Application Areas:

High-Temperature Furnaces: Used as furnace lining or insulation material in laboratory and industrial resistance furnaces, experimental furnaces, heat treatment furnaces, etc.

Chemical Analysis: Utilized as carbon determination and sulfur determination tubes in chemical analysis of steel.

Semiconductor Industry: Applied in high-temperature furnace tubes, such as those used for silicon single crystal growth.

Photovoltaic Industry: Employed in the production of solar panels, used as high-temperature furnace tubes.

Scientific Research: Serves as reactors or protective tubes in various high-temperature experiments and material synthesis.

Usage Precautions:

Temperature Control: It is recommended to maintain a heating and cooling rate of 5°C/Min to avoid thermal shock that could lead to furnace tube cracking.

Cleaning and Maintenance: Keep the interior of the furnace tube clean to prevent residues from reacting with Al2O3, which may cause cracking.

Insulation Measures: Place insulation plugs inside the furnace tube to create a balanced thermal field.

Support Frame Use: Use support frames to hold the flanges at both ends of the furnace tube to prevent deformation and breakage due to gravity.
