Graphite primarily consists of carbon, which is its main constituent. However, it can also contain trace amounts of other minerals and elements such as silica, aluminum, iron, and various impurities, depending on its source. These impurities can affect the properties and applications of graphite. Generally, the purity and crystalline structure of graphite determine its quality and suitability for various uses.
Carbon
Graphite schist is primarily composed of the mineral graphite, which gives it its characteristic dark color. It also contains other minerals like quartz, mica, and feldspar, along with variable amounts of other accessory minerals depending on the specific geological formation.
In a black pen graphite is used.
yes all of them are minerals.Another AnswerNone of them are minerals: coal, diamonds and graphite are formed from the mineral carbon. There is a class of minerals, according to Wikipedia: "The halide minerals are the group of minerals forming the natural salts."
Volcano + Minerals
Pencils contain graphite, which is a crystalline form of carbon. Graphite is not considered a rock or mineral, as it is composed solely of carbon atoms.
The part of the pencil that does the actual writing, called the pencil lead, is actually made of a mineral called graphite.
cast iron, aluminum, graphite and magnesium
patroleum and graphite. sometimes silver is in it too!
Gold, graphite, halite
graphite, clay, bauxite, etc.
Graphite is a nonsilicate mineral composed primarily of carbon. It does not contain silicate minerals in its chemical composition.
