Molybdenum Crucible Overview:
Our cylindrical molybdenum crucible is a premium-grade pure molybdenum crucible designed for specialized industrial and research applications requiring extreme thermal stability, corrosion resistance, and durability. Tailored for small-scale operations, this compact molybdenum container excels in handling high-temperature processes, molten metals, and reactive materials, making it indispensable in fields such as semiconductor manufacturing, crystal growth, and advanced material synthesis.
Crafted from 99.95% pure molybdenum, our crucibles combine precision engineering with robust construction to deliver unmatched performance in demanding environments. Available in diameters ranging from 20 mm to 100 mm, these molybdenum crucible liners are ideal for laboratory setups, thin-film deposition systems, and compact industrial furnaces where space optimization and material integrity are critical.
Key Features & Advantages of high purity Mo crucible:
1. Ultra-High Temperature Resistance
With a melting point of 2,623°C (4,753°F), our pure molybdenum crucible withstands sustained operation at temperatures up to 2,000°C in inert or vacuum environments. This makes it suitable for processes like sapphire crystal growth, rare metal smelting, and high-purity alloy production.
2. Superior Corrosion Resistance
Molybdenum’s innate resistance to molten salts, acids, and alkaline solutions ensures the cylindrical molybdenum crucible remains unaffected by aggressive chemical reactions, extending its lifespan even in harsh operating conditions.
3. Optimized Thermal Conductivity
The material’s excellent thermal conductivity ensures uniform heat distribution, minimizing thermal stress and reducing the risk of cracking during rapid heating or cooling cycles.
4. Precision Manufacturing
Each molybdenum crucible liner undergoes CNC machining and surface polishing to achieve micron-level dimensional accuracy, ensuring seamless integration with vacuum chambers, CVD reactors, and other equipment.
5. Compact & Lightweight Design
Designed for small-batch processing, our crucibles maximize workspace efficiency without compromising capacity. Their cylindrical geometry enhances structural stability while facilitating easy material loading/unloading.
6. Customizable Options
Available in standard sizes or tailored dimensions, including wall thickness, depth, and flange configurations, to meet unique application requirements.

Handling & Maintenance Guidelines:
Pre-Use Conditioning: Preheat crucibles slowly under vacuum or inert gas to remove surface contaminants.
Avoid Oxidation: Limit exposure to oxygen above 400°C; use protective coatings or atmosphere control systems.
Cleaning: Use non-abrasive methods (e.g., ultrasonic cleaning with ethanol) to preserve surface integrity.
Storage: Keep in dry, low-humidity environments to prevent oxidation.
Quality Assurance:
Every cylindrical molybdenum crucible undergoes rigorous inspection, including:
Chemical Composition Analysis
Density Testing (Archimedes’ Method)
Dimensional Verification (CMM Measurement)
Surface Defect Inspection
FAQ
Q: Can this crucible be used for melting platinum or gold?
A: Yes. The molybdenum crucible liner is ideal for precious metal processing due to its non-reactive properties.
Q: What is the lead time for custom-sized orders?
A: Standard delivery is 2–3 weeks; custom designs require 4–5 weeks based on complexity.
Q: How does molybdenum compare to tungsten crucibles?
A: Molybdenum offers better machinability and cost-effectiveness for moderate-temperature applications, while tungsten excels in ultra-high-temperature (>2,200°C) scenarios.
Q: Is your product reusable?
A: Yes, with proper maintenance, our crucibles can endure hundreds of thermal cycles.

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.
