Calcite and aragonite are formed by homogeneous precipitation method utilized hydrolysis of urea. Calcite is formed by agitating the reaction solution, aragonite is formed by without agitating the reaction solution. But, the yield of them were about 40%. Then, the formation area with addition of hydrogen peroxide and glutamic acid were investigated. As a result, calcite and aragonite were obtained with more than 90% yield by adding a hydrogen peroxide. Vaterite was obtained with more than 90% yield by adding hydrogen peroxide and gultamate.
