Zirconium is a silver -white shiny metal. It is passivated very quickly through an oxide layer and is therefore corrosion -resistant. Zirconium has a high melting point, can be flammable in powdered form and burns with a magnesium -like flame. Zirconium is non -toxic and occurs in a small amount in the human body. Zirconium band is relatively soft, so it can be rolled and forged well. This metal can also be processed in a chip, but it should be ensured that fine chips and dust can be flammable. Circonium does not burn when compact. Because zirconium produces a light light without fog formation in the combustion process, it is used to produce flash light powder as well as fireworks and signal lights. In nuclear technology, it is used thanks to its permeability to neutrons and accordingly in.
