초록

The present invention relates generally to production of a fluoride gas and equivalents thereof, and fluorine-doped sodium silicate glass, glass ceramics, vitro ceramics and equivalents thereof. In one embodiment, the method includes providing a salt and an oxide in a reactor, heating the reactor to produce a vapor and the vitro ceramic and removing the vapor.

청구항

1. A method for producing sodium silicate glass during a production of a high purity silicon (Si), comprising: precipitating sodium fluorosilicate (Na2SiF6) from fluorosilicic acid (H2SiF6);thermally decomposing the Na2SiF6 to produce a silicon tetrafluoride gas (SiF4) and sodium fluoride (NaF);reducing the SiF4 with sodium (Na) to produce NaF and the high purity Si in a first reactor;providing the NaF from the reduction of the SiF4 from the first reactor and silica sand (SiO2) in a second reactor; andheating the second reactor to produce additional SiF4...
