their data sheet of concerning about 3% and six%.
