Abstract: PDC resins are mixed with various sources of carbon to form electrodes through pyrolysis of the mixture of PDC resins and coal dust derived materials with or without other sources of carbon, substrates and the like. For example, a PDC resin-coal dust mixture produces a material for use as an anode in lithium ion batteries and supercapacitors when pyrolyzed to form a porous, electrically conductive ceramic composite.

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.

Abstract: Methods, processes, systems, devices and apparatus are provided for additive manufacture resulting in the 3D printing of ceramic materials and components with a thickness greater than three millimeters (3 mm). A sulfur-free 3D printable formulation comprises a liquid inorganic polymer resin using Stereolithograpy (SLA) printers and Digital Light Processing (DLP) curing of the polymer resin via the chemical bonding of the materials rather than sintering. Thus, the process has shorter manufacturing intervals, significantly lower energy use and produces larger scale ceramic components having less linear shrinkage, less mass loss and high ceramic yield with no corrosive sulfur compounds present in the ceramic component.

Abstract: A complex composite particle is made of a coal dust and binder composite that is pyrolyzed. Constituent portions of the composite react together causing the particles to increase in density and reduce in size during pyrolyzation, yielding a particle suitable for use as a proppant or in a composite structure.

Abstract: A polymer derived ceramic precursor is selected and mixed with a contaminated recycled electrode material or materials. The mixture is pyrolyzed to form a ceramic or ceramic-carbon composite, reduced to a powder and formed into an electrode of a battery, such as a lithium ion battery.
