Abstract
The invention provides a high-refractivity, light-reflecting microspheric glass, comprising the following components in gram molecular percent: SiO2 1-12, B2O3 1.5-11, TiO2 20-55, BaO2 5-56, CaO 2-10, ZnO 0.3-10 and Sb2O3 0.1-2. And it has characters of high reflection brightness, no harmful components, and safety and no pollution.
Description
Technical field: [0001] The present invention relates to reflective beaded glass, especially high refractive index reflective beaded glass. Background technique: [0002] A lot of work has been done on the microbead glass material by predecessors. "Glass and Enamel" in 1988, 16(6)-36 "Glass Microbeads and Application Research" introduced that the main composition of glass is SiO 2 B 2 o 3 、Al 2 O, BaO, TiO 2 , The refractive index is 1.87~2.04 or 2.10~2.21, respectively, the magazine 2001, 29 (5)-44-47 article from the aspects of the influence factors of the performance parameters of the glass beads, the selection of the chemical composition system and so on. Changchun Institute of Optics and Fine Mechanics Journal 1996, 19(4)-4-49 "Research and Production of High Refractive Index Glass Beads" describes the powder method of forming beads. China Science and Technology Achievement Library 194201782 "Research and Production of High Refractive Index Glass Beads" describes ...
