What is the ignition temperature of charcoal briquettes?

Answer 1

The mineral graphite has a varying burn point and cant be determined exactly. It has a melt and vaporization point however. Hear I have a little info on graphite...

The mineral graphite is one of the allotropes of carbon. It was named by Abraham Gottlob Werner in 1789 from the Greek γράφειν (graphein): "to draw/write", for its use in pencils, where it is commonly called lead (not to be confused with the metallic element lead). Unlikediamond (another carbon allotrope), graphite is an electrical conductor, a semimetal. Thus, e.g., it is useful in arc lamp electrodes. Graphite is the most stable form of carbon understandard 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 oredeposit:

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 metamorphismof 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 between the graphite sheets of less than 1°. This highest-quality synthetic form is used in scientific research.[3] The name "graphite fiber" is also sometimes used to refer to carbon fiber or carbon fiber-reinforced polymer Graphite

Answer 2

It really depends on what kind brand your using. Most charcoal burns anywhere from 200-400 degrees F although some charcoal can burn over 1000 degrees.

Answer 3

the ignition temperature of charcoal is around 380C with max temps upto 1000C

Answer 4

A charcoal forge can get hot enough to melt copper. Copper melts at 1983 degrees F. So the forge can get at least as hot as that, but probably much hotter.
