The reaction between fluorine and silicon is one of the most beautiful of all these extraordinary manifestations of chemical activity.
As crystalline silicon only melts at a temperature superior to 1,200°, the heat evolved must be very great.
Silicon dioxide, one of the most inert of substances at the ordinary temperature, takes fire in the cold in contact with fluorine, becoming instantly white-hot, and rapidly disappearing in the form of silicon tetrafluoride.

Whistler later said: 'Had silicon been a gas, I would have been a major-general.
The hot flame mixed with air beating down upon the melted iron on hearth b for two hours or so, burns out the silicon and carbon, the process being facilitated by stirring and working the mass with tools.
The red hot cast iron contains more or less carbon and silicon, and the air uniting with the carbon and silicon burns it out, and in doing so furnishes the heat for the continuance of the operation.
The cells that carry on the silicon metabolism in me are not human.
I should have remembered from your famous papers, The Need Of Trace Silicon In Human Diet and Silicon Deficiency Diseases.
To determine the safe limits of silicon consumption and if there are any dangers in an overdose.
Of course, the great change over into silicon catalysis would be a shock and require adjustment and, of course, the change must be made in several easy stages--and those who could not adjust would die.
I'm turning intosilicon plastic myself, he thought.
A detector that uses a crystal of silicon for its sensitive element.
Carborundum is a crystalline silicon carbide formed in the electric furnace.
Galena is the crystal that is generally used, for, while it is not quite as sensitive as silicon and iron pyrites, it is easier to obtain a sensitive piece.
His notes include the use of powdered silicon mixed with lime or other very infusible non-conductors or semi-conductors.
He also placed some of these refractory metals directly in the circuit, bringing them to incandescence, and used silicon in powdered form in glass tubes placed in the electric circuit.
The same components, differently ordered, can appear to us as graphite or diamonds, sand or siliconfor chips.
A mixture of silicon (or of the ferro-silicon alloy containing 90 per cent.
It is a silvery-white close-grained iron, very hard and rather brittle, somewhat like cast iron but with silicon as the main additional ingredient in place of carbon.
When this comes in contact with moist air it gives off thick, white fumes, for water decomposes it, giving a white powder (silicon hydroxide) and hydrochloric acid.
Since silicon has been robbed with difficulty of its oxygen it takes it on again with great avidity.
