摘要： Burners (14) are used to make glass bodies (19) from OMCTS. The burners have six concentric regions. Putting certain gases through the regions results in thicker bodies than can be achieved with existing techniques and with improved efficiency.

摘要： A method of producing, by flame hydrolysis, a fused silica glass containing titania which comprises delivering a mixture of a silica precursor and a titania precursor in vapor form to a flame, passing the vapor mixture through the flame to form SiO2-TiO2 particles, and depositing the particles within a furnace (40) where they melt to form a solid glass body (44).

摘要： A method for preparing high-purity, bulk fused silica includes supplying silane gas (11), a gaseous fuel (8), and oxygen gas (10B) to a combustion burner (14). A fuel and oxygen mixture (13) is produces when fuel (8) and oxygen gas (10A) in a premixing chamber (12). Nitrogen gas (17A) may also be supplied to the burner (14) which is located in the crown (16) of a furnace (15). Silica particles are formed by passing the silane gas into a flame formed by the combustion reaction of the gaseous fuel with the oxygen gas while maintaining the ratio of the flow rate of the gaseous fuel to the flow rate of the silane gas no less than twelve and the ratio of the flow rate of the gaseous fuel to the flow rate of the oxygen gas no less than three. Silane flow rates are controlled with a mass flow controller (51) and the flow of other gasses is monitored with flow meters (49). The silica particles formed are immediately deposited onto a hot bait (18) inside a containment vessel (21) to form a boule (19).

摘要： A method of protecting a metal (12) against embrittlement when the metal (12) is exposed to carbon or sulfur at an elevated temperature, the method comprising forming a thin, adherent, continuous coating (14) of a glass on the surface of the metal (12) prior to exposure to carbon or sulfur at an elevated temperature.

摘要： An article of relatively pure silica, and a furnace and method of producing the article. The article is produced by collecting molten silica particles (24) in a refractory furnace in which at least a portion of the refractory has been exposed to a halogen-containing gas to react with contaminating metal ions in the refractory.
