Determination of boron (III) oxide in refractory products - Determination of total boron (III) oxide in oxidic materials for ceramics, glass and glazes Ingestion-build-126766 Mesh eye and face protectors1 Scope This part of ISO 21078 specifies methods of determining boron(III) oxide in refractory products and raw materials, in mass fractions of 0,01 % or greater. It is applicable to the determination of total boron(III) oxide in oxidic materials for ceramics, glass and glazes. The determination of boron(III) oxide is carried out using one of the following four methods: a) alkaline titrimetry, which is applied to samples containing more than 0,5 % by
