Abstract:
In this paper,we investigated the purity of Talci Pulvis from four manufacturers,both qualitatively and quantitatively. Firstly,the property of Talci Pulvis from four manufactures was investigated by PXRD,SEM and FT-IR,and percentage composition of talci and magnesium in Talci Pulvis were determined by K-Value method of PXRD. The results showed that Talci Pulvis from four manufactures,all conform to the rules,and the Talci Pulvis from D manufacturer has superior quality,which provides a reference for the production enterprises to select Talci Pulvis according to the actual needs.
