silicon fluoride - Introduction
The silicon fluoride refers to a compound containing a fluorine atom and a silicon atom. Its chemical formula is SiF4. The following is a description of the nature, use, preparation and safety information of silicon fluoride:
Nature:
1. silicon fluoride is a colorless gas, soluble in water at room temperature;
2. has a pungent smell, has a strong corrosive, can corrode glass and other materials;
3. has a high boiling point and melting point, not easy to burn;
4. with many metal reaction, can generate the corresponding metal fluoride.
Use:
1. silicon fluoride used as a variety of chemical raw materials, such as the synthesis of high purity silicon, electronic components manufacturing;
2. Used as a cleaning agent and etchant, commonly used in the semiconductor industry to remove impurities and etch the surface of silicon wafers;
3. in the preparation of other fluorine-containing organic synthetic materials, as a fluorinating agent.
Method:
The preparation of silicon fluoride usually has the following methods:
1. silicon and fluorine gas reaction: silicon and fluorine gas reaction to obtain silicon fluoride;
Si 2F2 → SiF4;
2. reaction of silicate with hydrofluoric acid: reacting silicate with hydrofluoric acid to obtain silicon fluoride;
SiO2 4HF → SiF4 2H2O.
Safety Information:
1. silicon fluoride is strongly corrosive, avoid direct contact with skin and eyes;
2. use the need to wear protective clothing, protective glasses and gloves and other personal protective equipment;
3. should be used in a well-ventilated place, to avoid inhalation of silicon fluoride gas;
4. silicon fluoride is a highly harmful substance, and its discharge and treatment should be strictly controlled.
