About: Borate glass

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Borate glasses have a more complex action of alkali ions than silicate glasses. Borate glasses also have major differences in their optical properties. The single largest use of boron compounds in the world (accounting for half of total global use) is the production of certain types of boron-treated glass fiber for insulating and structural fiberglass. In these uses the boron may be present as borax or boron oxide, and adds to the structural strength of the glass as borosilicate, or is added as a fluxing agent to decrease the melting temperature of pure silica, which is difficult to extrude as fibers and work with in pure form, due to the high temperatures involved.

dbo:abstract
  • Els vidres de borat tenen una acció més complexa d'ions alcalins que els vidres de silicat. Els vidres de borat també presenten diferències importants en les seves propietats òptiques. El principal ús individual de compostos de bor en el món (que representa la meitat de l'ús global total) és la producció de certs tipus de fibra de vidre tractada amb bor per a plàstic reforçat amb fibra de vidre aïllant i estructural. En aquests usos, el bor pot estar present com a bòrax o òxid de bor, i s'afegeix a la força estructural del vidre com a borosilicat, o s'agrega com a agent de flux per disminuir la temperatura de fusió del sílice pur, que és difícil d'extreure com a fibres i treballar en forma pura, a causa de les altes temperatures que comporta.
