Overview of ODM OEM Zirconium Aluminum Nitride Square Metal Melting Boat Silicon Carbide Zirconia Alumina Ceramic Crucible

Aluminum Nitride Ceramic is an advanced ceramic material with aluminum nitride as the main component. It has been widely used in electronics, optics, and mechanics due to its unique properties.

Features of ODM OEM Zirconium Aluminum Nitride Square Metal Melting Boat Silicon Carbide Zirconia Alumina Ceramic Crucible

High thermal conductivity: Aluminum nitride ceramics have relatively high thermal conductivity, usually between 170-260 W/m·K, which makes it an excellent heat dissipation material. It is especially suitable for electronic devices that require efficient heat dissipation, such as substrate materials for power semiconductor devices.

Good electrical insulation: Despite its high thermal conductivity, aluminum nitride ceramics are excellent insulators of electricity, which can effectively prevent current leakage and ensure the safe operation of electronic components.

Low dielectric constant and dielectric loss: These characteristics make aluminum nitride ceramics very suitable for use in high-frequency circuits because it can reduce energy loss during signal transmission.

High temperature resistance: Aluminum nitride ceramics can maintain structural stability and strength at extremely high temperatures. Its melting point is about 2800°C, so it is suitable for applications in high temperature environments.

Low thermal expansion coefficient: Compared with semiconductor materials such as silicon, aluminum nitride has a lower thermal expansion coefficient, which means it has better dimensional stability when the temperature changes, which helps improve packaging reliability.

Corrosion resistance: Aluminum nitride ceramics have good chemical stability to most molten metals and are not easily oxidized or corroded, allowing them to perform well in harsh environments.

High mechanical strength: Although not as hard as some other types of ceramic materials, aluminum nitride ceramics still provide enough mechanical strength to allow them to be used in many structural applications.

Specifications of ODM OEM Zirconium Aluminum Nitride Square Metal Melting Boat Silicon Carbide Zirconia Alumina Ceramic Crucible

These crucibles melt metals. They handle high heat. They last long. They work for gold, silver, platinum, and other precious metals. Factories and labs use them often.

The material is strong. It mixes zirconia and alumina ceramics. This mix fights heat shock well. It does not crack easily when temperature changes fast. The crucible resists very high temperatures. It works safely up to 1700 degrees Celsius. It keeps its shape under heat stress.

It also fights chemicals. Acids and alkalis do not damage it much. This is important for pure melts. You get less contamination. The surface stays smooth over time. This stops metal from sticking inside. Cleaning is easier later.

The shape is square. This design fits many furnaces. It saves space on heating elements. Heat spreads evenly inside. Melting happens faster and more consistently. The corners are strong. They resist chipping during handling.

Different sizes are available. Common sizes are 10ml, 25ml, 50ml, 100ml, 250ml, and 500ml. You choose the size matching your metal amount. Larger sizes hold more material. Smaller sizes are good for tests.

Applications of ODM OEM Zirconium Aluminum Nitride Square Metal Melting Boat Silicon Carbide Zirconia Alumina Ceramic Crucible

These crucibles tackle tough melting jobs. Zirconium aluminum nitride (ZrAlN) is the key material. It handles extreme heat well. It doesn’t easily crack from sudden temperature changes. It resists chemical attack from molten metals. This makes ZrAlN crucibles reliable. They last longer under harsh conditions.

Square melting boats are popular. Their shape fits well inside furnace chambers. This saves space. It allows efficient batch processing. Workers can easily load and unload them. The square design maximizes usable surface area. More material fits inside for melting.

Silicon carbide (SiC) crucibles offer another option. They are very hard. They conduct heat efficiently. This speeds up melting cycles. They are good for processes needing fast heat transfer. SiC also resists abrasion well. But it can react with some very aggressive metals.

Zirconia alumina ceramics provide high strength. They combine toughness with good thermal properties. They resist thermal shock effectively. These crucibles suit applications needing structural integrity. They withstand physical stress during handling. They manage repeated heating and cooling cycles.

Choosing the right crucible matters. Consider the metal type, melting temperature, and atmosphere. ZrAlN excels with reactive alloys needing inert protection. SiC works well for rapid heating in less corrosive environments. Zirconia alumina offers robust performance for general high-temperature tasks. Manufacturers build these crucibles precisely. They use advanced sintering techniques. This ensures consistent quality and performance. Proper crucible selection prevents contamination. It improves process yield. It reduces costly downtime. These tools are vital for labs and industrial metal production. They handle precious metals, semiconductors, and specialty alloys reliably.

5 FAQs of ODM OEM Zirconium Aluminum Nitride Square Metal Melting Boat Silicon Carbide Zirconia Alumina Ceramic Crucible

What are these melting boats made of?
Our square melting boats use a special coating. This coating is zirconium aluminum nitride. It goes over a strong silicon carbide base. The combination handles extreme heat well. It also resists chemical reactions during melting processes.

How hot can these crucibles get?
These crucibles handle very high temperatures. They work safely up to 1650°C (3002°F) in air. Some models go even higher in controlled atmospheres. Check the specific product details for exact limits. Always follow the manufacturer’s guidelines.

Do they last longer than graphite boats?
Yes, generally they do. The zirconium aluminum nitride coating is very tough. It resists wear from molten metals much better than standard graphite. This means you replace them less often. It saves money over time despite a higher initial cost.

Can I clean and reuse them?
Often yes, but carefully. Let the boat cool completely first. Remove any leftover material gently. Avoid harsh tools that scratch the coating. Light brushing or compressed air usually works. Inspect for cracks or damage before reuse. Severely damaged boats need replacing.

What chemicals won’t react with them?
These crucibles resist many common chemicals. They handle molten metals like gold, silver, copper, and aluminum well. They also resist many fluxes and salts used in melting. Avoid strong alkalis like sodium hydroxide. Avoid hydrofluoric acid too. These can damage the coating. Check chemical compatibility charts for specifics.
