You get 2 purity options: 99% or 96% light weight aluminum oxide. This high pureness makes the crucible exceptionally hard. It shakes off deterioration.

The square shape is useful. It fits nicely into heating system rooms. It stacks successfully. You can position examples conveniently inside. It’s different from rounded crucibles. This layout offers security and much better room use.

Warm resistance is its superpower. This crucible makes fun of temperatures up to 1800 ° C (3272 ° F). That’s seriously warm. It keeps its toughness. It will not thaw or warp easily. This makes it excellent for thawing steels, evaluating minerals, or sintering powders. Unexpected temperature modifications? Immaterial. It deals with thermal shock well. It resists splitting when heated or cooled down fast.

Chemicals don’t bother it much either. Acids and alkalis struggle to damage this material. It’s chemically inert for many jobs. You won’t obtain contamination screwing up your outcomes. It’s also electrically shielding. This works in lots of home heating processes.

Physically, it’s very difficult. It’s almost as tough as sapphire. This implies it lasts a long period of time. It survives misuse. It will not scratch quickly. The surface area is thick and smooth. This prevents things sticking inside. Cleaning is uncomplicated.

It’s the go-to device for exact high-temperature job. Factories utilize it for alloy screening. Labs depend on it for ash evaluation. Ceramicists employ it for shooting unique products. Jewelers thaw rare-earth elements in it. It’s reputable. It delivers regular efficiency batch after set.

5 FAQs of 99% 96% square corundum metallurgical porcelain high temperature resistance alumina ceramic crucible

What exactly is this crucible made of?
This crucible uses very pure alumina ceramic. The main types are 99% alumina or 96% alumina. Both contain corundum crystals, the same mineral as sapphire or ruby. This gives extreme hardness. The material is also called metallurgical porcelain. It means the ceramic handles high heat and chemical reactions well.

How hot can this crucible safely get?
These crucibles resist very high temperatures. The 99% alumina version handles continuous use up to about 1750°C. The 96% alumina version handles continuous use up to about 1600°C. They can briefly endure even higher peaks without damage. This makes them suitable for melting metals like gold, silver, copper, or alloys.

Why is the square shape important?
The square design is practical. It lets you fit more crucibles side-by-side inside a furnace. This saves space and energy. Square crucibles also stand firmly on a flat surface. They are less likely to tip over compared to round ones. This shape is common in labs and small foundries.

Can it handle sudden temperature changes?
Yes, thermal shock resistance is good. These alumina ceramics heat up and cool down without cracking easily. The material expands slowly under heat. This reduces stress inside the crucible during rapid heating or quenching. You can take it from a hot furnace and let it cool in air safely.

What makes it better than other crucibles?
Its purity and structure are key. High alumina content means less impurity. This prevents contamination of your melt. It also resists attack from many fluxes and molten metals very well. The dense structure stops leaks. It lasts longer than cheaper graphite or clay-graphite crucibles under harsh conditions.
