CTIA's Tungsten Heater in High Purity Material Evaporation
CTIA’s tungsten heater is a high-purity thermal source used in ultra-high vacuum evaporation equipment to heat high purity material such as metals or semiconductor materials, enabling low-contamination and high-cleanliness thin film deposition. The tungsten heater is fabricated from high-purity tungsten wire through precision stranding, coiling, forming, and multi-stage surface chemical purification processes.
High purity material evaporation requires exceptional cleanliness and thermal stability. Outgassing behavior and material purity of the heating component directly affect film quality. CTIA’s tungsten heater uses tungsten wire with a purity of ≥99.95% as the base material to minimize impurity introduction at the source. Degassing and surface purification treatments further reduce outgassing and contamination in vacuum environments. A high melting point of about 3410°C ensures structural stability under high temperatures, maintaining a uniform thermal field. Surface condition optimization also improves wettability and adhesion of molten materials, enabling more stable evaporation and better deposition consistency.
Tungsten heater is widely used in quantum device fabrication, superconducting thin film research, advanced semiconductor processing, and high-end optoelectronic material production, providing a stable heat source for high-purity thin film deposition and precision functional layer formation.
