ABSTRACT:
The present invention concerns glass compositions capable of being attenuated in the form of fibers.
These glass fibers comprise the following oxides in the percentages by weight: SiO.sub.2 :37 to 48%; Al.sub.2 O.sub.3 :17 to 25%; CaO:23 to 33%; MgO:0.1 to 7%; Fe.sub.2 O.sub.3 :0.1 to 3%; Na.sub.2 O:2 to 8%; K.sub.2 O:0.1 to 7%, the sum of the percentages of earthalkaline oxides (CaO and MgO) being less than or equal to 34%, and the sum of the alkaline oxides (Na.sub.2 O and K.sub.2 O) being greater than 5%.
The invention is applicable to the manufacture of products subjected to elevated temperatures, for instance, products used for insulation purposes, even when such products may be subjected to a temperature as high as 700.degree. C.
