There are many methods to manufacture diamonds in the world, but the most common method is static high-pressure high-temperature synthesis with catalysts. According to the characteristics of the synthesis technology and the crystal growth mechanism, these methods can be categorized to the following types:
Diamond is the hardest material on the earth. It has high thermal conductivity, high insulation and high chemical stability. It can be used to process non-ferrous metals such as aluminum and copper both efficiently and precisely, and is especially suitable to process hard and brittle non-metallic materials.
On September 5, 2009, Henan Polytechnic University (China) successfully synthesized an 8.2mm, 2 carats weight high quality yellow diamond.
