Abstract

The invention discloses a device for producing high-quality synthetic quartz glass, which comprises a furnace body with a closed reaction chamber inside; the reaction chamber has an exhaust channel; a burner is arranged on the upper part of the reaction chamber to generate a heating zone, and the heating zone The silicon-containing raw material in the furnace is heated to form a loose body; the heater is set in the reaction chamber and is located below the burner to generate a sintering zone, and the loose body is sintered into a glass body in the sintering zone; the support column is located in the reaction chamber at one end and extends Into the heating zone and sintering zone, its outer wall forms a seal with the outer wall of the furnace body; as the quartz glass is synthesized, the support column can rotate along its own length and take its own axial center as the rotation axis, and move away from the burner . The equipment has simple process, easy operation and low labor cost. The whole production process from raw material input to vitrification can be completed in the same equipment. The finished product has higher ultraviolet transmittance, which is conducive to the preparation of ultra-high purity products.

Description

technical field [0001] The invention relates to the technical field of quartz glass preparation, in particular to a device for producing high-quality synthetic quartz glass. Background technique [0002] High-quality synthetic quartz glass can be made into a variety of high value-added products (or semi-finished products), which are widely used in the national defense and civilian markets. In the field of national defense and military industry, it is used as high-power laser lens, window material, etc.; in the aerospace industry, it is used to manufacture fairings and window materials for space telescopes, satellites and spacecraft. In the civilian market, it is mainly used in the electronic information and semiconductor industries, and is used as an important photomask substrate and quartz wafer in the production process of IC chips and flat panel displays; in the field of optical fiber communication, it is used to manufacture optical fiber preforms and optical fibers; in p...
