One of the earliest notable uses of the electric furnace in a large electro-chemical industry was for the production of carborundum, a carbide of silicon, which is remarkably useful as an abrasive, being available in the manufacture of grinding stones and other like purposes to replace emery and corundum.
He then informed the "MAYBE" as well as the "YES" disciples that if they wanted to study with him in this or in any future lifetime, they should prepare to move to Silicon Valley. Several hundred disciples made the move and attended Rama's first gathering in Palo Alto, California.
The remaining six, including carbon, silicon, sulphur, have not any general appellation. The gas oxygen is considered as by far the most abundant substance in our globe. It constitutes a fifth part of our atmosphere, a third part of water, and a large proportion of every kind of rock in the crust of the earth.
You couldn't do better. But I'll keep an eye on you, and perhaps I'll be able to help you a little, too." I thanked him gratefully. A famous artist, who started out in youth to embrace a military career and who failed to pass an examination at West Point, is said to have remarked that if silicon had been a gas he would have been a soldier.
It is supplied in small quantities in nearly all of our foods, and therefore we must take it for granted that it is necessary, although we are in the dark as to its uses. It is very abundant in various rocks. The cereals are especially rich in silicon. In wheat it is found in the bran and is removed from the white flour.
Or, if they could work undetected for a short while, they could drill through the shell of a space station. Scralabus primus was the scientific name of the creature, but the fact that it looked like a silicon armadillo had given it the popular name of "silly dilly." Apart from its desire for oxygen it was harmless. Koa reported, "Sir, the block of thorium is ready.
After making a carbide in the electric furnace it was found possible to decompose it by further increasing the heat to a point where the second element is volatilized and the pure carbon in the form of artificial graphite remains. In more recent work the carbide containing the silicon has been done away with and ordinary anthracite coal used as a charge from which the pure graphite is obtained.
In like manner silicon-eisen, containing 9 per cent. of silicon, was treated, but not giving so satisfactory a result. A small quantity only of silicon separates in the uncombined form, the greater quantity separating in the form of silica, SiO , the amorphous silicon so obtained apparently being more prone to oxidation than the boron so obtained.
Acheson, of Pittsburg, while so engaged, and in obtaining graphite from coal by the heat of an electric furnace, discovered that combination of silicon and carbon now known as carborundum, which has commercial value as an abrasive." "I know about that," bowed Nick.
The material best adapted for this purpose is electric light carbon, as it possesses the necessary amount of electrical resistance, and is capable of enduring any known degree of heat when protected from oxygen without disintegrating or fusing; but crystalline silicon or other equivalent of carbon can be employed for the same purpose.
