Graphite is highly resistant to heat and can maintain its structure and form even at temperatures as high as 5000°F.
This makes it suitable for use in furnaces and high heat processes.
However, it is important to note that graphite is oxygen sensitive and must not be exposed to air while at elevated temperatures.
Oxidation in air starts around 500°C (932°F) and proceeds rapidly, eventually leading to structural failure if exposed repeatedly.
4 key points to know
1. High Temperature Resistance
Graphite's high thermal stability and resistance to thermal shock, oxidation, and abrasions make it a popular choice for various applications.
2. Crucibles and Insulation Materials
Graphite crucibles, for example, are known for their strong corrosion resistance to acid and alkali solutions, high mechanical strength, and long service life.
Graphite insulation materials also have excellent thermal insulation properties, minimizing heat loss and ensuring longevity.
3. Oxygen Sensitivity
Graphite must be protected from exposure to air at elevated temperatures to prevent oxidation and structural failure.
4. Versatile Applications
Its temperature-resistant properties make it a valuable material for numerous high-temperature applications.
