Beschreibung
Zusammenfassung:	The invention relates to shellfish shell calcined powder and a manufacturing method thereof. After shellfish shell particles are subjected to an alkali coating step and a calcining step, the obtained shellfish shell calcined powder has a core-shell structure, so that the whiteness and the antibacterial property can be effectively improved, and the heavy metal content can be reduced. 本发明有关于一种贝类外壳煅烧粉体及其制造方法，其对贝类外壳颗粒进行碱包覆步骤及煅烧步骤后，所得的贝类外壳煅烧粉体具有核壳结构，可有效提升白度及抗菌性并降低重金属含量。
