What is a carbon rod?
Carbon rod is a rod made of high purity carbon often used as an electrode where heat resistance or resistance to chemicals is needed. Carbon rods are made of a specific type of carbon known as graphite. This type of carbon is highly conductive and resistant to heat and chemicals. Carbon rods also known as carbon electrode rods are used in electrolysis and electrical experiments, spot welding, arc welding, creating electric arc for demonstration purpose,

Where to buy Carbon Rod or Graphite Electrode Rod?
If you have enough time, you want a low price educational product, or you need a few other science supplies as well, you may order carbon rods online at MiniScience.com, ScienceKitStore.com, or ChemicalStore.com. All you need is a credit card and a good shipping address.
If you don’t have much time, you need the product fast and you are not concerned about the price and traveling, then you may be able to source similar carbon rods at your local welding suppliers or hardware stores.
These carbon rods are also used in making alkaline batteries. They form the positive pole of each battery and are located in the center of AA, C and D cell batteries. Some people brake down a used battery and pull out the carbon rod, but doing that requires proper tools and protective clothing. Carbon rods can brake while removing them.
