Abstract
We examined silica coating methods on Fe3O4 (black), FeOOH (yellow) an d Lithol Rubine BCA (RED) powders by means of atmospheric pressure glo w plasma CVD with tetraethoxysilane. These pigments were deteriorated easily by heating or oxidation. However, cooling the discharge tube an d depositing protective films on the pigments before plasma oxidation could prevent the deterioration. We developed three ways to make prote ctive films, which suited each pigment's characteristics. (C) 1998 Els evier Science S.A.
