Specification of High Temperature Resistant Black Si3n4 Ceramic Silicon Nitride Crucible

This black silicon nitride crucible handles extreme heat. It withstands temperatures up to 1650°C constantly. Short bursts reach even higher, around 1800°C. This makes it perfect for demanding jobs like melting metals or sintering powders. You need something tough for these tasks.

The material itself is very strong. Silicon nitride ceramic resists breaking under stress. It also handles quick temperature changes well. You won’t see cracks forming easily when heating or cooling fast. This durability means your crucible lasts longer. You save money over time.

Chemical resistance is another big plus. This crucible doesn’t react with most molten metals. It also ignores harsh acids and strong alkalis well. This keeps your materials pure. Contamination ruins experiments and production runs. You get reliable results.

Its smooth surface is important too. This makes cleaning simple after use. You won’t find material sticking inside easily. Loading powders is also straightforward. The surface finish helps prevent contamination sticking around.

Handling is designed for safety. The walls are thick enough for strength. The shape is stable to prevent tipping. You work confidently with hot materials inside. It’s built for lab furnaces or industrial kilns. The design fits standard equipment setups.

Applications of High Temperature Resistant Black Si3n4 Ceramic Silicon Nitride Crucible

This black silicon nitride ceramic crucible handles extreme heat exceptionally well. Made from Si3N4, it withstands temperatures soaring past 1800°C. That’s much hotter than many metals melt. Its strength stays high even when things get really hot. This crucible laughs off sudden temperature shocks. Heating it fast or cooling it quickly won’t crack it. That reliability is crucial.

It fights off chemical attacks too. Molten metals, especially reactive ones like aluminum or titanium, don’t damage it. Harsh salts and strong bases barely touch it. This chemical toughness makes it last longer than many alternatives. You get more uses before needing replacement. It saves money over time.

The material doesn’t conduct electricity well. This matters for certain heating methods. Crucibles need electrical insulation sometimes. This one provides it naturally. Its surface stays smooth and dense. Nothing sticks easily. Cleaning leftover material is simpler. You keep the crucible cleaner for the next job.

Look at semiconductor manufacturing. It’s perfect for melting ultra-pure silicon. It handles the heat and keeps the silicon clean. No contamination happens. Crystal growers use it too. Pulling big, shiny crystals from melts needs a stable, non-reactive container. This crucible delivers that stability.

Metals research labs rely on it. Scientists melt alloys or study casting processes. They need a crucible that won’t add impurities. This one keeps the metal pure. Its resistance to molten salts is key for battery material testing. Handling corrosive fluxes in metallurgy is another job it handles well.

Its toughness means it survives rough handling. Loading, unloading, thermal cycling – it endures. You get consistent performance run after run. It lasts for many heating cycles. That durability is a big advantage. Industries needing reliable, high-temperature processing find this crucible indispensable.

5 FAQs of High Temperature Resistant Black Si3n4 Ceramic Silicon Nitride Crucible

What is a silicon nitride crucible?
It’s a container made from silicon nitride ceramic. This material handles extreme heat well. It holds metals or other materials during high temperature processes. You use it for melting, casting, or heat treatment.

Why is it so heat resistant?
Silicon nitride ceramic has strong chemical bonds. These bonds don’t break easily under high heat. The material also resists thermal shock. This means it won’t crack fast when temperature changes suddenly. It’s much tougher than regular ceramics or graphite.

How hot can it really get?
This crucible works reliably long-term up to about 1400°C (2550°F). Short bursts can go even higher, maybe 1600°C (2910°F). Don’t push it past its limit for too long. Check the specific product details for exact numbers.

What is it mainly used for?
People use it for melting precious metals like gold, silver, platinum. It’s also good for certain alloys. Labs use it for research under high heat. It works well in vacuum furnaces or inert gas atmospheres. It handles harsh conditions better than many other materials.

How long will it last?
That depends on how you use it. The temperature matters a lot. The type of material you melt matters too. How often you heat and cool it matters. Proper care helps it last longer. Expect many heating cycles. It lasts much longer than graphite or alumina in tough jobs.
