The light scattering properties and high refractive index of these intermediate calcined aluminas ARZ and AFRZ, make them ideal for opacifying in superwhite body, engobes and glazes.


Special reactive alumina gives opacification and replaces, completely or partially, zircon sand in formulation to give whiteness and opacification.
Ground alumina AFRZ can be used as a whitening agent when added after the milling of the body to obtain the best whiteness.
