Embodiment Construction

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

[0018] A kind of production method of low hydroxyl yellow doped quartz tube, comprises the following steps:

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

[0020] 2) Put the reagent and the raw material into the shaker 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 europium oxide with a weight of 0.1-1% of the raw material alumina;

[0021] 3) The uniformly mixed raw materials are subjected to high-temperature continuous baking, and the baking temperature is 900°C to 1300°C, so that the quartz raw materials and the reagents mixed in can completely remove moisture during the high-temperature baking process;

[0022] 4) The baked raw materials are put into th...

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...
