| 摘要 |
The invention concerns an iron poor mineral fibre having a high temperature resistance. The mineral fibre has the following composition in % by weight: SiO2 35 - 45, Al2O3 18 - 25, TiO2 0 - 3, MgO 12 - 20, CaO 10 - 20, Na2O + K2O 0 - 3, iron (Fe2O3+FeO) 0 - 3, B2O3 0 - 3, P2O5 0 - 4, other 0 - 3, whereby the sum of FeO + MgO >/= 15 % by weight.
