Cylindrical Pure Molybdenum Crucible Liners Container
We supply solid cylindrical molybdenum crucibles made of high-purity molybdenum raw material. These vessels fit daily industrial work and lab research, perfectly working under harsh conditions that need steady heat resistance and anti-corrosion ability.
This compact molybdenum container works great for high temperature treatment, molten metal handling and chemical reactive materials. It gets widely adopted in crystal growing, semiconductor production and new material development fields.
We adopt 99.95% pure molybdenum to produce all crucible products. With solid structure and fine processing, the items stay stable even under tough working surroundings. Our regular diameter ranges from 20mm to 100mm. Such size suits small lab equipment, thin film deposition devices and mini industrial furnaces, keeping complete material quality while saving operating space.
There are lots of advantages of our High Purity Molybdenum Crucible.
Strong heat resistant performanceMolybdenum material melts at 2623°C, and the crucible can keep stable running at 2000°C inside vacuum or inert gas space. Users can apply it to grow sapphire crystal, smelt rare metals and produce high purity alloy materials safely.
Good anti-corrosion capacityThe material itself hardly reacts with molten salt, acid and alkaline liquid. It will not be damaged by fierce chemical reaction, so the service lifespan can be effectively prolonged in bad working scenes.
Even heat conduction effectHeat spreads evenly inside the crucible thanks to fine thermal conductivity. It lowers inner thermal pressure and effectively stops cracking problems during frequent heating and cooling operations.
Accurate handmade & mechanical processingEach finished liner is processed by CNC cutting and surface polishing work. The size error stays within micron level, which makes easy matching with vacuum cavity, CVD reaction equipment and other common devices.
Portable cylindrical structureDesigned for small batch production, the crucible takes little room without reducing practical holding capacity. Round shape strengthens overall stability, also making material loading and taking out much simpler.
Flexible size customizationBesides regular standard sizes, we can adjust wall thickness, depth and flange style according to actual using demands to match different working requirements.
Our small molybdenum crucible is widely applied in many different industries:
Semiconductor & electronic field: Used for SiC and GaN crystal growth, also applied in sputtering target manufacturing
New material processing: Fit for melting titanium, zirconium and other rare metals, as well as high temperature ceramic sintering work
Optical and photovoltaic industry: Basic part for sapphire substrate and solar silicon making
Lab research: Support metallurgy test, nanomaterial study and aerospace material performance detection
Vacuum coating work: Act as material holding container for evaporation parts in PVD coating machines

High purity raw material cuts down impurity mixing during production, which is essential for making high-standard finished goods. The finished product can resist shape change, oxidation and thermal fatigue, and still works well after repeated high temperature cycles.
It can work normally under vacuum, hydrogen and argon atmosphere environments. Long service life helps clients cut down frequent replacement cost and reduce production halt time.
Daily Use & Maintenance Tips
Start slow preheating under vacuum or inert gas environment before formal use, to clear away dirt on the surface. Do not expose the crucible to oxygen environment when temperature exceeds 400°C, protective coating or sealed atmosphere can better protect the product.
Clean the surface with ethanol ultrasonic cleaning method only, avoid hard rubbing tools to prevent surface damage. Keep stored products in dry place with low humidity to avoid oxidation damage.
All finished crucibles will go through strict manual and machine inspection before delivery. Main checking items include chemical composition test, density detection with Archimedes principle, full size measurement and outer surface flaw inspection.
Frequently Asked Questions
Q: Can this crucible hold melted gold and platinum?
A: Sure it can. Molybdenum hardly reacts with precious metal, so it is a good choice for precious metal melting jobs.
Q: How long will we get customized goods?
A: Standard products can be delivered in 2 to 3 weeks. Custom-made items need around 4-5 weeks, subject to design difficulty.
Q: What is the difference between molybdenum and tungsten crucible?
A: Molybdenum is easier to process and more cost-friendly for medium temperature work. Tungsten suits working temperature above 2200°C extreme high temperature conditions.
Q: Can the crucible be reused many times?
A: Yes. Proper daily maintenance allows hundreds of times of repeated heating use.

Thank you!
At first we will make sure that we got all customer's requirements clear. Then place order to production department and inspection department. Each production process will test themselves if everything is right. And before shipping, all products will pass the packing department only after inspection department inspected that the products meet customer's requirements. If not, the products will go back to production department for fixing or remaking.
For production, normally our lead time is 20-30 days. But according to different products and different quantity, it changes a little. If your order is emergency, contact with us, we will find a way out to solve your problem. For shipping, normally we ship by express and air. Express takes about 7-10 days, and air 3-5 days. And if customer requires by sea, we will ship by sea, it takes normally 40-50 days.
All our products are shipped after strict inspection and safety packing. Inspection by each production process makes sure the quality is good. And the inspection department will inspect again carefully to make sure everything is right. But if quality issue really occurs, we are sorry, and we will be responsible. To fix the products or remake them, we will make everything right.
In order to keep our healthy cooperation, our payment term normally is 50% payment in advance, balance paid before shipping. And if customer needs, we will calculate the shipping cost for your reference.
