Full title and description

St ISO 17947-2014 — Fine ceramics (advanced ceramics, advanced technical ceramics) — Methods for chemical analysis of fine silicon nitride powders. This International Standard specifies standardized procedures for chemical analysis of fine silicon nitride (Si3N4) powders used as raw material for advanced ceramics, including methods for preparation, blank testing and determination of total Si, total N and selected impurities.

Abstract

This document specifies methods for the chemical analysis of fine silicon nitride powders. It defines determination procedures for total silicon, total nitrogen, aluminium, iron, calcium, oxygen, carbon, fluorine and chlorine in such powders, using appropriate wet-chemical and instrumental techniques (for example XRF, combustion and carrier‑gas hot extraction where referenced).

Scope

ISO 17947:2014 applies to the chemical analysis of fine silicon nitride powders used as raw materials for fine/advanced ceramics. It specifies methods to determine total silicon and nitrogen and to quantify common contaminant elements and non‑metallic impurities (Al, Fe, Ca, O, C, F, Cl) relevant to powder quality and ceramic processing. The procedures are intended for use in quality control, incoming inspection and laboratory analysis where accurate composition data influence sintering and final properties.

Key topics and requirements

• Defined analytes and reporting requirements: total Si, total N, Al, Fe, Ca, O, C, F, Cl and related impurity limits and expression of results.
• Sample preparation and blank-test procedures to ensure representative and traceable analysis of fine powders.
• Recommended analytical techniques (examples referenced): wet chemical methods, X‑ray fluorescence (XRF — fused bead), carrier‑gas hot extraction (CGHE), combustion analysis and other validated instrumental methods.
• Precision, reproducibility and method validation guidance appropriate for laboratory quality control and supplier certification.

These topics are summarised from the standard text and from accompanying committee descriptions of the standard’s scope and technical content.

Typical use and users

Typical users include materials scientists, analytical and testing laboratories, powder manufacturers and ceramic component producers. Common uses are incoming raw‑material inspection, supplier certification, process control, R&D and failure analysis where chemical composition (Si/N balance, oxygen/carbon contamination, trace metals) affects sintering behaviour and final mechanical properties.

Related standards

ISO 17947:2014 was developed under ISO/TC 206 (Fine ceramics) and references related analytical and sampling standards. A draft / DIS labeled ISO/DIS 17947‑1 (Methods for chemical analysis of silicon nitride powders — Part 1: wet chemical methods, XRF fused bead, CGHE and combustion methods) has been prepared as a follow‑on; the ISO record indicates the standard is in the review/revision cycle. Related regional/adopted versions (EN/ISO, national adoptions) are also available.
