| 简介 |
The present invention refers to barium titanate particles (core) by an additive on the surface of core-shell is coated with or more additives (core-shell) transition metal compound which forms precipitate water-additives composite-particles and relates to manufacturing method. Additive for example yttrium, manganese, zinc, cobalt, vanadium and chromium including transition metal; and magnesium, strontium and calcium-earth metal that including a metal selected from the group consisting of. metallic compound film, i.e., tungsten including. Said oxide material and metal metal metal compound includes carbon dioxide is applied to the. Furthermore, of the present invention manufacturing method as or different from the surface a titanium yttrium barium particle insoluble compound additive sludge surface barium titanate outside the upper and lower cases precipitation involves coating.. Barium titanate-of the present invention various composite particle additive information communication applications, e.g. MLCC (multilayer ceramic capacitors; laminated ceramic capacitor) application can be used in the field of the dielectric material which can be applied to the. |
