PRODUCTION OF FINE POWDER OF CERAMIC RAW MATERIAL

摘要

PURPOSE:To obtain ceramic raw material fine powder having uniform and small particle diameter. CONSTITUTION:An aqueous solution (solution A) containing oxalic acid and titanium and/or zirconium is dripped into an aqueous solution (solution B) containing ammonium and mixed. The solution A and/or the solution B properly contains an alkaline earth metal and the prepared precipitate is dried and burnt to give ceramic raw material fine powder.
