Reactive Grade Alumina (Al2O3)

 

Martinswerk reactive grade alumina powders are processed for use as a reactive binder in various applications. Technical ceramics, structural ceramics electronic substrates and refractory shapes. With a crystal size of less than 2 microns, the Martinswerk reactive grade alumina powders have an Al2O3 content of at least 99.7%. Reactive grades are more stable than calcined alumina, thus suitable for dense, high strength wear resistant materials
