Problems solved by technology

[0002] When the usual quartz tube is used as a high-power light source tube, it has low impact resistance and is not resistant to radiation. After being excited by a strong light source for many times, the tube surface will turn white, and there will be crystallization on the tube surface, which seriously affects the transmission of high-energy light. Ordinary light The transmittance is 83%-87%, but the transmittance will drop to 75%-82% after being excited by a high-power light source for many times, resulting in the basic scrapping of high-power light source equipment

Abstract

A radiation-resistant high-transmittance quartz tube raw material for a super-high-power light source. The raw material includes the following components in the weight ratio: 0.01-0.03 parts of barium nitrate, 0.2-0.3 parts of cerium, 3-5 parts of high-purity water, and high-purity quartz sand 100-120 parts; when preparing, first weigh the components in proportion, then dissolve barium nitrate and cerium in high-purity water, and place them in a stirring furnace for stirring; then, add high-purity quartz sand and continue stirring to make the raw materials Stir well to make it dissolve and mix evenly, then send it to a sand oven for drying, and finally cool it to room temperature. This application adopts a special raw material doping process, using barium nitrate and cerium doping, which can effectively improve the transmittance of the quartz tube, and strengthen the impact resistance and radiation resistance of the quartz tube.

Description

technical field [0001] The invention relates to the technical field of quartz tube production, in particular to a radiation-resistant high-transmittance quartz tube raw material for a super-high-power light source, and specifically to a preparation method for the above-mentioned radiation-resistant high-transmittance quartz tube material for a super-high-power light source. Background technique [0002] When the usual quartz tube is used as a high-power light source tube, it has low impact resistance and is not resistant to radiation. After being excited by a strong light source for many times, the tube surface will turn white, and there will be crystallization on the tube surface, which seriously affects the transmission of high-energy light. Ordinary light The transmittance is 83%-87%, but the transmittance will drop to 75%-82% after being excited by a high-power light source for many times, resulting in the basic scrapping of high-power light source equipment.
