How much heat can a graphite crucible handle?

If you want to learn more, please visit our website.

A graphite crucible can handle high temperatures and is resistant to both chemical and thermal shock. The temperature range for a graphite crucible can go as high as °F (°C). High-purity graphite crucibles are designed to withstand temperatures up to degrees Celsius ( degrees Fahrenheit). This makes them ideal for melting metals such as aluminum, copper, and brass without the risk of contamination or damage due to heat stress. These crucibles usually come with lids that lock in place during use, making it easier to maintain an even temperature while the molten material cools quickly after use.

Using high-purity graphite crucibles has several benefits over clay or ceramic crucibles. They have enhanced corrosion resistance, improved strength and stability at higher temperatures, and extended service life due to their chemical inertness. This means that the graphite won't react with any substances being melted down inside it. Additionally, high-purity graphite crucibles don't require additional linings for protection against harmful elements like sulfur, which can cause premature failure in certain materials if exposed for too long at excessive temperatures.

The rate of temperature change is also an important factor to consider when choosing a crucible. Some crucible types are better at handling rapid temperature changes than others. Crucibles with high carbon content in the graphite have high thermal conductivity and non-wetability, which imparts high thermal shock resistance. This is critical for foundry applications where temperatures can change by several hundred degrees in seconds.

Graphite crucibles are also used in E-Beam sources, where they form a thermal barrier between the melt and water-cooled hearth. These crucibles undergo high purification before reaching the customer, ensuring low levels of contaminants. They can withstand as many as 400 evaporation cycles.

Graphite crucibles can be used to melt alloys such as gold, silver, platinum, and other precious metals, and they have a long service life. They are widely used in non-ferrous metal foundries for grinding and casting metals like gold, silver, brass, aluminum, copper, zinc, and lead. They have excellent thermal stability and can withstand temperatures up to °F (°C).

Carbon-bonded and ceramic-bonded clay graphite and silicon carbide crucibles are also commonly used for melting and holding various metals. These crucibles are used for melting aluminum and aluminum alloys, aluminum-bronze, copper and copper-based alloys, cupro-nickel and nickel-bronze alloys, precious metals, zinc, zinc oxide, and even cast iron. The temperature range for these crucibles is typically from 400°C/750°F to °C/°F.
