About Graphite - Saint Jean Carbon

There are three principal types of natural graphite, each occurring in different types of ore deposit The mineral graphite is an allotrope of carbon. Unlike diamond (another carbon allotrope), graphite is an electrical conductor, making it a semimetal. Graphite is the most stable form of carbon under standard conditions. As a result it is used in thermochemistry as the standard state for ...

Graphite 101 | Focus Graphite

Graphite is the only non-metal element that is a good conductor of electricity and heat. Its softness and streak make graphite useful in making lead for pencils. Crystals are uncommon, but when they occur, they are found as rough, six-sided (hexagonal) flakes. It breaks into minute, flexible flakes that easily slide over one another.
