    General

    A-42 series is the most general fine-particle alumina used for refractory and porcelain. A-420 has high compressed bulk density and high thermal reactivity, so dense sintered compact can be obtained. A-43 series of minute alumina is excellent in sintering activity and has 2 grades depending on ultimate crystal particle diameter.
