Density and specific heat of zirconium and zirconium alloys
Are you interested in the physical and mechanical properties of zirconium and its alloys from the supplier AvecGlob? Here you will find interesting information on this topic.
Application of zirconium
Zirconium — very durable, malleable, malleable, shiny silver-gray metal. Its chemical and physical properties are similar to the chemical and physical properties of titanium. Zirconium is extremely resistant to heat and corrosion. Zirconium is lighter than steel, and its hardness is similar to copper. When grinding, the metal can spontaneously ignite in the air, especially at high temperatures. Zirconium powder is black and is considered a material that has an extremely high fire hazard. Zirconium does not dissolve in acids and alkalis.
The most famous and widely used zirconium-based alloy is zircalloy. It is used in nuclear applications because it can not easily absorb neutrons. Tsirkalloy is also used in catalytic converters, percussion caps and in the composition of furnace bricks of heating equipment. Baddeleyite (zirconium with significant impurities) is used in laboratory crucibles.
The main end uses of the zircon mineral (ZrSiO 4) are refractories, ceramic opacities and foundry sands. Zircon is used in jewelry and dental practice. Metal also has many other uses, including photographic light bulbs and surgical instruments, television glasses, electronic vacuum tubes, and also as hardener for some steels. Zirconium alloys are an integral part of surface coatings, because they have excellent water resistance and strength.

Technological features — zirconium should be handled with care, as zirconium powder and chips are easily ignited. Zirconium is plastic and easily processed. However, to prevent the grinding of waste, proper lubrication must be used. For welding zirconium, the best method is a gas welding with a tungsten arc. For zirconia welding, adequate protection is required, which otherwise can lead to the formation of weak and brittle welds.
