Title: Methods for Production of vaterite type calcium carbonate by using oyster shell
IPC: C01F11/18
Filed: 2020-05-15
Abstract: In Korea, 300,000 tons or more of waste oyster shells are generated per year. A part of them is reused for oyster seeding/seed collection and as a raw material for fertilizer, and another part thereof is embedded in a garbage landfill. However, the remaining part thereof is filed up and left unattended. Therefore, development of a technology of converting oyster shells into resources is advantageous in that the cost required for waste disposal can be reduced and waste resources can be reused as useful resources. Calcium carbonate is present as amorphous calcium carbonate (ACC) in the early stage of reaction and is changed into the three crystal forms of calcite, aragonite and vaterite. Among the same, the most unstable crystals, i.e. vaterite-type crystals have the smallest crystal size of 1-25 micrometers and a circular shape to provide high dispersibility. In addition, the vaterite-type crystals include no crude aggregate, and thus are expected to provide the effects of improving coatability and packability when being used as fillers for plastics, paint or rubber and paper and can improve the physical strength, gloss, color developing property and printability of products. Therefore, the present invention provides a method for preparing vaterite-type calcium carbonate by using oyster shells through the addition of lysine in a process allowing stable acid-base contact.
