    • The green reflection color of back surface mirrors produced by deposition of a reflecting layer over two reflection enhancing layers on a glass substrate is controlled by selection of the layer materials and thicknesses to provide a reflection color having an a* value greater than -6, with a light reflection of at least 65%, preferably at least 70%. The inner reflection enhancing layer and reflecting layer are preferably of silicon, with the inner reflection enhancing layer having an optical thickness less than 125 nm; the intermediate reflection enhancing layer, which may be of silicon oxide, preferably has an optical thickness greater than 125 nm. The mirror may be produced by depositing the successive layers on a hot ribbon of glass during the glass production process.
    • 通过选择层材料和厚度来控制通过在玻璃基板上的两个反射增强层上沉积反射层产生的背面反射镜的绿色反射颜色,以提供具有大于-6的a *值的反射颜色, 至少65%的光反射,优选至少70%。 内反射增强层和反射层优选为硅,内反射增强层的光学厚度小于125nm; 可以是氧化硅的中间反射增强层优选具有大于125nm的光学厚度。 可以通过在玻璃制造过程中将连续的层沉积在热的玻璃带上来制造镜子。

    • A method of pyrolytically forming a silica-containing coating on a glass substrate at an elevated temperature. Silane, oxygen, a radical scavenger gas and a carrier gas are combined as a precursor mixture, and the precursor is directed toward and along the surface of the heated glass substrate. The presence of the radical scavenger allows the silane, which is pyrophoric, to be premixed with the oxygen without undergoing ignition and premature reaction at the operating temperatures. The radical scavenger further provides control of and permits optimization of the kinetics of the chemical vapor deposition (CVD) reaction on the glass. A preferred combination of precursor materials includes monosilane and oxygen, with ethylene as the radical scavenger, and including nitrogen as a carrier gas.
    • 在高温下在玻璃基板上热解形成含二氧化硅的涂层的方法。 将硅烷,氧气,自由基清除剂气体和载气合并作为前体混合物,并将前体指向并沿着加热的玻璃基底的表面。 自由基清除剂的存在允许自燃的硅烷与氧预混合,而不会在操作温度下发生点火和过早反应。 自由基清除剂进一步提供对玻璃上的化学气相沉积(CVD)反应的动力学的控制并允许其优化。 前体材料的优选组合包括甲硅烷和氧,乙烯作为自由基清除剂,并且包括作为载气的氮。

    • A device for the formation, by pyrolysis, of a coating on a face of a hot glass substrate includes a vault; support elements for conveying the substrate along a path through a coating chamber defined between the main vault and the substrate; elements for supplying and distributing gaseous reagent to the coating chamber; elements for discharging exhaust gas from the coating chamber; and a plurality of struts. The elements for supplying and distributing gaseous reagent to the coating chamber include an ejection nozzle having defined therein a slot which opens directly into the coating chamber, has opposing longitudinal internal walls, extends transverse to the path of the substrate, and has a length which is substantially equal to the coating width of the coating formed. The plurality of struts are positioned at spaced intervals and connect the opposing walls of the slot together to thereby maintain the walls of the slot in substantially parallel disposition. The ejection nozzle has longitudinal internal walls which define a continuous convergent path which terminates at and communicates with the slot and has an angle of convergence (.alpha.), thereby causing the flow of gaseous reagent to conform to the slot, the angle of convergence (.alpha.) of the convergent path being up to but not greater than 14.degree. at any point. Alternatively, instead of a plurality of struts, the device may include elements for trapping stray deposits including at least one metal bar disposed below the vault of the coating chamber.
