Calcium carbonate sintered body and method for producing same, and bone grafting material
The invention provides a method for producing a calcium carbonate sintered body, whereby it becomes possible to produce a satisfactory sintered body without the need to use a sintering aid. The method comprises the steps of: compression-molding calcium carbonate to produce a molded article; heating the molded article under the condition having a temperature of 500 DEG C or lower to remove organic components contained in the molded article; and sintering the molded article under the conditions having a carbon dioxide gas atmosphere and a temperature of 450 DEG C or higher to produce a calcium carbonate sintered body.
本发明提供一种不使用烧结助剂也能够得到良好的烧结体的碳酸钙烧结体的制造方法。该方法的特征在于，包括：将碳酸钙压缩成型，制造成型体的工序；通过在温度500℃以下的条件下对上述成型体进行加热，除去上述成型体中所含的有机成分的工序；和通过在碳酸气气氛且温度450℃以上的条件下将上述成型体烧结，得到碳酸钙烧结体的工序。
