PRODUCTION OF DIELECTRIC PORCELAIN COMPOSITION |
摘要 |
PURPOSE:To obtain a dielectric porcelain composition having stabilized electrical characteristics bv using Mg(OH)2 and WO3 and initiating mechanochemical reaction in wet mixing the raw materials in producing a lead-based complex perovskite structural composition containing lead magnesium.tungstate as a component. CONSTITUTION:Magnesium hydroxide and tungsten oxide are used in producing a lead-based complex perovskite structural composition containing lead magnesium.tungstate [Pb(Mg1/2W1/2)O3] as a component. Mechanochemical reaction is initiated in wet mixing the raw materials to produce magnesium tungstate [MgWO4]. |
