How to Choose Korea Graphites

To choose your ideal graphite from Korean suppliers, there are several factors to consider. Here are some to help you:

• Type of graphite

  Graphite types are among the key factors to help you choose. They include natural and synthetic graphite. Natural graphite types are usually cheaper. This is because they are easily mined. However, they are often flaky and may have impurities. On the other hand, synthetic graphite is more expensive because the process of making them is often complex and long. Nevertheless, they are more durable since they have a solid structure.

• Purity level

  Another factor you should consider when choosing graphite is its purity level. If you will need the graphite for lubricants and refractories, then go for options with lower purity levels, such as 85% to 90%. However, if you need the material for batteries and fuel cells, opt for high-purity graphite (90% to 99%).

• Grain size

  Grain size is also a key consideration. For instance, in lithium-ion batteries and fuel cells, large-grain graphite is ideal for making anodes. On the other hand, small-grain graphite is useful in paints, lubricants, and molds.

• Application

  Graphite's end use will also be an important factor in its selection. For instance, battery manufacturers prefer synthetic graphite because of its structural integrity. On the other hand, industries that mine for natural graphite for general use such as lubricant and refractory applications, will not bother whether it's pure or synthetic.

• Mechanical strength

  In terms of mechanical strength, consider the tensile strength and elastic modulus of the material. These will determine how the material will respond in high temperatures. Typically, materials with high elastic modulus are suitable for extreme temperatures and environments.

• Supplier's ability

  Lastly, always consider the supplier's ability to provide you with a consistent and high-quality graphite material. To ensure you pick a reliable supplier, look at their online reviews and request feedback from their previous customers. Also, consider their ability to deal with your order size.
