Amorphous Calcium Aluminate
Amorphous Calcium Aluminate is a non-crystalline calcium aluminate material characterized by excellent reactivity, fast hydration and high early-strength performance. Compared with crystalline calcium aluminate phases, its amorphous structure enables rapid dissolution and superior bonding behavior in demanding industrial applications.
Main Applications
Amorphous Calcium Aluminate is widely used in refractory materials, special cement systems, ceramic formulations, castable refractories, high-temperature coatings and metallurgical additives where fast strength development and chemical stability are required.
