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

These alumina ceramic crucible boats serve labs well. They come rectangular. High purity options exist. You get 95% or 99% Al2O3. This matters. Pure alumina handles extreme heat. It withstands sudden temperature changes. Crucibles stay stable. They don’t crack easily. Chemical resistance is strong. Acids and bases don’t attack them. This is vital for melting.

Lab technicians use them daily. Melting metals is common. Gold, silver, platinum need these boats. Precious metals require clean melting. Alumina keeps the melt pure. Contamination risk is low. Ceramic won’t react. Samples stay accurate.

Industrial labs rely on them too. Testing new alloys happens often. Researchers melt small batches. They study material behavior. The crucibles hold up. Repeated use is possible. Longevity saves money.

Firing ceramics is another use. Small glazes get tested. Powder samples need sintering. The crucible boats work perfectly. High temperatures are no problem. They go beyond 1700°C easily. Thermal shock resistance helps. Moving hot items is safer.

Handling is straightforward. The rectangular shape aids pouring. Solidifying melts release easily. Cleaning is simple. A quick wash often suffices. Storing them takes little space.

Durability is a key advantage. Alumina ceramic is tough. It resists wear and tear. Crucibles last many cycles. Lab budgets appreciate this. Replacing them less saves costs.

Performance is reliable. Consistent results matter. These boats deliver every time. They handle corrosive fluxes. Borax and others work fine. Stability ensures process control.

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

What are these crucible boats made of?
These boats are crafted from high-purity alumina ceramic. You get two purity levels: 95% Al2O3 or 99% Al2O3. This means mainly aluminum oxide. This material is very tough and handles extreme heat well.

How hot can I safely use them?
The maximum temperature depends on the purity. The 95% Al2O3 boats typically handle continuous use up to about 1600°C (2912°F). The 99% Al2O3 boats handle even higher temperatures, often up to 1700°C (3092°F) or sometimes more. Always check the specific maker’s rating for your boat.

Will chemicals damage the crucible?
Alumina ceramic resists most chemicals very well. This includes many acids and bases. It also resists molten metals. Strong alkalis like sodium hydroxide or hydrofluoric acid can attack it. Avoid these. Check chemical compatibility for your specific material.

Can they handle sudden temperature changes?
Alumina ceramic has good thermal shock resistance. This means it generally copes well with heating and cooling cycles. Still, avoid extreme, rapid temperature swings. Always heat up and cool down gradually when possible. This prevents cracks.

Why choose 99% over 95% alumina?
Higher purity (99% Al2O3) offers better performance. It withstands higher temperatures. It resists wear and chemical attack better. It also lasts longer under tough conditions. It costs more. The 95% Al2O3 is a good, more affordable option for many standard lab melting tasks below 1600°C.
