Transparent fused silica glass and use thereof

Abstract

The invention relates to the technical field of optical glass, in particular to transparent fused silica glass used for manufacturing halogen incandescent lamp glass bulb materials and capable of absorbing ultraviolet light and a part of yellow light, and use thereof. The transparent fused silica glass comprises the following ingredients in parts by weight: 95.00-110.00 parts of silicon dioxide, 0.50-1.20 parts of cerium oxide, 1.10-2.00 parts of alumina and 2.60-3.50 parts of neodymium oxide. The invention further provides a use of transparent fused silica glass. According to the invention, the doping proportion of the alumina and the neodymium oxide is adjusted, so the transparent fused silica glass can absorb a part of yellow light in the visible light so as to improve the photochromic, reinforce the luminous effect and improve the definition of halogen incandescent lamps; besides, potassium oxide or sodium oxide is added in the transparent fused silica glass of the invention to control the smelting temperature thereof to 1450-1600 DEG C, thereby reducing the technique difficulty of manufacturing halogen incandescent lamp glass bulbs and improving the plasticity of the halogen incandescent lamp glass bulbs.

Description

technical field [0001] The invention relates to the technical field of optical glass, in particular to a transparent quartz glass capable of absorbing ultraviolet light and part of yellow light used for manufacturing glass bulb materials of halogen incandescent lamps and its application. Background technique [0002] The Chinese patent application number is 9911446.5, and the patent application name is "transparent quartz glass capable of absorbing ultraviolet rays and its application". Although it can absorb ultraviolet rays, the efficiency of absorbing the yellow spectrum is relatively low. If it is used to heat a tungsten filament to emit light, it will cause more yellow spectrum in the emission spectrum, the color is yellowish, and the visual clarity is poor, which brings discomfort to people's vision; and the melting of quartz glass produced by the prior art The temperature is about 1680 to 1800 degrees. In this way, when manufacturing halogen incandescent lamps, due to...

[0002] The Chinese patent application number is 9911446.5, and the patent application name is "transparent quartz glass capable of absorbing ultraviolet rays and its application". Although it can absorb ultraviolet rays, the efficiency of absorbing yellow spectrum is low

If it is used to heat a tungsten filament to emit light, it will cause more yellow spectrum in the emission spectrum, the color is yellowish, and the visual clarity is poor, which brings discomfort to people's vision; and the melting of quartz glass produced by the prior art The temperature is about 1680 to 1800 degrees. In this way, when manufacturing halogen incandescent lamps, due to the high melting temperature, the process difficulty of manufacturing halogen incandescent lamps is increased, and the brittleness of the glass bulb of halogen incandescent lamps becomes larger, and the melting of the quartz glass tube Temperature is difficult to control, affecting the quality of halogen incandescent lamps
