What is Molybdenum carbide

Submitted by admin on Thu, 12/06/2018 - 09:48

Molybdenum carbide (Mo 2 C) is a hexagonal network, aswell centered cubic filigree face. It shows a top melting point and top hardness, acceptable thermal adherence and automated strength, accomplished bane resistance.Molybdenum carbide usually as a blanket actual with top hardness, chafe attrition is acclimated and high-temperature backbone properties. Molybdenum may be added to the cermet, in adjustment to advance its achievement and aswell generally acclimated in the bigger appearance alloy.

Development of metal powder injection process

The prospect of chromium compounds

Submitted by admin on Thu, 12/06/2018 - 09:32

Organic compounds are commonly used to the material in the modern industry, is an important part in industrial production, the chromium oxide is a kind of compound, it is a light green to dark green small six square crystal. When it's hot, it turns brown. Crystal extrahard. Very stable, even in the heat of the hydrogen flow under no change. Potassium bromate solution in heating, slightly soluble in acid and alkali, almost insoluble in water, ethanol and acetone. And irritation.

What is the Chromium

Submitted by admin on Wed, 12/05/2018 - 09:49

Chromium, chemical symbol Cr, elemental metal for the steel gray. Element's name comes from the Greek, meaning "color", because chromium compounds have colors. In 1797 the French chemist walker orchid (L.N.V auquelin) in the Siberian red lead chromium (lead) find a new mineral, the next year with carbon reduction. Chromium content in the earth's crust is 0.01%, the highest in 17th. 

The development prospects of silicon metal

Submitted by admin on Wed, 12/05/2018 - 09:45

Silicon is one of the half metal, old name "si". Melting point is 1420 ℃, the density of 2.34 grams per cubic centimeter. Qualitative hard and brittle. At room temperature does not dissolve in acid, soluble in alkali. The nature of the metal silicon and germanium, lead, tin, is in the nature of semiconductor. Silicon in the earth's crust is of rich resources, second only to oxygen, accounting for more than a quarter of the total weight of the earth's crust, in the form of silica or silicate.
