Boron oxide is a crucial component of special glasses. On account of boron’s low atomic weight the determination with the aid of XRF is merely possible with restrictions.
On demand we can offer the successive wet chemical methods:
Content ≤ 2,5 wt. % – Determination using ICP-OES from cold stirred digestion (accredited in-house method)
Content 2,5 wt.% < x < 15 wt.% – Determination using ICP-OES from melt digestion according to DIN EN ISO 21078-1:2008 (accredited method)
Content > 15 wt.% – Determination by titration from melt digestion according to DIN EN ISO 21078-1:2008 (accredited method)
