Abstract
Official abstract text for this publication.
An object is to provide a method for manufacturing a calcium carbonate block of no less than 0.1 cm in diameter and thickness, not including any impurities, and able to be employed as a raw material of an artificial bone that requires biosafety: the method includes: (a) shaping a calcium hydroxide block; (b) being exposed to carbon dioxide; and (c) immersing in a carbonate ion containing solution.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a calcium carbonate block comprising: (a) shaping a block of calcium hydroxide; (b) exposing the block to carbon dioxide gas; (c) immersing the block in a solution containing carbonate ions; and after the immersing step, washing with water and drying the block, wherein all of the calcium hydroxide of the block is converted to calcium carbonate after the drying. 2. The method for manufacturing a calcium carbonate block according to claim 1 , the method further comprising: (d) mixing a pore-forming substance; and (e) forming a pore.
