What Are Types of Tungsten Crucible?
CTIA's tungsten crucible is a refractory metal container based on high-purity tungsten, widely used in ultra-high temperature vacuum environments and high-purity material preparation. The types of tungsten crucible are systematically classified by manufacturing process, structural configuration, and application.
1. CTIA's Tungsten Crucible: Classification by Manufacturing Process
(1) Sintered Tungsten Crucible: Fabricated via powder metallurgy and high-temperature densification; offers a stable structure and high purity for wide high-temperature use.
(2) Forged Tungsten Crucible: Produced through high-temperature plastic deformation; features high density and superior creep resistance for long-term, high-load environments.
(3) Spun Tungsten Crucible: Formed using spinning technology; provides uniform wall thickness and high dimensional precision for advanced vacuum thermal fields.
(4) Stamped Tungsten Crucible: Stamped from tungsten sheets; delivers a cost-effective solution for mass-produced, small-to-medium specifications.
(5) Welded Tungsten Crucible: Formed by welding tungsten plates; provides structural flexibility for complex or customized geometries.
(6) Machined Tungsten Crucible: Precision-turned from forged tungsten rods; ensures high surface quality and tight tolerances for specialized small-scale applications.
2. CTIA's Tungsten Crucible: Classification by Structural Configuration
(1) Cylindrical Tungsten Crucible: Also known as round tungsten crucible; its standard geometry ensures structural stability and uniform heating, making it the most versatile shape for vacuum evaporation and melting.
(2) Tapered Tungsten Crucible: Engineered with a taper angle to optimize melt flow and thermal distribution, facilitating easier demolding and crystal extraction in growth systems.
(3) Boat-shaped Tungsten Crucible: Referred to as a tungsten boat; featuring an open design for easy loading and precise evaporation control in electron beam or thermal processes.
(4) Custom-shaped Tungsten Crucible: Custom-engineered based on specific equipment and process requirements for specialized thermal fields and research applications.
3. CTIA's Tungsten Crucible: Classification by Application
CTIA's tungsten crucible is utilized in ultra-high temperature sectors such as sapphire growth, semiconductors, vacuum coating, refractory metal melting, and nuclear material experimentation. Its performance characteristics, including ultra-high temperature stability, minimal vapor pressure, and high purity, ensure stable operation in extreme thermal environments.
The application classification of CTIA's tungsten crucible is shown as the picture bellow:
