By 1896, The Carborundum Company was producing 1 million pounds of carborundum. A few carbides are covalent lattices, like carborundum (SiC), which resembles diamond. It was carved using carborundum, a modern abrasive. Carborundum grit is applied in a paste to the surface of an aluminium plate. The third word, "carborundum", is an abrasive used for industrial grinding. The tools used were seven scrapers, one chisel and a piece of carborundum stone. He discovered that overheating carborundum, as opposed to pure carbon, produced almost pure graphite. The wheel should be coarse and hard, therefore aluminium oxide or carborundum often are employed. He is known for his artwork, as well as for inventing the carborundum printmaking process. The album title is a reference to the mock-Latin aphorism Illegitimi non carborundum. Silicon required more pressure than the cat whisker contact, although not as much as carborundum. Burning coal or carborundum dust was tried. Carborundum Universal Ltd has a unit near the technopolis. In addition to his carborundum printing research, Goetz undertook extensive research on pastels.
