Calcined alumina powder
Calcined alumina powder is widely used in monolithic refractory and high grade fine ceramic industry which optimize the performance of the product.
The series of reactive Alumina powder have properties like high rate of activity, micro grain size, and complete phase transformation etc.
Reactive Alumina powder is the fundamental components of high quality refractory products like fine ceramics and castable refractories.
Benefits of using Reactive Alumina:
