Specifications of Refractory Zirconia Coated Saggar Zro2 Ceramic Crucible for Raw Material Calcination

These crucibles handle demanding calcination processes. They are called zirconia coated saggar crucibles. The key feature is their coating. It’s made from zirconium dioxide, known as ZrO2. This material is excellent for resisting extreme heat. The coating protects the crucible body underneath. This body is usually ceramic too. Together, they form a very strong container. It is designed for repeated use under tough conditions.

The ZrO2 coating provides important benefits. It significantly improves resistance to chemical attack. Many raw materials are highly reactive at high temperatures. The coating helps prevent contamination. It also reduces wear from thermal cycling. Crucibles heat up and cool down many times. This coating makes them last longer. It withstands temperatures over 1500°C easily. Some grades handle even higher heat. This makes them perfect for calcining sensitive materials.

These crucibles come in various sizes. Common shapes are cylindrical or box-like. They often have lids. The lids help contain the material inside. They also protect it from the furnace atmosphere. The base crucible material is carefully chosen. It must be compatible with the zirconia coating. It must also be strong enough. Typical base materials include alumina or other ceramics. The coating is applied as a dense layer. This layer bonds well to the base.

People use these crucibles for calcining many materials. Examples include lithium cobalt oxide for batteries. They are also used for rare earth elements. Ceramic powders and pigments are other common uses. The crucibles provide a stable, inert environment. This is crucial for producing consistent, high-purity products. Their durability saves money over time. They reduce the need for frequent replacements. They also minimize downtime for furnace loading.

Applications of Refractory Zirconia Coated Saggar Zro2 Ceramic Crucible for Raw Material Calcination

Refractory zirconia coated saggar crucibles tackle big problems in raw material calcination. You need high temperatures. But harsh conditions can damage regular crucibles. They might crack. They might react with your materials. Contamination ruins your product. These saggar crucibles feature a special zirconia coating. This coating is key. It forms a tough shield. This shield protects the crucible body underneath. The zirconia layer acts as a barrier. It stops your raw materials from sticking to the crucible walls. It prevents chemical reactions. This keeps your materials pure. You get better product quality. Uncoated crucibles wear out fast. They crack and degrade quickly. This means constant replacement. That costs money and time. The zirconia coating greatly extends the crucible’s lifespan. It protects the surface from direct attack. This resistance means the crucible lasts much longer. You save on replacement costs. You reduce downtime. Thermal shock is another challenge. Kilns heat up and cool down. Sudden temperature changes stress materials. Standard crucibles often break under this stress. Zirconia coated saggars handle it better. The coating improves thermal shock resistance. The crucible stays intact through rapid heating and cooling cycles. This reliability is crucial for consistent production. Material compatibility matters too. Different raw materials need calcining. Some are very reactive. Others are abrasive. The inert zirconia coating works with many materials. Think about rare earth elements. Think about battery cathode powders. Think about special ceramics. These crucibles protect your valuable materials. They provide a stable, non-reactive environment. This is vital for precise calcination results. You achieve the desired material properties. The coating ensures consistent performance batch after batch.

5 FAQs of Refractory Zirconia Coated Saggar Zro2 Ceramic Crucible for Raw Material Calcination

This crucible holds materials for high-temperature heating. It keeps things separate during calcination. The main part is alumina ceramic. The inside gets a special zirconia coating.

What is this crucible used for?
You use it to heat raw materials very hot. This process is called calcination. It helps prepare materials for further use. The crucible protects the contents from contamination.

Why is there a zirconia coating?
The zirconia layer makes the crucible better. It stops materials from sticking to the surface. This makes cleaning easier. It also protects the crucible itself from damage. This coating acts like a protective shell.

How long does this crucible last?
It lasts longer than uncoated ones. The zirconia coating fights wear and tear. It handles the extreme heat better. You get more uses from it. This saves money over time.

How hot can it get?
It handles very high temperatures. It works well above 1500°C. The exact limit depends on the specific material grade. Always check the manufacturer’s maximum temperature rating.

Does it resist chemicals?
Yes, it shows good chemical resistance. The zirconia coating helps. It protects against reactions with the materials inside. This keeps the calcination process stable.
