LPW have launches new powder flow measurement kit

Submitted by admin on Fri, 12/07/2018 - 07:50

AM powder metal specialist LPW Technology has developed Powderflow, a comprehensive powder flow measurement kit that allows users to characterize the powder flow to known ASTM standards.

According to the company, some users can confuse machine problems with powder problems and vice versa, resulting in significant time and cost being wasted before a fault is found.

Applications of Chromium(III) oxide

Submitted by admin on Fri, 12/07/2018 - 07:46

Chromium(III) oxide is an inorganic compound. It is one of principal oxides of chromium and is used as a pigment. In nature, it occurs as the rare mineral eskolaite.

Because of its considerable stability, chromia is a commonly used pigment and was originally called viridian. It is used in paints, inks, and glasses. It is the colourant in "chrome green" and "institutional green." Chromium(III) oxide is a precursor to the magnetic pigment chromium dioxide, according to the following reaction:

History of Metal silicon

Attention was aboriginal declared by Antoine Lavoisier to the silica oxide as accessible a basal actinic aspect fatigued to abstract in 1787. After an attack to silicon in 1808, Sir Humphry Davy called "silicon" proposed for silicon, the Latin silica Silicis for Flint, and abacus the "-ium" ends, because he believed that it is a metal was.

What is Molybdenum carbide

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.
