Abstract

The invention provides a yellow light filtering quartz rod and a preparation method thereof. According to the yellow light filtering quartz rod, high-purity quartz sand is used as a basic raw material in parts by weight, and a microelement additive which accounts for 0.1 percent to 5 percent of the weight of the high-purity quartz sand is matched; the microelement additive is prepared from vanadium pentaoxide V2O5, potassium nitrate KNO3, europium oxide Eu2O3, praseodymium oxide Pr6O11, titanium dioxide TiO2 and zinc hydroxide Zn(OH)2. The yellow light filtering quartz rod, which is drawn and molded by adopting a preparation process for coloring a whole rod body, has good coloring uniformity, high temperature resistance, acid and alkali resistance, small linear expansion coefficient, stable light filtering performance and a large light absorption range; the cut-off wavelength of absorption can reach 254nm to 360nm; the cut-off wavelength of the content of doped microelements can be adjusted to reach 400nm.

Description

technical field [0001] The invention relates to a preparation technology of a quartz rod, in particular to a yellow filter quartz rod and a preparation method thereof. Background technique [0002] The thermal expansion coefficient of quartz glass is lower than that of existing materials. It has the characteristics of high temperature resistance, very low thermal conductivity, excellent thermal shock resistance, high deformation temperature, softening temperature, low thermal conductivity and Dielectric loss, with extremely wide spectrum and optical transmission ability. Through the doped quartz glass, the proper proportion can even achieve the characteristics of zero expansion, so it is more and more widely used in chemical industry, semiconductor, electronics, optical fiber, aviation, electric light source, optical instrument, medical equipment, handicraft and other fields . At present, various manufacturers in the market only produce white quartz rods, which cannot meet...
