Embodiment Construction

[0259] The glasses of Inventive Examples 1-6 provided in Table I were prepared by providing a mixture comprising 65-72 wt % perlite, 0-22 wt % dolomite, 6-35 wt % limestone and 0-8 wt % soda combination. The specific amounts of perlite, dolomite, limestone, and / or soda used to prepare Examples 1-6 were determined by reference to the compositional parameters of each mineral relative to the desired compositional parameters for each glass composition. The mixture of minerals is then heated to a temperature of about 1400° C. to obtain a molten glass composition. The molten glass compositions were cooled to provide the glass compositions of Examples 1-6.

Abstract

Some embodiments of the present invention provide fiberizable glass compositions formed from batch compositions comprising amounts of one or more glassy minerals, including perlite and / or pumice. Someembodiments of the present invention related to glass fibers formed from such batch compositions, and composites and other materials incorporating such glass fibers.

Description

[0001] Cross References to Related Applications [0002] This application is a divisional application of Chinese patent application 201380013694.6. This application claims priority to U.S. Provisional Application Serial No. 61 / 594,426, filed February 3, 2012, which is also U.S. Patent Application Serial No., filed February 3, 2012 Continuation-in-Part of U.S. Patent Application Serial No. 12 / 534,490 filed August 3, 2009, each of the above-mentioned patents It is hereby incorporated by reference as if set forth in its entirety. field of invention [0003] The present invention relates to glass compositions, and in particular to glass compositions for forming fibers. Background of the invention [0004] Large-scale commercial production of continuous glass fibers (E-glass and C-glass) involves the melting of batches consisting primarily of crystalline or substantially crystalline minerals. The transformation of these crystalline raw materials into the glassy state requires ...
