Specifications of ZrO2 Crucible /Zirconia Ceramic Boat Crucibles with Lid

ZrO2 crucibles are ceramic containers made from zirconium dioxide. They come with matching lids. This material is very tough. It handles extreme heat well. Acids don’t touch it. Bases don’t hurt it either. This makes it perfect for demanding lab work and industrial processes.

The boat shape is common. It allows easy loading of samples. Powder goes in simply. Small parts fit well too. The lid is essential. It keeps things inside. It prevents contamination. It also helps control the atmosphere inside the crucible during heating.

These crucibles resist thermal shock brilliantly. Sudden temperature changes are okay. They won’t crack easily. This is a big advantage over other ceramics. You can heat them fast. You can cool them fast too. It saves time. It reduces breakage risk.

Zirconia stays strong at very high temperatures. These crucibles work reliably up to 1500°C. Some grades handle even higher heat. They don’t melt. They don’t slump. They keep their shape under load. This stability is crucial for consistent results.

Chemical inertness is another key feature. Most molten metals won’t react with ZrO2. Many aggressive chemicals are safe to use. This purity matters for sensitive experiments. It prevents sample contamination. You get accurate analysis.

Common sizes range from small capacities for tiny samples to larger ones for bulk material. The lid fits snugly. It forms a good seal. This is important for controlled environments. High purity is standard. 99% ZrO2 or better is typical. The material is often stabilized with yttria. This enhances its toughness and thermal properties. These crucibles last a long time. They hold up well over many uses. They are a solid investment for high-temperature applications.

Applications of ZrO2 Crucible /Zirconia Ceramic Boat Crucibles with Lid

Zirconia ceramic crucibles with lids, made from zirconium dioxide (ZrO2), are special containers for high-temperature work. They handle extreme heat incredibly well. This makes them perfect for demanding lab and industrial jobs. One major use is growing single crystals. Researchers need stable, non-reactive containers for crystal growth processes. ZrO2 crucibles provide that. They also work well in melting and purifying precious metals like platinum or gold. The crucible doesn’t react with the molten metal, keeping it pure. These crucibles are essential in thermal analysis too. Instruments like TGA (Thermogravimetric Analysis) require inert sample holders for accurate weight measurements at high temperatures. ZrO2 crucibles deliver reliable performance here. The semiconductor industry relies on them heavily. They are used in processes like diffusion and oxidation of silicon wafers. The crucibles withstand the harsh furnace conditions without contaminating the sensitive materials. The tight-fitting lid is crucial. It minimizes material loss from evaporation or splashing. It also helps control the atmosphere inside the crucible during sensitive reactions. Their resistance to chemical attack is another key benefit. They don’t corrode easily when exposed to aggressive chemicals or molten materials. This durability translates to a longer service life compared to other ceramic options. This saves money over time. Handling is straightforward. They are designed for stability and ease of use within high-temperature furnaces.

5 FAQs of ZrO2 Crucible /Zirconia Ceramic Boat Crucibles with Lid

What’s the highest temperature this crucible can handle?
These crucibles handle temperatures up to 1800°C. They are stable there. They resist thermal shock well. Sudden temperature changes won’t crack them easily. This makes them good for demanding heating cycles.

Will chemicals damage the zirconia crucible?
Zirconia resists most acids and alkalis very well. It handles strong chemicals better than many other ceramics. It won’t corrode easily. This is important for melting aggressive materials. Check specific chemical compatibility for your exact use.

Why pick zirconia over alumina?
Zirconia is tougher. It resists cracking better under stress. It handles thermal shock better than alumina. It’s also more inert chemically. This suits it for harsh environments. Alumina is cheaper but less durable in extreme conditions.

Do I really need the lid?
Yes, the lid is important. It keeps your sample contained. It prevents contamination from the furnace atmosphere. It helps maintain a stable environment inside. It minimizes material loss through evaporation. The lid ensures better results.

How do I clean it after use?
Cleaning is usually simple. Let the crucible cool down completely first. Use warm water and mild detergent. A soft brush helps remove residue. For stubborn material, dilute acids might work. Avoid abrasive cleaners. Check manufacturer advice for difficult residues.
