针状碳酸锶微粒及其分散液
摘要：
本发明提供由微细的针状碳酸锶颗粒构成的针状碳酸锶粉末、以及微细的针状碳酸锶颗粒以一次颗粒或近似一次颗粒的微粒状态分散在有机溶剂中的分散液。由一次颗粒的平均长径处于5～50nm的范围、且长径比的平均值处于2.2～5.0的范围的针状碳酸锶颗粒构成的针状碳酸锶粉末、以及该针状碳酸锶颗粒的大部分以一次颗粒的形式分散在有机溶剂中的分散液，其中，优选在针状碳酸锶颗粒的表面附着有表面活性剂，所述表面活性剂包含亲水性基团和疏水性基团，还具有在水中形成阴离子的基团。
摘要（英）：

A powder of acicular strontium carbonate particles comprises primary particles having a mean longitudinal diameter in the range of 5 to 50 nm and a mean aspect ratio in the range of 2.2 to 5.0, and a dispersion liquid in which the powder of acicular strontium carbonate particles is dispersed in an organic solvent substantially in the form of primary particles; which preferably have a surface active agent having a hydrophilic group, a hydrophobic group and a group forming an anion in water attached to their surfaces.
