  • Burners for producing boules of fused silica glass
    Patent number: 6751987
    Abstract: 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.

  • Methods for producing fused silica glass
    Patent number: 6532767
    Abstract: Methods for producing high purity fused silica (HPFS) glass having desired levels of dissolved hydrogen are provided. The methods involve measuring the level of hydrogen in the cavity of the furnace used to produce the glass and controlling the pressure within the furnace and/or gas flows to the furnace's burners so that the measured concentration has a desired value. In this way, the level of dissolved hydrogen in the glass can be controlled since, as shown in FIG. 3, there is a direct correlation between the hydrogen concentration in the cavity atmosphere and level of dissolved hydrogen in the glass.

  • Method and apparatus for preventing burner-hole build-up in fused silica processes
    Patent number: 6367288
    Abstract: In furnaces for producing high purity fused silica glass boules, glass particles have a tendency to build-up adjacent the burner hole rim. It was discovered that unburned furnace gases containing silica particles where re-circulated in the furnace close to the burner hole rim and reacted with the oxygen of infiltrated air adjacent the burner hole, and thus deposited such particles in the form of a glassy build-up about the rim of the burner hole. In order to eliminate the source of oxygen adjacent the burner hole rim, a curtain of an inert gas is caused to flow through the burner hole between the sidewalls of the burner hole and the flame of the burner. Accordingly, the curtain of inert gas inhibits the combustion of the unburned hydrogen and carbon monoxide furnace gases adjacent the exit rim of the burner hole and thereby minimizes glass build-up about the burner hole rim.
