ALKALI TITANATE POWDER, ITS PRODUCTION, COMPOSITE MATERIAL CONTAINING THE POWDER AND PRODUCTION OF ALKALI TITANATE SINTERED COMPACT

摘要

PURPOSE: To obtain a globular alkali titanate powder by spray-drying a slurry obtained by adding the fine particle of a titanium source to an aq. soln. of an alkali source and sintering the dried material at a specified temp. ;CONSTITUTION: A titanium source having ≤1μm particle diameter is added to an aq. soln. of a water-soluble alkali source to prepare a slurry. The slurry is spray-dried and then sintered at 700-1200°C or the slurry is sprayed into an atmosphere at 700-1200°C and then sintered, and a globular alkali titanate powder having ≤1000μm particle diameter is obtained. A composite material using the powder with a thermoplastic or thermosetting resin as a matrix is formed, a composite material such as frictional material, paint and cosmetic using the powder is formed, and both materials exhibits an excellent characteristic.;COPYRIGHT: (C)1995,JPO
