Abstract
A composite tile is comprised of coal dust and a pre-ceramic polymer that are mixed together and pyrolyzed to form a ceramic composite. For example, a chemical reaction during pyrolysis chemically converts at least a portion of the coal dust and pre-ceramic polymer to a fire proof ceramic composite suitable for use as a roofing tile either as pyrolyzed or as post-treated to seal cracks and pores formed during pyrolysis.
