Carbon Crucible

Carbon crucibles come in various shapes such as cylindrical, conical, and square, and its advantages are quite remarkable.

Advantages of Carbon Crucible

Extremely strong heat resistance
It can maintain structural stability within an extremely high temperature range of 1500°C to 2200°C, which it not easy to melt or crack.

稳定的化学特性
It is not prone to react with metal melts at high temperatures, which ensures the purity of the heated substances.

Uniform thermal conductivity
It enables rapid heat transfer and is consistent heating of internal materials, which improves the efficiency of melting or reactions.

机械强度高
It is capable of withstanding the weight of the melt and certain impacts and vibrations. And it is unlikely to be damaged during handling and pouring.

Smooth surface
It doesn’t easily adhere to materials, making cleaning convenient after use, and can be reused multiple times, reducing the cost of use.

Strong adaptability
It can be matched with various heating devices such as induction furnaces to meet the usage requirements of different scenarios.

Uses of Carbon Crucible

In the field of metallurgy

You can use it to melt various metals and other non-ferrous metals as well as various alloys. It can ensure that the metal does not react with the crucible during the melting process. And it also ensures the uniform composition of the metal melt, providing high-quality raw materials for subsequent processing steps. So it is particularly suitable for the small-scale production of special alloys and precious metals.

In the laboratory and research field

In material synthesis
You can use it for high-temperature preparation of ceramic materials, nanomaterials, and composite materials, etc.

In sample processing
You can use it for burning and ashing of solid samples to remove organic impurities, and then conducting component analysis.

In chemical experiments
It can serve as reaction vessels, carrying out high-temperature molten reactions such as molten salt electrolysis, metal oxide reduction reactions. It provides a stable environment for researchers to explore new materials and study reaction mechanisms.

In glass and ceramics industry

In the production of optical glass
Its high-temperature resistance and low impurity properties ensure that the glass melt is free of bubbles and impurities. So it can improve the light transmittance and optical performance of the optical glass.

In the ceramic industry
You can use it for firing special ceramic bodies or for melting ceramic glazes. It can control the temperature precisely, which ensures the texture and appearance quality of the ceramic products.

In electronic and semiconductor industry

In the production of semiconductor materials
You can use it for the pre-treatment of semiconductor single crystals before pulling and remove the impurities within them.

In the manufacturing of electronic components
You can use it for heating treatment of electronic ceramic components such as ceramic capacitors and inductors. Or you can use carbon crucible for melting and purifying metal electrode materials such as tungsten and molybdenum. It can ensure the stability of electronic component performance and provide support for the production of them.
