ISO 3180:2023
Fine ceramics (advanced ceramics, advanced technical ceramics) â Methods for chemical analysis of calcium-phosphate-based powders for non-biomedical applications
détails du produit
It stipulates the methods used for the determination of major elements of calcium-phosphate-based powders and their impurities. Calcium-phosphate-based powders are decomposed by acid decomposition. The calcium content is determined using a titration method or an ICPâOES method. The phosphorus content is determined using a precipitation and gravimetric method or an ICPâOES method. Certain impurities, such as aluminium, barium, chromium, copper, iron, magnesium, manganese, nickel, potassium, selenium, silicon, sodium, strontium, titanium and zinc contents, are determined by an ICPâOES method.
This document does not include calcium-phosphate-based powders for biomedical applications. The ISOÂ 13779 series characterizes hydroxyapatite powders for biomedical applications using various methods, such as atomic absorption spectrometry (AAS), inductively coupled plasmaâmass spectrometry (ICPâMS) and flame atomic absorption spectrometry (FAAS).
