À quoi sert le creuset en carbure de silicium ?

Produits en carbone graphite

Silicon carbide crucible is used for melting and refining metals. It is more durable than traditional ceramic crucibles and have many advantages, such as high-temperature resistance and thermal conductivity.

In this blog post, we will discuss the benefits of using them, how to choose the right one, and their advantages of them over traditional materials.


Qu'est-ce qu'un creuset en carbure de silicium ?

It is mainly made of graphite lamellaire and carbon bonded as raw materials.  Manufacturers press the processus de pressage isostatique according to a certain proportion.

Their structure is dense, preventing heat loss to the surrounding environment. It is very durable and can withstand temperatures up to 1700 degrees Celsius.

This makes it ideal for smelting and refining metals and alloys.

They are also known for their excellent thermal conductivity. This means it can maintain a consistent temperature throughout the melting and refining process.

They come in many shapes and sizes, and the suppliers can customize them to meet the user’s needs.

Silicon carbide crucibles are commonly used in metal smelting operations, such as copper, aluminum, lead, zinc, other non-ferrous metals, medium carbon steel, rare metal alloys, etc.

They’re also resistant to wear and corrosion and withstand thermal shock, which means you can run them through use without having to replace them frequently.

Métallurgie et fonderies :

In metallurgy and foundry, they are widely used for melting, casting, and refining all kinds of metals, including ferrous and non-ferrous alloys ininduction furnace.

Due to their high-temperature resistance and excellent thermal conductivity, they can withstand extremely high temperatures and provide efficient heat transfer, ensuring optimal metal melting and casting processes.

At the same time, the non-reactivity of silicon carbide prevents contamination and ensures the purity and quality of the molten metal.

Verre et céramique :

They are essential for producing glassware, ceramic components, and other high-temperature materials. Its excellent thermal shock resistance allows it to withstand rapid temperature changes without cracking or cracking.

They are can subject to extreme heating and cooling cycles. Its outstanding durability ensures reliable performance and consistent results, making it the first choice of artisans, glassmakers, and potters.

Laboratoire de chimie et recherche :

These crucibles heat, mix, and react chemicals in chemical labs and research facilities due to their excellent thermal conductivity and corrosion resistance against acids, bases, and reactive substances. The inert nature of silicon carbide prevents contamination and ensures accurate experiments.

Moreover, their high-temperature resistance makes them essential for scientists and researchers studying high-temperature reactions and materials, as they can withstand harsh lab conditions.

Fonderie de bijoux et de métaux précieux :

Gold, silver, platinum, and other precious metals are melted and cast in silicon carbide crucibles because of their ability to withstand the high temperatures required for metalworking. They ensure even heat distribution, precisely facilitating the melting and casting process.

It also has excellent thermal insulation, allowing for controlled cooling and solidification of molten metal. This results in high-quality, well-formed jewelry pieces and precise castings of intricate designs, satisfying the needs of jewelry makers and metal craftsmen.


Avantages de l'utilisation

  • Il a un niveau élevé de conductivité thermique et réduit le temps de fusion des métaux ou des alliages.
  • Il présente une forte résistance aux chocs thermiques et ne se brise pas, même en cas de refroidissement et de réchauffement rapides au cours du processus de fusion.
  • Il a les mêmes performances que le graphite, de sorte qu'il ne pollue pas la matière en fusion et que la quantité de scories métalliques adhérant à la paroi interne est faible.
  • Grâce à sa conduction thermique rapide, il permet d'économiser du carburant, de réduire la pollution due aux gaz d'échappement et de protéger l'environnement.
  • Has strong resistance to chemical and is not easily corroded.
  • Les creuset a une structure compacte, une faible porosité et une longue durée de vie, atteignant six mois en utilisation régulière.


There are many specifications of silicon carbide crucibles, and the prices are also different. So please customize it according to your needs. It would be best to store The crucible in a dry environment, and workers must preheat it to 150-200 degrees Celsius before use and then add materials. Their performance of them can meet your production needs.
