Abstract:
Processes and systems for producing glass fibers having regions devoid of glass using submerged combustion melters, including feeding a vitrifiable feed material into a feed inlet of a melting zone of a melter vessel, and heating the vitrifiable material with at least one burner directing combustion products of an oxidant and a first fuel into the melting zone under a level of the molten material in the zone. One or more of the burners is configured to impart heat and turbulence to the molten material, producing a turbulent molten material comprising a plurality of bubbles suspended in the molten material, the bubbles comprising at least some of the combustion products, and optionally other gas species introduced by the burners. The molten material and bubbles are drawn through a bushing fluidly connected to a forehearth to produce a glass fiber comprising a plurality of interior regions substantially devoid of glass.

Abstract:
This invention relates to a glass-ceramic material and its production method wherein glass ceramics having low expansion coefficient are produced ecologically and whereby said method comprises the steps of raw material batch preparation (101), melting (102), batch compensation to final composition (103), refining of the gas bubbles (104), shaping process (105) and ceramization (106). Preferably, the glass-ceramic comprises in wt %: 60-70 SiO2, 15-25 AI2O3, 0.5-5 B2O3, 3-8 Li2O, 0.5-2 Na2O, 0.1-0.8 K2O, 0.1-1.5 BaO, 0-0.5 CaO, 1-2.5 ZnO, 1-4 TiO2, 1-4 ZrO2, 0.1-2.5 P2O5, 0-0.5 MgO. The batch compensation step (103) consists in adding 0.5-5 wt % B2O3 and 0.1-2.5 wt % P2O5 during the melting process (102). Instead of oxide raw materials, carbonates (e.g. Li2CO3), nitrates (e.g. KNO3), or sulphates are used.
