Singular graphite

Plural uncountable

graphite (uncountable)

  1. An allotrope of carbon consisting of planes of carbon atoms arranged in hexagonal arrays with the planes stacked loosely. Used as a dry lubricant, and in lead pencils. Is edible.
  2. A composite plastic made with graphite fibers noted for light weight strength and stiffness.
  3. A grey colour.

The mineral graphite is one of the allotropes of carbon. It was named by Abraham Gottlob Werner in 1789 from the Greek γραφειν (graphein): "to draw/write", for its use in pencils, where it is commonly called lead, as distinguished from the actual metallic element lead. Unlike diamond (another carbon allotrope), graphite is an electrical conductor, a semimetal, and can be used, for instance, in the electrodes of an arc lamp. Graphite holds the distinction of being the most stable form of carbon under standard conditions. Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds. Graphite may be considered the highest grade of coal, just above anthracite and alternatively called meta-anthracite, although it is not normally used as fuel because it is hard to ignite.

There are three principal types of natural graphite, each occurring in different types of ore deposit:

  1. Crystalline flake graphite (or flake graphite for short) occurs as isolated, flat, plate-like particles with hexagonal edges if unbroken and when broken the edges can be irregular or angular;
  2. Amorphous graphite occurs as fine particles and is the result of thermal metamorphism of coal, the last stage of coalification, and is sometimes called meta-anthracite. Very fine flake graphite is sometimes called amorphous in the trade;
  3. Lump graphite (also called vein graphite) occurs in fissure veins or fractures and appears as massive platy intergrowths of fibrous or acicular crystalline aggregates, and is probably hydrothermal in origin.

Highly Ordered Pyrolytic Graphite or Highly Oriented Pyrolytic Graphite (HOPG) refers to graphite with an angular spread of the between the graphite sheets of less than 1°. This highest-quality synthetic form is used in scientific research. The name "graphite fiber" is also sometimes used to refer to carbon fiber or carbon fiber-reinforced polymer.

Is graphite powder harmful if inhaled into the lungs?
Q. If working with with graphite powder, the fine particles can enter the lungs. But is it harmful?Even if one is constantly touching the graphite powder, does it cause any harm to the skin?

A. I've read some recent research that carbon nanotubes (made from sheets of graphite rolled up into tubes) can cause symptoms similar to mesothelioma (aka, the lung cancer you get from asbestos). I would definitely wear gloves when you handle it (preferably made from nitrile, and not latex as graphite could penetrate latex) and try not to breathe it in. Maybe you could wear one of those masks that people wear when they do woodworking that filters the air. I would also wear some sort of eye protection (safety glasses with side shields or goggles). The problem with carbon in this form (to contradict the first answerer) is that your body cannot use it or break it down to eliminate it as it can for many other chemicals/toxins you might… [cont.]

How do I blend my graphite pencils properly?
Q. Everytime I try to blend anything, to give that smooth look, I can see streaks of pencil marks throughout it. Is it the type of paper I am using (I got it at an art store, so I doubt it's that, though it does seem a bit grainy) or is there some trick to blending graphite pencils? I've tried cotton bud and cotton balls, and my finger to blend.

A. So, you want your pencil strokes to be blended to a perfectly smooth, almost solid - look? Pick out the softest graphites you have, and as for paper, I would not use a very grainy/coarse paper (like news print) Go for drawing paper, rather than sketching paper. Try to find one with a nice smooth marble feel. I assume you are using blending stumps? If not, you will need those. A good technique I have used in the past: Do not hold your pencil like you would if you were writing. You are centering all the force onto that one point, and it makes permanent impressions in the paper. Instead, hold your pencil to its side. Like you would if you were shading a large area. This means you will be primarily pushing down on the pencil with your thumb… [cont.]

Why is it possible to write on paper with graphite and not diamonds?
Q. If one examines the structures of graphite and diamonds, one would see that they are both made up of carbon atoms. However what makes it possible to write on paper with graphite?? (I hope that makes sense)
Asked by My name is - Fri Sep 14 00:21:02 2007 - - 5 Answers - 0 Comments

A. When you write on paper with graphite, it flakes off (because graphite is arranged in loosely associated layers of carbon that shear apart quite easily) and stick to the paper in a dust. Diamond is arranged in a crystal, the crystal is far, far too strong to come apart from the force of friction with paper, so it doesn't leave any visible carbon behind.
