HIGH-PURITY CALCIUM CARBONATE SINTERED BODY AND PRODUCTION METHOD THEREOF, AND HIGH-PURITY CALCIUM CARBONATE POROUS SINTERED BODY AND PRODUCTION METHOD THEREOF

摘要

A high-purity calcium carbonate sintered body, and a production method thereof, with low impurity content and serviceable in biological applications, and a high-purity calcium carbonate porous sintered body, and a production method thereof, with low impurity content and serviceable in biological applications are provided. The production method of the high-purity calcium carbonate sintered body is characterized by involving a step for compression molding calcium carbonate that has a purity of at least 99.7 mass% to produce a molded body, and a step for producing a calcium carbonate sintered body by sintering the molded body. The production method of the high-purity calcium carbonate porous sintered body is characterized by involving a step for preparing a dispersion liquid containing calcium carbonate that has a purity of at least 99.7 mass%, a step for producing a foam by adding a foaming agent to the dispersion liquid and then agitating the dispersion liquid to a foam, and a step for producing a calcium carbonate porous sintered body by sintering the foam.
