Pure Tungsten Heater
1.What Is Pure Tungsten Heater?
Pure tungsten heater, also known as tungsten wire heater, is a vacuum evaporation element fabricated from high-purity tungsten wire with a purity of not less than 99.95%. It is processed in single-strand or multi-strand twisted forms, then further shaped into funnel-shaped, hump-shaped (single-peak or double-peak), U-frame, or other customized configurations.
2.How Does Pure Tungsten Heater Work?
Under high-vacuum conditions, electric current passes through the heater and generates heat through the electrical resistance of tungsten, enabling the heating and evaporation of source materials or workpieces.
3.What Are the Features of Pure Tungsten Heater?
(1) High purity: High-purity tungsten helps reduce impurity release during high-temperature operation, minimizing contamination risks and improving film purity and stability.
(2) Stable thermal performance: Low vapor pressure at elevated temperatures enables stable heat output and precise evaporation rate control for consistent processing.
(3) Flexible geometric forming: Tungsten wire can be formed into hump-shaped, funnel-shaped, coil-shaped, straight-shaped, U-frame, hook-shaped, and other configurations to match various equipment and installation requirements.
4.What Are the Applications of Pure Tungsten Heater?
(1) Precision optical coating: Used to heat and vaporize metals or fluorides in vacuum chambers for anti-reflection or high-reflection coatings on lenses, prisms, and mirrors.
(2) Semiconductor leads and electrodes: Used for metallization deposition in power devices and integrated circuits. A stable thermal field helps ensure dense conductive layers.
(3) Vacuum electronic devices: Used as cathode heating components or electron source heating elements in cathode ray tubes, emission tubes, and related devices.
(4) Laboratory research: Used as a heating source for micro-quantity material deposition in research laboratories.
