Application of Graphite in Heating
Graphite is a form of carbon with a wide range of uses. It is one of the most widely used materials in industry, thanks to its strength and affordability. Graphite has also been used in heating elements for many years. This article outlines the various applications of graphite in heating and its advantages.
The most common type of graphite used for heating is isotropic graphite. Isotropic graphite is produced when graphite ore is heated in an electric furnace to temperatures over 3000°C. This process creates a very dense material with a uniform structure, making it ideal for heating elements.
There are many advantages to using graphite for heating elements. Graphite is an outstanding conductor of heat, meaning it can move heat quickly and effectively. This makes graphite a very efficient heating material, and it does not need to be replaced often. Graphite also does not retain warmth, allowing it to quickly cool down after turning off the heating element.
Graphite heating elements are also durable and can last for years when properly maintained. Graphite is also a fairly inexpensive material, which makes it attractive to manufacturers when compared to more expensive metals. Graphite heating elements also maintain their shape and form, making them a reliable choice for long-term use.
Graphite has also been used in other forms of heating. It is a common material used in infrared heating systems. It is also used in some of the more specialized forms of heating such as microwaves, induction heating, and infra-red saunas.
In the medical field, graphite has been used to quickly warm up patients with hypothermia. This is done by placing graphite heated blankets directly onto the patient’s skin. The material is able to transfer heat to the body quickly and can help save lives in certain medical emergencies.
To conclude, graphite is a versatile material with many applications in heating. Its low cost and efficient heat transfer make it a popular choice for heating elements. It is also a common material used in infrared heating systems, induction heating, and microwaves. Lastly, it is often used in emergency situations for heating blankets for hypothermic patients.
