Specification of Crucible for Laboratory 95%/ 99% Alumina Al2o3 Pot Ceramic Crucibles to Melt Platinum

Laboratories working with platinum require crucibles that handle severe heat without contamination. Alumina ceramic crucibles satisfy this need. They come in 95% and 99% pureness qualities. The 99% Al2O3 version uses superior performance for platinum. Its extremely high alumina content stands up to chemical attack. It prevents undesirable reactions with the liquified platinum. This guarantees example purity. The material withstands temperature levels approximately 1800 ° C. This is well over platinum’s melting factor. Crucibles maintain structural stability at these extreme heats. They withstand thermal shock as well. This suggests they manage quick home heating and cooling cycles well. Cracking or damaging is less likely. Crucibles are thick and non-porous. This stops liquified metal from saturating into the walls. Loss of beneficial platinum is lessened. Leakage is stopped. Surface area level of smoothness is high. Sticking is minimized. Examples launch conveniently after melting. Usual sizes include 5ml, 10ml, 15ml, 20ml, 30ml, 50ml, and 100ml capabilities. The shape is normally a round pot. A flat bottom offers stability on furnace shelves. Crucibles are single-use items. They are developed for one high-temperature melting cycle. Reuse is not suggested. Efficiency degrades after exposure to severe problems. Using a fresh crucible warranties reliability. Select the 99% alumina grade for the very best outcomes with platinum. Choose the dimension matching your particular sample volume.

Applications of Crucible for Laboratory 95%/ 99% Alumina Al2o3 Pot Ceramic Crucibles to Melt Platinum

Melting platinum requires unique crucibles. Platinum gets to extremely high temperatures. It requires a container that manages extreme warmth without failing. Platinum is likewise useful. You can not take the chance of contaminating it. Crucibles made from 95% or 99% alumina ceramic are the top choice. Alumina ceramic has a melting factor much more than platinum. This means the crucible stays strong and stable. It does not soften or damage down at platinum’s melting factor.

These alumina crucibles withstand thermal shock well. You can warm them promptly. You can cool them down. Unexpected temperature modifications usually trigger cracks. Alumina manages this stress better than several various other products. This resistance is essential for lab work entailing duplicated heating cycles.

Chemical inertness is important. Platinum needs to remain pure. High-purity alumina ceramic is extremely unreactive. It does not react with molten platinum. It does not add contaminations. The 99% alumina variation provides the highest possible purity. It is the best option for crucial platinum melting tasks. It reduces the chance of any contamination. The 95% alumina is still very good. It is a strong, cost-efficient option for lots of platinum melting applications.

These crucibles can be found in many sizes. You’ll discover little ones for gram amounts. You’ll find larger ones for larger batches. Usual shapes are high type and reduced form. The exact size depends upon your heating system and the amount of platinum. Always select a crucible dimension that fits your furnace effectively. Ensure excellent heat transfer.

Deal with these crucibles carefully. Use correct tongs. Prevent influences. Tidy them well prior to usage. Adhere to the maker’s standards for optimum temperature and heating rates. This care extends the crucible’s life. It makes sure risk-free melting of your platinum.

5 FAQs of Crucible for Laboratory 95%/ 99% Alumina Al2o3 Pot Ceramic Crucibles to Melt Platinum

What makes alumina ceramic good for melting platinum?
Alumina handles extreme heat well. Platinum melts at very high temperatures. Alumina stays stable. It resists chemical reactions with molten platinum. This keeps your platinum pure. High purity alumina adds little contamination.

What’s the maximum temperature these crucibles can take?
95% alumina crucibles handle temperatures up to 1750°C safely. 99% alumina crucibles go higher, around 1800°C. Platinum melts near 1770°C. The 99% grade is safer for this job. Always stay below the crucible’s rated max temperature.

How long do these crucibles typically last?
Lifespan varies. It depends on temperature, how long you heat it, and cooling cycles. Platinum is corrosive. Crucibles degrade faster with repeated melting. Expect fewer uses at platinum’s melting point. Inspect crucibles carefully before each use. Look for cracks or wear.

Can impurities from the crucible get into my platinum?
High-purity alumina minimizes this risk. 99% alumina is better. It has fewer impurities than 95%. Still, tiny amounts of silica or other oxides might leach out over time. This is especially true at high temperatures. Use the highest purity crucible possible for critical platinum work.

Is 95% or 99% alumina better for melting platinum?
99% alumina is generally better. It handles higher temperatures safely. Platinum melts very hot. 99% alumina resists thermal shock better. It also has fewer impurities. This means less chance of contaminating your platinum. Use 95% alumina only for lower temperatures or less critical tasks.
