Example Embodiment

[0017] The present invention will be further described below in conjunction with the drawings and embodiments.

[0018] A production method of low-hydroxyl yellow doped quartz tube includes the following steps:

[0019] 1) Select high-purity quartz raw materials, where the content of Sio2 is ≥99.95%, and the particle size of quartz sand is 60-150 mesh;

[0020] 2) Put the reagent and the raw material into the agitator to mix and stir evenly; the reagent includes europium nitrate or europium oxide with a weight of 0.1-1% of the raw material, and aluminum nitrate or 0.1-1% of the weight of the raw material Alumina

[0021] 3) Carry out high-temperature continuous baking of the uniformly mixed raw materials at a baking temperature of 900°C to 1300°C, so that the quartz raw materials and the mixed reagents can completely remove water during the high-temperature baking process;

[0022] 4) Put the baked raw materials into the continuous melting furnace for melting, and then pull the tube dr...

Abstract

The invention relates to a production method of a low hydroxy yellow doped quartz tube. The production method includes the steps: 1) selecting high-purity quartz raw materials; 2) placing reagents and the raw materials into a stirrer and uniformly mixing and stirring the raw materials; 3) continuously baking the uniformly mixed raw materials at high temperature; 4) throwing the baked raw materials into a continuous melting furnace for melting, drawing the raw materials by a tube drawing machine to prepare an integrally colored yellow quartz tube; 5) placing the drawn yellow quartz tube into a vacuum or air dehydroxylation furnace for high-temperature dehydroxylation. The production method is reasonable in design, smooth in flow, and the drawn yellow quartz tube can be more uniform in color and better in size and transmittance consistency.

Description

technical field [0001] The invention relates to a production method of a quartz tube, in particular to a production method of a low hydroxyl and yellow quartz tube, specifically a production method of a low hydroxyl yellow doped quartz tube. Background technique [0002] Yellow quartz tube is a special doped quartz glass tube that can be used in equipment such as lasers. However, due to the limitation of factors such as equipment and technology, most of the currently produced yellow quartz tube products are unevenly colored, the product qualification rate is low, and the price is expensive. Therefore, it is necessary to design a production method that can improve product quality and reduce costs. . Contents of the invention [0003] The purpose of the present invention is to provide a production method for low-hydroxyl yellow doped quartz tubes in view of the problems currently encountered in the production of yellow quartz tubes. The consistency of rate performance is g...
