Costs Graphite and Refractory Steel Crucibles for High-Performance Vacuum Finish

Material Composition and Pureness

Our crucibles are made from 99.95% pure graphite , molybdenum, or tungsten. Each product is picked for its capacity to take care of extreme warmth and harsh vacuum problems. The high purity level makes sure minimal contamination throughout the evaporation procedure. This makes the crucibles suitable for applications that require clean, regular outcomes.

Trick Features

These crucibles supply excellent thermal security and withstand contortion even at temperatures over 2000 ° C. Graphite variations give good electric conductivity and consistent heating. Molybdenum crucibles deliver strong mechanical toughness and reduced vapor pressure. Tungsten versions supply the highest possible melting point of all metals, making them ideal for refining reactive or high-melting-point materials.

Design and Compatibility

Each crucible is precision-machined to fit standard electron beam of light or thermal evaporation systems. The smooth inner surface reduces material sticking and supports reliable product usage. Requirement dimensions are readily available, and personalized measurements can be created upon demand. All crucibles go through strict high quality checks to guarantee consistent wall density and architectural honesty.

Applications

These crucibles are widely utilized in optical finish , semiconductor production, and thin-film study. They function well with metals like light weight aluminum, gold, silver, and different oxides. Their efficiency continues to be secure through duplicated home heating cycles, which aids extend life span and minimize downtime.

Handling and Treatment

Constantly deal with crucibles with clean, dry tools to avoid surface area damages or contamination. Store them in a dry atmosphere far from moisture and dirt. Stay clear of unexpected temperature level adjustments during procedure to stop cracking, specifically with graphite models. Appropriate use makes certain lasting dependability and optimum finishing quality.

Applications of 99.95% Graphite Crucible Molybdenum Material Tungsten Crucible For Vacuum Coating

High-Purity Crucibles for Demanding Vacuum Covering Processes

Developed for Extreme Conditions

Our 99.95% pure graphite crucibles and molybdenum or tungsten crucibles are made for laborious in vacuum finishing. These materials take care of really high temperatures without damaging down.

5 FAQs of 99.95% Graphite Crucible Molybdenum Material Tungsten Crucible For Vacuum Coating

Frequently Asked Questions

What is this crucible made of?

This crucible is made from high-purity graphite (99.95%) with molybdenum or tungsten components. These materials handle very high temperatures and stay stable in vacuum environments. They are common in thin-film coating processes.

Why choose a graphite crucible with molybdenum or tungsten?

Graphite gives good thermal conductivity and resists thermal shock. Molybdenum and tungsten add strength and prevent deformation at extreme heat. Together, they offer long service life and consistent performance during vacuum evaporation.

Can it be used in high-vacuum systems?

Yes. The crucible works well in high-vacuum and ultra-high-vacuum systems. Its materials release very little gas under vacuum, which helps keep the coating clean and pure.

What applications is it suitable for?

It is mainly used in physical vapor deposition (PVD) and electron-beam evaporation. Common industries include optics, semiconductors, solar cells, and display manufacturing. It holds and evaporates metals like aluminum, gold, or silver without reacting with them.

How do I extend its lifespan?

Avoid sudden temperature changes. Heat and cool the crucible slowly. Keep it clean and free from contaminants. Do not exceed the recommended operating temperature for your specific material—graphite handles up to 2,000°C in inert atmospheres, while molybdenum and tungsten go even higher in vacuum. Proper handling prevents cracks and extends use time.
