摘要：
Provided is a method for producing a calcium carbonate sintered compact by which sintering can be done at a lower temperature and a higher-density calcium carbonate sintered compact can be produced. A method for producing a calcium carbonate sintered compact includes the steps of: preparing calcium carbonate and a sintering aid that is a mixture of potassium fluoride, lithium fluoride, and sodium fluoride and has a melting point of 600°C or less； compression molding a mixture of the calcium carbonate and the sintering aid mixed to contain the sintering aid in an amount of 0.1 to 3.0% by mass, thus making a green compact； and sintering the green compact to produce a calcium carbonate sintered compact.
