Problems solved by technology

At present, ordinary corundum ceramics are mostly used as the insulation layer in high-temperature crystal growth furnaces. The material is loose, the surface is rough, and solid particles are easy to adhere to, and it is not easy to clean, which will eventually affect the purity of the crystal and is very unfavorable to crystal growth.

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] Such as figure 1 As shown, it is the inner wall structure of the heat preservation cover of a crystal growth furnace of the present invention. A dense ceramic thin layer 2 is sprayed on the surface of the heat preservation cover inner wall 1. The dense ceramic thin layer 2 is made of the same material as the heat preservation cover inner wall 1. . In order to prevent the sputtered ceramic thin layer 2 from being cracked due to uneven heating, the inner wall 1 of the heat preservation cover of the present invention is arranged in a grid shape, so that the ceramic thin layer 2 can be cracked naturally, so that the cracking is within a controlled range, avoiding In order to produce debris due to uneven heating and shattering. The ceramic thin layer 2 is made of the same material as the inner wall 1 of the heat preservation cover, preferab...

Abstract

The invention relates to the field of crystal growth, and discloses a heat-insulating cover structure for a crystal growth furnace. The heat-insulating cover structure for a crystal growth furnace comprises a heat-insulating cover inner wall, wherein the heat-insulating cover inner wall is of a latticed structure, and a compact ceramic thin layer is sprayed on the surface of the heat-insulating cover inner wall. According to the heat-insulating cover structure for a crystal growth furnace disclosed by the invention, a compact ceramic thin layer made from the same material as the heat-insulating cover inner wall is sprayed on the surface of the heat-insulating cover inner wall by adopting a high-temperature plasma spraying method, and the ceramic thin layer is mechanically polished; and the compact ceramic thin layer is sprayed on the heat-insulating cover inner wall, so that the surface of the inner wall is compact and smooth, not easy to attach foreign matters, and easy to clean, thus finally reducing influence on crystal purity.

Description

technical field [0001] The invention relates to the field of crystal growth, in particular to a heat preservation cover structure of a crystal growth furnace and a manufacturing method thereof. Background technique [0002] Crystal is the core component of solid-state lasers, and its optical uniformity determines the quality of solid-state lasers. At present, ordinary corundum ceramics are mostly used as the insulation layer in high-temperature crystal growth furnaces. The material is loose, the surface is rough, and solid particles are easy to adhere to, and it is not easy to clean. This will eventually affect the purity of the crystal and is very unfavorable to crystal growth. Contents of the invention [0003] In order to overcome the above-mentioned problems, the present invention proposes a heat preservation cover structure of a crystal growth furnace and a manufacturing method thereof. A dense ceramic thin layer is sprayed on the inner wall of the heat preservation c...
