(EN) COMPOSITE OF CALCIUM CARBONATE FINE PARTICLE AND FIBER, AND PRODUCTION METHOD THEREOF
(JA) 炭酸カルシウム微粒子と繊維との複合体、および、その製造方法
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a technique for producing a composition of a calcium carbonate particle having average primary particle diameter of less than 1 μm and a fiber.

SOLUTION: The calcium carbonate is synthesized under the presence of cavitation air in a solution including a fiber, so a composite of the calcium carbonate fine particle having average particle diameter of less than 1 μm and the fiber can be efficiently synthesized.
