Specification of High temperature Al2O3 alumina melting ceramic crucible

This alumina crucible takes care of extreme heat. It’s made from high-purity Al2O3 ceramic. This material is exceptionally difficult. It holds up against temperatures approximately 1800 ° C. This crucible functions perfectly for melting steels. It’s optimal for gold, silver, platinum, and various other alloys. The crucible withstands rust well. Acids and bases don’t damage it conveniently. This makes it dependable for many chemical procedures.

Its thickness is extremely high. This quits liquified steel from taking in. Your melts keep pure. Crucible contamination is reduced. This ceramic deals with sudden temperature level shifts. Relocating from hot to cold won’t fracture it easily. It makes it through repeated heating cycles. This crucible supplies long life span.

The pureness degree is 99.5% Al2O3. This ensures consistent performance. The crucible surface is smooth. This makes cleaning simple. Slag and residue do not stick hard. You get a clean surface for the following thaw. These crucibles come in various sizes. Choose the capability you require. They fit standard lab heaters. They also work in industrial factories.

Use it for accurate laboratory screening. Use it for little set production. Jewelers cast precious metals with it. Researchers analyze products at high heat. It handles oxidizing atmospheres well. It executes accurately in inert gas setups. This crucible is a reliable workhorse. It takes on requiring melting tasks. It offers stable results whenever.

Applications of High temperature Al2O3 alumina melting ceramic crucible

Heat alumina ceramic crucibles deal with extreme warm. They work well over 1700 ° C. This makes them important in many tough jobs. Factories utilize them daily. Employees put liquified steels like steel, iron, copper, or brass right into these crucibles. The crucible holds the warm steel without breaking down. It maintains the metal pure during melting.

Labs require these crucibles too. Scientists warm samples to extremely high temperatures. They research materials or examine brand-new formulas. The alumina crucible doesn’t react with the majority of chemicals. It provides tidy outcomes. Glass manufacturers depend on them. Melting glass requires intense warmth. Alumina crucibles endure the heating system conditions. They don’t add impurities to the glass melt.

Chemical handling plants use them. Workers warmth corrosive chemicals or salts. Alumina stands up to chemical strike. It lasts longer than various other materials. The crucibles are solid. They resist thermal shock. Heating and cooling down cycles take place often. They don’t fracture quickly. This toughness conserves cash. Factories replace crucibles less often.

Accuracy casting uses them. Workers pour exact quantities of super-heated steel alloys. The crucible form remains true. It doesn’t warp under heat. This makes certain accurate castings. Alumina crucibles are crucial tools. They take care of the most popular, most hostile tasks accurately. Industries count on them for consistent efficiency.

5 FAQs of High temperature Al2O3 alumina melting ceramic crucible

Here are 5 key questions about high temperature Al2O3 alumina melting ceramic crucibles:

What exactly is this crucible made from?
This crucible is made from Al2O3 alumina ceramic. Alumina is a very hard material. It handles extreme heat well. It resists chemical corrosion effectively. This makes it strong for melting metals.

How hot can this crucible really get?
These alumina crucibles handle very high temperatures. They work reliably up to about 1800°C (3272°F). Some special grades go higher, near 2000°C (3632°F). Check your specific crucible’s rating. Never exceed its maximum temperature.

Why pick alumina over other crucible materials?
Alumina offers big advantages. It withstands much higher heat than graphite or clay. It resists chemical attack from molten metals better than quartz. It doesn’t contaminate melts like some metals can. It provides excellent thermal stability for demanding jobs.

Can it crack from sudden temperature changes?
Yes, thermal shock is a risk. Alumina expands and contracts with heat changes. Sudden, extreme shifts can cause cracks. Avoid rapid heating or cooling. Preheat the crucible slowly. Let it cool down slowly after use. This protects it from damage.

How should I handle and care for it?
Handle alumina crucibles carefully. They are strong but brittle. Impacts can chip or break them. Always use proper tongs. Never use metal tools directly inside. Inspect it before each use for cracks or damage. Clean out residues gently. Store it safely away from knocks.
