Specification of Flat Bottom / Curved 5ml – 2000ml Alumina Al2o3 Ceramic Porcelain Crucible for Furnace

Here’s the spec for our alumina ceramic crucibles:

These crucibles are made from high-purity alumina ceramic (Al2O3). They can be found in two bottom designs: flat bottom or curved base. Pick what fits your furnace configuration best. Capabilities vary widely from little 5ml sizes up to big 2000ml dimensions. We have the dimension you most likely demand.

The alumina product deals with severe warm extremely well. These crucibles stand up to temperature levels up to 1750 ° C (3182 ° F). This makes them ideal for demanding heater job. They resist abrupt temperature modifications successfully. You will not stress over thermal shock splitting them conveniently. They also stand up to chemical attack from several changes and molten products. This alumina is extremely difficult. It withstands wear and abrasion in time. Your crucible remains strong through repeated use.

The surface area is smooth throughout. This smoothness avoids samples from sticking. It additionally makes cleaning much simpler after your tests. These crucibles are thick. Their low porosity stops products from soaking in. You get exact results pursue run. They are electrically shielding. This residential property is essential for many home heating procedures.

You can make use of these alumina crucibles for many jobs. They help melting metals, firing ceramics, analyzing ash web content, and basic high-temperature laboratory work. They suit muffle heaters, tube furnaces, and other high-heat devices. Manage them with care. They are difficult but can break if gone down. Always utilize correct tongs for warm crucibles.

5 FAQs of Flat Bottom / Curved 5ml – 2000ml Alumina Al2o3 Ceramic Porcelain Crucible for Furnace

Flat Bottom / Curved 5ml – 2000ml Alumina Ceramic Crucible FAQs

What temperature can these crucibles handle?
Our alumina ceramic crucibles withstand very high heat. They work reliably up to 1750°C (3182°F). This makes them perfect for furnace work, melting metals, and analyzing ash. They handle intense heat without breaking down.

Do these crucibles resist chemicals?
Yes, alumina ceramic offers strong chemical resistance. It handles acids and bases well. It’s stable against many molten metals and fluxes. This crucible won’t easily react with your samples. It keeps your results accurate.

Can these crucibles handle sudden temperature changes?
Alumina ceramic resists thermal shock better than many materials. But extreme, rapid changes can still cause cracks. Avoid plunging a hot crucible into cold water. Let it cool slowly inside the furnace. This practice is safest. It extends the crucible’s life.

How do I clean an alumina ceramic crucible?
Cleaning is usually straightforward. Use hot water and a brush after the crucible cools completely. For stubborn residue, soak it in dilute acid like HCl. Avoid harsh abrasives or mechanical scraping. They can damage the smooth surface. Proper cleaning keeps your crucible ready for the next use.

What size crucible should I choose?
Select a size based on your sample amount. Your sample should fill no more than two-thirds of the crucible’s volume. This prevents spills during heating. It also allows space for any sample expansion. Consider the furnace chamber size too. The crucible must fit comfortably inside.
