Did you know that in Greece, in only two areas (in Northern Evia and in the area of ​​Gerakini near Thessaloniki) there is a rock that looks like snow and is pure "gold" for the economy and industry?
We fly over North Evia, to a mountain that resembles fresh snow but is… white stone.
White stone or magnesite is white, relatively soft, absorbent and chemically inert. It is used as a raw material for the production of magnesium.
Magnesium is a metal used in the manufacture of light alloys for aircraft fuselages, jet engine components, missiles and missiles, cameras and optical instruments. As magnesium burns with a surprisingly bright white light, it is used in fireworks and other forms of pyrotechnics, such as flares.
In industries such as:
In the steel industry, in the industry of sulfuric acid, sugar, fertilizers, glass, pharmaceuticals and pesticides. As a filler in the production of paints, paper, plastics and tires.
In the production of refractory materials and special refractories such as:
Chromium-magnesiums with the addition of refractory chromite (Cr2O3 + Al2O3 57% and Cr2O3 30%). These refractories are widely used in the lining of interior surfaces of ovens.
In metallurgy, especially in the production of industrial alloys:
Electronic metals with 90% Mg and 10% Al, Zn, Mn and other elements
Magnolia with 10-30% Al and 90-70% Mg
Duralumin with 0.5-2% Mg and the rest Al and a little Si
In the neutralization or retention of pollutants
Caustic magnesium is used as a raw material for the manufacture of refractories. It is also used in the chemical industry, as a chemical accelerator, in the manufacture of tires, in piping, in agriculture as a soil improver, in the production of animal feed and fertilizers, in the pharmaceutical and cosmetics industries and as a fire retardant in cables and electrical appliances. At the same time, it has many applications in environmental technology, such as in the removal of heavy metals, in the management - inactivation of industrial waste and acid effluents, in the stabilization of solid waste and in the treatment of contaminated soils with heavy metals.
Bipolar magnesia is considered to be highly refractory and is mainly used in the manufacture of refractory bricks. It is also used as an insulating material for tubular resistors, in magnesium phosphate cements and in cable insulation.
