Physical and chemical properties.The four known crystalline modifications of carbon are graphite, diamond, artificial graphite, and lonsdaleite. Graphite is a gray-black, opaque, scaly, very soft substance that has a metallic luster and is greasy to the touch. It consists of hexagonal crystals, wi...
As if by a flash of lightning I awoke; and this time also I spent the rest of the night in working out the rest of the hypothesis. Let us learn to dream, gentlemen, then perhaps we shall find the truth... But let us beware of publishing our dreams till they have been tested by ...

electrode,terminal through which electric current passes between metallic and nonmetallic parts of an electric circuit. In most familiar circuits current is carried by metallic conductors, but in some circuits the current passes for some distance through a nonmetallic conductor. For example, inelectrolysi...

[161]. Urban copper mining from secondary resources may employ pyrometallurgy and hydrometallurgy techniques to reduce and extract copper. Black copper smelting uses pyrometallurgy to reduce and oxidize liquid copper-containing materials at high temperatures. Coke/coal is a popular fuel and reductant ...
The interaction of a magnesia-carbon refractory with iron under flash ironmaking conditions has been investigated in this work. Oxidation of carbon from the magnesia-carbon refractory took place and the formation of magnesiowustite (MgxFe1-xO) solid solution occurred as a result of the interaction ...
