Abstract
The present invention aims to provide techniques for preparing complexes of calcium carbonate particles having an average primary particle size of less than 1 μm and a fiber.Complexes of calcium carbonate microparticles having an average primary particle size of less than 1 μm and a fiber can be synthesized efficiently by synthesizing calcium carbonate in a solution bearing the fiber while injecting a liquid into a reaction vessel.
