The escapement is the regulating organ of the watch, and at the heart of this new creation, the constant escapement is a blade of silicium, finer than a human hair. ❋ Unknown (2008)
So long before being forwarded to Tampa Town, the iron ore, molten in the great furnaces of Coldspring, and brought into contact with coal and silicium heated to a high temperature, was carburized and transformed into cast iron. ❋ Unknown (2003)
While the large presence of silicium and aluminum-compounds improves the quality of slate, its quality is impaired by the presence of lime, pyrites and carbon in higher quantities. ❋ Unknown (1996)
In this case, decomposition proceeds in a continuous manner; we obtain at the negative pole hydrogen, and at the positive pole a regular disengagement of a colorless gas in which crystallized silicium in the cold burns with great brilliancy, becoming fluoride of silicium. ❋ Various (N/A)
On remelting of cast iron, increase in tensile strength was observed, which attained its maximum in iron with a small percentage of silicium after the third, and in such with a large amount after the fourth melting. ❋ Various (N/A)
Experiments in regard to the relation between chemical composition and strength of the material have established that a large amount of silicium, graphite, manganese, and combined carbon reduce the elasticity, strength, and tenacity of cast iron, and that a limited percentage of silicium counteracts the injurious influence produced by an excess of combined carbon. ❋ Various (N/A)
If the hydrofluoric acid contains a small quantity of water, either by accident or design, there is always disengaged at the positive pole ozone, which has no action on crystallized silicium. ❋ Various (N/A)
The two elements to be avoided by the founder are silicium and sulphur. ❋ Various (N/A)
In view of the fact that samples of cast iron with equal percentage of silicium and carbon yield on casting a different product, it has become necessary to institute experiments as to the cause of this behavior. ❋ Various (N/A)
During these processes of fusing, the amount of silicium, carbon, and manganese had been gradually decreased, and amounted to 12.7, 17.6, and 24.4 per centum for silicium in the three samples examined. ❋ Various (N/A)
To him also is due the isolation of the elements yttrium, beryllium, and titanium, the observation that silicium can be obtained in crystals, and that some meteoric stones contain organic matter. ❋ Various (N/A)
Cast iron free of silicium yields on cooling the entire amount of carbon in the amorphous state, while presence of the former metal gives rise to the formation of graphite, and, consequently, causes a partial separation of carbon. ❋ Various (N/A)
A fifth melting of the cast iron renders it hard, brittle, and white, through oxidation of silicium and subsequent lowering of the amount of carbon. ❋ Various (N/A)
Wöhler and Sainte Claire Deville discovered the crystalline form of boron, and Wöhler and Buff the hydrogen compounds of silicium and a lower oxide of the same element. ❋ Various (N/A)
Fusing with silicium would give a gold-silicide that might fill the bill for hardness; but I can't even make a guess as to how they do the tempering. ❋ Thomas Allibone Janvier (N/A)
My own experience leads me to think that a cast iron having about 3 per cent. of carbon, a small per centage of phosphorus, say about ½ of 1 per cent., and very small quantities of silicium, the less the better, and traces of manganese ❋ Various (N/A)
It also was observed that the more manganese the iron contains the less readily the percentage of silicium is diminished; and since manganese is more subject to oxidation than silicium, it is capable to reduce silicic acid of the slag or lining to metal, and thus to augment the amount of silicium in cast iron. ❋ Various (N/A)
From trials conducted by Ledebur, it appears that cast iron is rendered suitable for foundry purposes -- i.e., to fill the moulds well and to yield sharp and definite forms free of flaws, to be cut with a chisel, and turned on a lathe -- through a certain percentage of graphite, whose presence depends on that of carbon and silicium. ❋ Various (N/A)
United by a rivalry which would have divided less noble minds, these two great chemists carried on together their researches in chemistry, and joined their forces to clear up points still obscure in the history of boron, silicium, and the metals of the platinum group, and remained closely united, which each year only strengthened. ❋ Various (N/A)
The increase in tensile strength was accompanied by a loss of silicium, graphite, and manganese coupled with a simultaneous augmentation of combined carbon. ❋ Various (N/A)
