The extensive use of graphite in industries across the world due to its impressive characteristics is not something new. Graphite tubes are used by depositing samples in them and heating them to the point of vaporization and atomization. Why is graphite used to manufacture these tubes? Here are a few points to help answer this question;
- It has a relatively lower density as compared to other metals.
- Graphite is a material with a very high melting point, so industries prefer using it for various purposes.
- It is increasingly insoluble in water and organic solvents, making it useful for the casting industry.
- Graphite is sort of a natural lubricant with a soft and slippery surface.
- It is an excellent conductor of electricity as electrons can travel anywhere throughout the graphite sheets.
Applications of Graphite Tubes
We live in a technologically advanced world where everything is readily available on the internet at affordable prices. As a factory owner, you can easily place online orders or look at potentially well-known graphite tube suppliers. Various tubes are available with equally differing dimensions to help with unique applications. Some of the usages of graphite tubes are as follows;
- Fluxing and injection tubes
- Heating elements
- Boats
- Heat exchangers
- Furnace parts
Types of Graphite Tubes
The three different types of graphite tubes being used in the industries are as follows;
- Resin Bonded Graphite Tube: This one is extruded into desirable sizes and dimensions after combining graphite flour with a resin binder. This results in a non-porous tube that is available at reasonable rates.
- Carbon Bonded Graphite Tube: This is manufactured using a combination of resin, graphite flour, and lubricants. It is highly resistant to thermal and mechanical shocks. Its production requires little energy costs making it relatively cheaper than fully graphitized tubes.
- Fully Graphitized Tubes: This one has a low thermal expansion rate coupled with increased flexibility and ductility. It is made from the same raw materials as the carbon bonded tube. However, fully graphitized tubes are heated at the temperature of 2800 degrees Celsius in a furnace.
