Aluminum calcium oxide

Aluminum calcium oxide (CAS 12042-68-1) is an inorganic mineral compound used across construction, water treatment, and metallurgical processing. It functions primarily as a binder, flocculant, and flux, depending on the application and grade.

In construction, it is the active phase in calcium aluminate cements, which deliver rapid strength gain and high-temperature resistance in refractory castables, industrial flooring, and sewer infrastructure.

Water treatment facilities use it as a coagulant and flocculant to remove suspended solids, phosphates, and turbidity from municipal and industrial effluents. It is essential for maintaining water quality standards.

In steelmaking and foundry operations, it acts as a slag conditioner and flux, improving melt fluidity and facilitating impurity removal during refining. This ensures high-quality metal production and efficiency.

Specialty refractory manufacturers also incorporate it into monolithic linings and kiln furniture formulations that must withstand sustained thermal cycling. Its durability makes it a preferred choice for extreme environments.

Aluminum calcium oxide is supplied as powder or granules, with particle size and alumina-to-calcium ratio varying by application. Established grades include technical and refractory grades for various industries.

Cement-grade material conforms to standards such as ASTM C1157 or equivalent. High-purity grades are available for demanding refractory and water treatment applications where consistent phase composition is critical.

These high-purity options ensure process performance and reliability in sensitive industrial systems. The material remains a versatile component in modern chemical engineering and infrastructure development.
