    摘要: An acicular strontium carbonate fine powder having a mean length of 150 nm or less and a mean aspect ratio of 1.5 or more and containing acicular strontium carbonate particles having a length of 200 nm or more in an amount of 5% or less in terms of number of acicular particles is improved in its dispersibility in hydrophobic organic solvent by treating the acicular strontium carbonate fine powder with a combination of polycarboxylic acid having a side chain of a polyoxyalkylene group or its anhydride and amine having a polyoxyalkylene group and a hydrocarbyl group.
