Latest Patents

One of Hans Spengler's 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 softening start between 200°C and 300°C, and an oxygen content exceeding 2% by weight. This innovative carbon powder can be used for the production of shaped carbon bodies without the need for 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 by Spengler is related to coal tar pitch. He developed an isotropic coal tar pitch with a low content of carcinogenic compounds. This pitch is prepared by distilling coal tar in an evaporator at a temperature range of 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, making it suitable for use as a binding and impregnating agent in construction materials or as a varnish.
