Anthracite is so hard and pure that it is also referred to as "black diamond." It has a high carbon content and is considered the highest quality coal due to its low impurities and high energy density. Anthracite burns cleanly and efficiently, making it a popular choice for heating and industrial applications.
Anthracite coal is very hard and pure because it has undergone intense pressure and heat over millions of years during its formation, making it the most metamorphosed type of coal. Due to its high carbon content and low impurities, anthracite is often referred to as a "metamorphic rock" rather than a typical coal.
bituminous is less hard,and its dull.whereas anthracite is very hard.
Bituminous coal is relatively soft and dull, as opposed to anthracite which is hard and shiny. Anthracite is also much more dense and pure. Because of its purity (can be up to 98% carbon), Anthracite burns a very hot, smokeless flame.
Coal, particularly anthracite coal, is almost pure carbon.
Aluminium is an element, a pure substance there are no "other" names for it.

Carbon. Coal has a few different types and grades, but hard anthracite coal is almost pure carbon. Same as graphite, soot and diamonds.
Pure Play
yes it is. a dachshund is also more commonly referred to as a "wiener dog"
No.It is sedimentary, however anthracite is considered metamorphic. Graphite (chemically pure carbon) can be found in igneous rocks.
Peat is decayed vegetation probably thousands of years old but which has not been converted to coal. Lignite is called brown coal, again vegetable matter that has not become true coal. Anthracite is a very pure form of coal much valued for steam engines.

The materials formed at each step of the process are 1) Peat 2) Lignite 3) Sub-Bituminous and Bituminous Coal 4) Anthracite (may also form from oil) The final stage, which most coal does not reach, is graphite or pure carbon.
