Latest Patents
One of Hardcastle's latest patents is titled "Process for making porous graphite and articles produced therefrom." This innovative process allows for the production of solid, porous graphites with a more uniform density gradient throughout the final product. By utilizing a pressure drop during processing, the method induces boiling and varies the processing pressure between an initial pressure exceeding 1000 psig and a final processing pressure that generally exceeds the initial pressure. The techniques employed enable additional viscosity manipulation and improved density gradient characteristics, resulting in final products with bulk thermal conductivities ranging from 90-300 W/mK and apparent densities from about 0.678 g/cc to 1.5 g/cc.
Another significant patent is "Process for making carbon foam induced by process depressurization." This process focuses on producing molded pitch-based foam with a uniform density gradient. Similar to his graphite process, it utilizes a pressure drop to induce foaming, allowing for enhanced viscosity manipulation and improved density characteristics in the final product.
