Testing of ceramic raw and basic materials - Chemical analysis of boron carbide, boron nitride, metal borides and elemental boron - Part 2: Determination of total boron, soluble boron compounds, HNO₃-soluble boron in B₄C, H₂O₂ soluble and insoluble fractions in amorphous boron and HF/HNO₃ insoluble fractions in titanium boride

Title (German)

Prüfung keramischer Roh- und Werkstoffe - Chemische Analyse von Borcarbid, Bornitrid, Metallboriden und elementarem Bor - Teil 2: Bestimmung von Gesamtbor, löslichen Borverbindungen, von HNO₃-löslichem Bor in B₄C, H₂O₂-löslichen und unlöslichen Anteilen in amorphem Bor und von HF/HNO₃-unlöslichen Anteilen in Titanborid

Overview

This Part 2 of the series of standards specifies the determination of total boron and various -acid or water-soluble forms of boron. A titrimetric and a spectrometric method are specified. For amorphous boron, a method is also specified for the determination of the parts insoluble in hydrogen peroxide and the boron soluble in hydrogen peroxide. Furthermore, for titanium boride a method for the determination of the HF/HNO insoluble fractions is specified. It applies to boron carbide, presented as coarse raw material, granular material or powder, as well as sintered and shaped boron carbide, amorphous boron and boron nitride in various degrees of purity as powder or shaped or hot-pressed bodies for the purpose of determining the various chemical constituents. This document also applies to the metal borides aluminum boride, calcium boride, chromium boride, lanthanum boride, magnesium boride, molybdenum boride, titanium boride, and zirconium boride, as well as other metal borides after substance-specific testing. This document has been prepared by Working Committee NA 062-02-64 AA "Chemische Analyse von nichtoxidischen keramischen Roh- und Werkstoffen" ("Chemical analysis of non-oxidic ceramic raw and basic materials") at DIN Standards Committee Materials Testing (NMP).
