Product Introduction

Products Description

Silicon metal is mainly composed of silicon, so it has similar properties to silicon. Silicon has two allotropes: amorphous silicon and crystalline silicon. Amorphous silicon is a gray-black powder and is actually a microcrystal. Crystalline silicon has the crystal structure and semiconductor properties of diamond, melting point 1410℃, boiling point 2355℃, Mohs hardness 7, brittle.

Amorphous silicification is active and can burn violently in oxygen. It reacts with halogens, nitrogen, carbon and other non-metals at high temperatures, and can also interact with magnesium, calcium, iron and other metals to generate silicides, amorphous silicon is almost insoluble in all inorganic and organic acids including hydrofluoric acid, but can dissolve in the mixed acid of nitric acid and hydrofluoric acid, concentrated sodium hydroxide solution can dissolve amorphous silicon and release hydrogen. Crystalline silicon is relatively inactive, even at high temperatures do not combine with oxygen, it is not soluble in any inorganic and organic acids, but soluble in nitric acid and hydrofluoric acid mixed acid and concentrated sodium hydroxide solution.
