The effect of silicon

Weden Metal Co.,Limited | Updated: Jan 08, 2018

Silicon is present in nature with a large amount of silicate and quartz deposits.If carbon is the main element of the biological world, then silicon is the main element that makes up the mineral world on earth.

Silicon is 27.7% abundance in the earth's crust, ranking second among all elements, and the most abundant element in the earth's crust is SiO2, which is formed by the combination of oxygen and silicon, accounting for 87% of the total mass of the earth's crust.

The earth, stone and sand at our feet, the bricks we use, the tiles, the cement, the glass, the ceramic, and so on, these things that we often encounter in our daily lives, are the compounds of silicon.Silicon, it's really all over the world, it's the element of it.

Is the difference between monocrystalline silicon and polycrystalline silicon, in the coagulation of molten elemental silicon, silicon atoms arranged in diamond lattice into many crystal nucleus, if the crystal nucleus grow into the same grain size, crystal orientation of single crystal silicon is formed.If these crystals grow to different grains of grain, polysilicon is formed.

Silicon has crystalline and amorphous forms.Crystalline silicon is divided into monocrystalline silicon and polycrystalline silicon, they all have the diamond lattice, crystal hard and brittle, with metallic luster, can conduct electricity, but lags behind metals, electrical conductivity and increases with temperature rise, is in the nature of semiconductor.The melting point of crystalline silicon is 1410C, boiling point 2355C, and the amorphous silicon is a black grey powder.
