CTIA's Tungsten Heater in High Temperature Sintering
CTIA’s tungsten heater is a high-temperature resistive heater fabricated from high-purity tungsten wire or doped tungsten wire through precision stranding, coiling, forming, and vacuum high-temperature setting processes. The tungsten heating component is used in vacuum furnaces and controlled atmosphere furnaces to provide a stable thermal field for the densification of metal powders, ceramic materials, and refractory alloys. It finds extensive use in cemented carbide sintering, advanced ceramic processing, nuclear material components, and high-performance magnetic material heat treatment.
High temperature sintering requires high temperature capability, uniform thermal distribution, and long-term operational stability. CTIA’s tungsten heater offers the following advantages:
(1) High temperature resistance: With a melting point of about 3410°C, it maintains structural stability even above 2000°C, supporting continuous sintering operation.
(2) Low contamination: Low vapor pressure under high vacuum or protective atmospheres minimizes metal contamination and helps maintain material purity.
(3) Uniform thermal radiation: Stable electrical resistivity enables consistent heat distribution, reducing temperature gradients and improving densification uniformity.
(4) Long-term stability: Optimized grain structure and vacuum setting processes enhance creep resistance, resulting in minimal deformation during thermal cycling and extended service life.
Specifications of CTIA’s tungsten heater:
(1) Material: High-purity tungsten wire (≥99.95%) or doped tungsten wire
(2) Wire diameter (mm): 0.8–2.0
(3) Structure: Multi-strand precision twisted
(4) Heating structure: Spiral, hairpin, cage-type, and customized geometries
(5) Surface treatment: Electrolytic polishing or alkaline cleaning
