Industrial Ceramics
BSC Engineering Solution supplies high-performance Alumina Ceramic seal faces, available in 95% to 99% Alumina grades, engineered for use in chemical plant sealing applications and other environments where corrosive chemical attack is severe. These ceramic seal parts are designed for high durability and precision, making them ideal for mechanical seals, pumps, and process equipment in aggressive operating conditions.
Our alumina ceramic materials undergo rigorous laboratory testing to evaluate resistance to various chemicals and their impact on surface integrity. Results show exceptional acid resistance, with material stability rated within 0–10 mg/cm². This makes alumina ceramic seal faces a reliable solution for long-term performance in chemical processing, pharmaceutical, and petrochemical industries.
