Products Description
Graphite Heaters are high-efficiency heating elements for high-temperature vacuum furnaces, inert atmosphere furnaces, and continuous industrial furnaces, and are widely used in powder metallurgy, semiconductor, heat treatment, and new materials industries.
Products Advantages
High-Temperature Stability: Made with ≥99.9% high-purity graphite, it maintains structural stability at high temperatures, without softening or deformation.
High Thermal Efficiency: Graphite has a high thermal conductivity (100–150 W/m·K), resulting in fast thermal response and low heat loss.
Strong Chemical Stability: It does not react with most materials in a vacuum or protective atmosphere and does not release metallic impurities.
Compatible with Various Furnace Types: Can be processed into various structures such as rods, U-shapes, rings, and plates.
Products Applications
Powder Metallurgy Industry: Used in powder sintering furnaces and hot press furnaces to achieve high-temperature uniform heating.
Semiconductor and Electronic Materials: Suitable for crystal growth furnaces, diffusion furnaces, and annealing furnaces.
New Materials and Carbon Materials Industry: Used in high-temperature treatment and sintering processes of carbon/carbon composite materials and ceramic matrix composite materials.
Metal Heat Treatment Industry: Applied to equipment such as vacuum quenching furnaces, tempering furnaces, and high-temperature annealing furnaces.
Product Customization
Size Customization: Length, diameter, and cross-sectional shape can be manufactured according to drawings.
Resistance Value Customization: Resistance value designed based on power supply and heating curve.
Structure Customization: Straight rod type, bent type, spiral type, and irregular shape structures.
Surface Treatment: Polishing and coating treatment (for oxidation resistance).
Mounting Interface Customization: End connection methods and fixing structures to match different furnace bodies.
