Abstract

The invention discloses a production method of a light yellow quartz glass tube. The production method comprises the following steps: (S1) taking a quartzite raw material containing over 99% of SiO2 and lower than 20ppm of impurities, and breaking the quartzite raw material to obtain a quartzite material of 50-70 meshes; and (S2) transferring the quartzite in the step (S1) into a flushing tank for primary cleaning, flushing off the sediment, and airing the flushed quartzite material; and adding sodium nitrate and potassium nitrate in a ratio of 1:2 into the quartzite material and stirring to obtain a quartzite mixed material. According to the invention, a solution A is prepared by adding hydrochloric acid into europium oxide, vanadium pentoxide, yttrium oxide, praseodymium oxide and lanthanum oxide in (S5); a solution B is prepared by adding water into sodium nitrate and ammonium metavanadate; and the solution A and solution B are mixed and roasted with the quartzite material, the quartzite material is fully colored, mixed color is avoided, and a quartz glass tube with high-purity color can be obtained.

Description

technical field [0001] The invention relates to the technical field, in particular to a production method of a light yellow quartz glass tube. Background technique [0002] Quartz glass tube is a special industrial technical glass made of silica. It is a very good basic material (silicon content 9999). Quartz glass has a series of excellent physical and chemical properties, such as: [0003] 1. High temperature resistance. The softening point temperature of quartz glass is about 1730°C, and it can be used for a long time at 1100°C, and the highest service temperature for a short time can reach 1450°C. 2. Corrosion resistance. In addition to hydrofluoric acid, quartz glass hardly reacts with other acids, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, especially its chemical stability at high temperatures, which cannot be achieved by any other engineering materials. In comparison, 3. Good thermal stability. The thermal expansion ...
