VITREOUS ARTIFICIAL FIBRE

Man-made vitreous fibres have a solubility at pH 4.5 of at least 20nm per day and a melt viscosity of 10-70 poise at 1,400°C. A composition which will provide these properties is selected for their manufacture and contains at least 105 by weight Al2O3. Novel fibres contain at least 6% by weight Na2O...

Zusammenfassung:	Man-made vitreous fibres have a solubility at pH 4.5 of at least 20nm per day and a melt viscosity of 10-70 poise at 1,400°C. A composition which will provide these properties is selected for their manufacture and contains at least 105 by weight Al2O3. Novel fibres contain at least 6% by weight Na2O + K2O.
