Raw material for producing basalt fibers

摘要

The invention relates to a raw material charge for a melt for producing continuous mineral fibers, containing 30% to 70% basalt and/or diabase, 8% to 40% quartz components, in particular quartz sand, and 5% to 30% slag, in particular blast furnace slag, the use thereof and a method of producing continuous mineral fibers from a melt, the melt being formed from raw material comprising 30% to 70% basalt and/or diabase, 8% to 40% quartz components, in particular quartz sand, and 5% to 30% slag, in particular blast furnace slag.
