Title: Winfried Boenigk: Innovator in Carbon Materials
Introduction
Winfried Boenigk is a notable inventor based in Olfen, Germany. He has made significant contributions to the field of carbon materials, holding a total of 3 patents. His work focuses on the production and application of innovative carbon powders and coal tar pitches.
Latest Patents
One of his latest patents is for a sinterable carbon powder and method of its production. This carbon powder contains 40 to 75% by weight QI or more than 90% by weight TI, with an optical anisotropy of less than 50% by volume. It has a start of softening between 200°C and 300°C, and an oxygen content of more than 2% by weight. This powder can be used for the production of shaped carbon bodies without a binding agent. The production method involves distillation from a bituminous product at a maximum of 5 mbars and a final temperature of at least 400°C, followed by grinding the distillation residue to a particle size of less than 30 micrometers and oxidation of the powder into the particle core.
Another significant patent is related to coal tar pitch. Boenigk's isotropic coal tar pitch has a low content of carcinogenic compounds. It is prepared by distilling coal tar pitch in an evaporator with a specific evaporator surface of 330 to 10,000 m²/m³, at temperatures ranging from 300°C to 380°C, under a pressure not exceeding 1 mbar. The resulting isotropic pitch contains less than 50 ppm of benzo[a]pyrene and is suitable for use as a binding and impregnating agent, as well as a protective agent in construction materials or as a varnish.
