Embodiment Construction

[0018] A laser quartz rod with a diameter of more than 320mm, using high-purity quartz sand as the basic raw material by weight, and adding 2.1% to 3.8% by weight of trace element additives,

[0019] The optimal weight portion of trace element additives is 2.9%~3.3% of the quartz sand,

[0020] Using SiO 2 The content is greater than 99.998%, the impurity content is less than 3ppm, and the high-purity quartz sand is 40~150 mesh. SiO 2 The content is a mass percentage, and the impurity content also refers to a mass ratio. When ppm represents the content in solids, it refers specifically to the mass ratio or weight ratio.

[0021] Wherein the trace element additive is made up of the following raw materials of weight ratio:

[0022] Yttrium oxide Y 2 o 3 0.3~0.5 Erbium oxide Er 2 o 3 0.1~0.3

[0023] Neodymium oxide Nd 2 o 3 0.4~0.6 potassium carbonate K 2 CO 3 0.2~0.4

[0024] α-alumina α-Al 2 o 3 0.1~0.3.

[0025] The preparation method of the a...

Abstract

The invention discloses a large-caliber laser quartz rod with the caliber of more than 320mm. The large-caliber laser quartz rod is prepared from basic weight parts of raw material of high-purity quartz sand and 2.9 to 3.3 weight parts of microelement additive, wherein the microelement additive consists of the following components in part by weight: 0.3 to 0.5 part of um oxide, 0.1 to 0.3 part oferbium oxide, 0.4 to 0.6 part of neodymium oxide, 0.2 to 0.4 part of potassium carbonate, and 0.1 to 0.3 part of alpha-alumina. The large-caliber laser quartz rod drawn by a whole rod doping preparation process has the caliber of 320mm, is not required to be coated with a film, has good optical uniformity, high transparency, no core, no scattering and no malposition, has the transmittance of 99.8percent, the finish of more than or equal to 60-40, the laser wavelength of 1.06mu m and the doping concentration error of + / -0.05 percent.

Description

technical field [0001] The invention relates to a preparation technology of quartz glass, in particular to a large diameter laser quartz rod with a diameter of more than 320mm. The invention also relates to a preparation method of the quartz rod. Background technique [0002] Laser quartz glass has the characteristics of specific optical properties and high optical stability. It has a large market demand and is suitable for industrial, civil, aviation and other fields. At present, there are only 2mm~12mm coated laser quartz rods on the market. Due to the limitation of small caliber, coating wear directly affects the use effect to a large extent. Contents of the invention [0003] The technical problem to be solved in the present invention is to address the deficiencies of the prior art, and propose a large-caliber laser quartz rod with a diameter of more than 320mm that does not require coating, has excellent optical uniformity, high transparency, no core, no scattering,...
