Specifications of High Purity Rectangular 95% 99% Al2o3 Alumina Oxide Ceramic Crucible Boats for Lab Melting

These alumina ceramic boats deal with high warmth in laboratories. They come rectangular for melting examples. You obtain two pureness selections: 95% or 99% Al2O3. Higher purity suggests much better performance usually. The 99% quality stands up to chemicals better. It deals with a lot higher temperatures as well. Both types endure abrupt temperature level modifications well. This is vital for melting and shooting processes.

These crucible watercrafts won’t respond with your examples. They withstand acids and antacid efficiently. This keeps your melted products pure. They stay strong at extreme warmth. The 99% boats manage up to 1700 ° C quickly. The 95% watercrafts are good for temperatures around 1600 ° C. They do not warp or fracture quickly under heat stress.

Sizes are typical for laboratory heaters. Typical sizes are 50mm, 70mm, 100mm. Widths and depths vary to match. Wall density is consistent for also home heating. The surface is smooth in and out. This quits product sticking after melting. Cleaning up is straightforward after usage.

You use them for thawing metals, glass, powders. They work well for sintering and annealing too. They fit common tube heaters perfectly. Their flat base keeps them secure. The open design permits very easy loading and dumping. They last a long time with appropriate treatment. You can recycle them sometimes. This saves cash over non reusable options. They provide reliable control for demanding laboratory job.

Applications of High Purity Rectangular 95% 99% Al2o3 Alumina Oxide Ceramic Crucible Boats for Lab Melting

High pureness rectangle-shaped alumina ceramic crucible boats deal with requiring laboratory melting tasks. These crucibles are available in 95% or 99% Al2O3 purity degrees. Higher purity means far better efficiency. Both qualities resist extremely high temperatures. They hold up against thermal shock well. Sudden temperature adjustments will not break them quickly. Their chemical inertness is crucial. They do not react with most molten materials. This keeps your samples pure. No contamination happens.

These watercrafts are perfect for melting precious metals. Gold, silver, platinum group metals require clean containers. Alumina crucibles supply that. They work well for melting different chemicals too. Changes, salts, and various other compounds thaw safely inside. Test blend is one more common job. Preparing examples for evaluation uses these boats. Ash web content determination in products is routine. High temperatures burn off organics leaving ash. Alumina boats survive this procedure.

The rectangular form supplies functional benefits. It provides a big area. Samples warm uniformly. It’s easy to load and unload samples. The form is secure. Watercrafts sit securely on heating system racks. They can be found in common sizes. Usual dimensions are 50ml, 100ml, 150ml ability. Bigger dimensions exist. Select the size suitable your heater and example amount.

Expect lengthy service life. These crucibles stand up to wear. They sustain duplicated home heating and cooling down cycles. Their firmness avoids damaging. They maintain their shape. This integrity saves laboratory expenses. You change them less typically. They handle temperatures as much as 1700 ° C for 95% purity. The 99% purity grade takes care of even higher temperatures, near 1800 ° C. This covers most lab melting demands. Alumina ceramic crucible boats are a trusted selection for regular, contamination-free results. Labs rely on them daily.

5 FAQs of High Purity Rectangular 95% 99% Al2o3 Alumina Oxide Ceramic Crucible Boats for Lab Melting

Here are five common questions about our high purity rectangular alumina ceramic crucible boats:

What are these alumina ceramic crucible boats exactly?
They are containers made for labs. You melt materials inside them. They are shaped like rectangles. This shape is called a “boat”. They are made from alumina oxide ceramic. You get two purity levels: 95% Al2O3 or 99% Al2O3. They handle very high heat well.

Why is high purity important for these crucibles?
High purity means less contamination. Impurities in the ceramic can get into your melted sample. This messes up your results. Our 95% and 99% alumina crucibles keep your samples clean. This is critical for accurate lab work like analysis or growing crystals.

How hot can I safely use these alumina boats?
The maximum temperature depends on the purity. The 95% Al2O3 boats work well up to about 1600°C (2912°F). The 99% Al2O3 boats handle even more heat. They are stable up to roughly 1700°C (3092°F). Always check the specific grade’s datasheet. Don’t exceed the rated temperature.

Can I reuse these ceramic crucibles?
Yes, you can usually reuse them many times. They are very resistant to chemicals and wear. Clean them carefully after each use. Follow proper cleaning methods for your materials. Avoid sudden temperature shocks. Let them cool down slowly. Inspect for cracks before reuse. Damaged crucibles should be replaced.

Why choose a rectangular boat shape instead of a round crucible?
The rectangular shape offers practical advantages. It fits more material surface area inside some furnaces. This is good for processes needing even heating over a flat area. It allows easier loading of flat samples or wafers. Rectangular boats also often sit more securely on furnace boats or setters. They are simply better suited for certain melting jobs.
