Specification of High Purity Al2O3 Ceramic Corundum Alumina Crucible for Laboratory Metal Melting

This crucible deals with heats in metal melting labs. It’s made from pure alumina ceramic. The product is over 99.6% light weight aluminum oxide (Al2O3). This high pureness matters. It avoids contamination of your dissolved steels. You obtain cleaner results.

The crucible withstands very high warm. Its optimum service temperature reaches 1750 ° C(3182 ° F). It handles short bursts approximately 1800 ° C (3272 ° F). This makes it appropriate for thawing lots of metals. Assume gold, silver, platinum, copper, iron alloys. It functions well for tiny laboratory batches.

Thickness is important. This crucible has high thickness, around 3.9 g/cm ³. High density implies better resistance. It withstands chemical strike from liquified steels. It resists wear gradually. The crucible lasts much longer due to this.

Thermal shock resistance is one more crucial function. It copes well with fast temperature level changes. You can warm it fast. You can cool it quickly. It won’t crack conveniently. This is crucial in laboratory job.

The product is chemically inert. It withstands acids. It stands up to alkalis. It resists most molten changes. This stability protects your melt purity. The surface area is smooth. This stops steel sticking. It makes cleaning much easier.

These crucibles are available in different dimensions. Typical dimensions hold 5ml, 10ml, 20ml, 50ml, 100ml. Bigger sizes are readily available. Choose the dimension fitting your heating system and sample amount. Manage it carefully when warm. Always use appropriate tongs.

Applications of High Purity Al2O3 Ceramic Corundum Alumina Crucible for Laboratory Metal Melting

Scientists and laboratory specialists thaw metals in crucibles. High purity Al ₂ O four ceramic corundum alumina crucibles are superb for this. They are made from really pure light weight aluminum oxide powder. This pureness matters. It quits unwanted chemicals from getting into your thawed metal sample. Keeping the example pure is essential for accurate examination results later.

These alumina crucibles handle severe warmth well. They function great past 1700 ° C. This heat resistance is necessary. Several metals melt only at extremely heats. Platinum, gold, silver, and other rare-earth elements melt inside them. So do numerous unique alloys and various other non-ferrous steels. The crucible won’t soften or break down conveniently.

Alumina crucibles are likewise very strong. They resist thermal shock relatively well. This implies warming them up fast or cooling them down quickly is typically all right. They won’t break right away. This durability makes them last much longer than some other ceramic types. You get even more uses from each crucible. This saves money in time.

Utilizing these crucibles assists protect against contamination. Iron, silicon, or alkali metals can spoil a metal example. High pureness Al two O five reduces this threat. The crucible product itself includes nearly nothing international to your thaw. This is important for research pureness and quality assurance checks. You trust your metal evaluation isn’t skewed by the container.

They are secure with molten steels. Alumina does not react easily with the majority of dissolved steels. This chemical inertness secures both your example and the crucible. The crucible stays undamaged much longer. Your steel stays cleaner. Crucibles are available in numerous sizes and shapes. You discover the appropriate one for your small laboratory heater or larger kiln. They are essential devices for clean, reliable metal melting job.

5 FAQs of High Purity Al2O3 Ceramic Corundum Alumina Crucible for Laboratory Metal Melting

Here are 5 FAQs about High Purity Al2O3 Ceramic Corundum Alumina Crucibles for Laboratory Metal Melting:

What maximum temperature can this crucible handle?
This crucible withstands temperatures up to 1750°C. It handles most common laboratory metal melting tasks. Avoid sudden temperature changes. Sudden changes might crack the crucible.

Which metals are safe to melt inside?
This crucible works well for gold, silver, copper, platinum. It handles aluminum alloys too. Avoid highly reactive metals like titanium, zirconium, alkali metals. These metals attack the alumina.

How do I clean the crucible after melting metal?
Let the crucible cool completely first. Remove any leftover metal slag carefully. Use warm water and a mild detergent. Scrub gently with a soft brush. Never use harsh abrasives. Abrasives damage the smooth surface.

Is this crucible strong? Does it last long?
Alumina ceramic is very hard and strong. It resists wear and thermal shock well. Proper care extends its life. Expect many uses under normal conditions. Rough handling shortens its life. Dropping it will likely break it.

Can I use this crucible for other high-temperature work?
Yes. Its high purity and temperature rating make it versatile. Use it for sintering small samples. Use it for calcining materials. It works for various high-heat lab processes needing chemical inertness.
