Carbon black particles are usually spherical in shape and less regularly crystalline than graphite Carbon black changes into graphite if heated at 3000° C 5400° F for a prolonged period Among the most finely divided materials known carbon blacks vary widely in particle size depending on the process by which they are made
Synthetic graphite is a unique material that is often used for different industrial purpose It is highly purified in terms of carbon content and is known for its ability to withstand high temperatures and corrosion Those characteristics make it a great option for highly specialized industries that need predictable results from their carbon
A process to make synthetic graphite was invented by Edward Goodrich Acheson 1856–1931 In the mid1890s Acheson discovered that overheating carborundum which he is also credited with discovering produced almost pure graphite While studying the effects of high temperature on carborundum he had found that silicon vaporizes at about
Graphite fibres of considerable tensile strength are obtained by carbonizing natural and synthetic organic fibres Carbon products are obtained by heating coal to give coke natural gas to give blacks or carbonaceous material of vegetable or animal origin such as wood or bone to give charcoal at elevated temperatures in the presence of
Synthetic diamond crystals were obtained in the 1950’s from graphite powder mixed with Ni The mixture was pressed into small 2–3 cm disks which were then heated to 2000°3000°C at pressures of 100000–200000 atmospheres Under these conditions graphite is converted into diamond
