aragonite powder

Original Research Article Merit Research Journals

Aragonite type of shell powder created by firing bivalve Corbicula japonica shell at 200 0 C for 40min was provided for the bio-activity studies using the alcohol-fed C57BL/6 mice model. Solubility of the aragonite shell powder in 1/10 N acetic acid was 85% and that of non-fired shell powder was 70%.
