carborundum's Usage Examples:

In addition to the above gaseous rectifiers of oscillations it has been found that several crystals, such as carborundum (carbide of silicon), hessite, anastase and many others possess a unilateral conductivity and enable us to rectify trains of oscillations into continuous currents which can affect a telephone.

Carborundum was applied by Engels in 1899, firebricks being washed with carborundum paste and then baked.

Acheson, in 1896, patented an application of his, carborundum process to graphite manufacture, and in 1899 the International Acheson Graphite Co.

Many of the furnaces now in constant use depend mainly on this principle, a core of granular carbon fragments stamped together in the direct line between the electrodes, as in Acheson's carborundum furnace, being substituted for the carbon pencils.

It combines directly with silicon, at the temperature of the electric furnace, yielding carborundum, SiC; and H.

The articles are slacked transversely in a furnace, each being packed in granular coke and covered with carborundum.

See also German Patent 108817 for the production of crystallized silicon from silica and carborundum.

Wheels of carborundum are also used.

Engineers and other craftsmen make extensive use of abrasion, effected by the aid of such abrasives as emery and carborundum, in shaping, finishing and polishing their work.

For silicon carbide see carborundum.

Chrissie Hynde, on the other hand, is the sandpaper of the veggie movement, the carborundum stone, the nutmeg grater.

Calcium carbide, graphite, phosphorus and carborundum are now extensively manufactured by the operations outlined above.
