Application of Cannon Packing in Special Electronic Gas Industry

Application of Cannon Packing in Special Electronic Gas Industry


The electronics industry is an indispensable industry driver for the development of high-tech industries in today's technological era. Because of the many types of gases required and the high-quality requirements, we usually refer to the gases used in the electronics industry as special electronic gases in order to distinguish them from other gas chemical fields.

The main special electronic gases are trifluoromethane, sulfur fluoride, nitrogen trifluoride, boron trichloride, etc.


Trifluoromethane (CHF3), also known as fluoroform, is an organic compound gas, which is colourless and odourless at room temperature, soluble in water, ethanol and acetone, with a melting point of -160°C and a boiling point of -84°C. It is mainly used as a raw material for fire extinguishers and low-temperature refrigeration.  


Sulfur fluoride (SF6), a stable gas of inorganic compounds, colorless and non-combustible at room temperature, odourless and non-toxic, slightly soluble in water, ethanol and ether, density is about 6.0886kg/m3, melting point is -50.8℃, boiling point is -63.8℃ (sublimation), the critical temperature is 45.6℃, critical pressure is 3.76MPa, accounting for a large role in the smelting and casting process of non-ferrous metals. It can also be used for gas insulation of electronic and electrical equipment, etc.


Nitrogen trifluoride (NF3), also an inorganic compound gas, is colorless at room temperature, and insoluble in water, with a melting point of -207°C and a boiling point of 129°C. It can be used as a high-energy fuel and plasma etching gas in the microelectronics industry.


Boron trichloride (BCI3), alias boron chloride, a colorless fuming liquid or gas, belongs to the dangerous chemicals, can be soluble with benzene, carbon disulfide, melting point is -107.3 ℃, the boiling point is 12.5 ℃, is a doping source of semiconductor silicon, but also organic synthesis catalyst, etc. Boron trichloride is harmful to humans, can not be inhaled, orally or through the absorption of the skin, the environment is also a certain danger.


Naike Chemical specializes in the production of laboratory distillation packing such as laboratory packing, cannon packing, theta(θ) ring packing, etc. The cannon packing is especially suitable for the production of special electronic gases and the manufacture of high purity special electronic gases.It can be said that cannon packing achieves a double balance of high purity and high yield in the high purity distillation industry.


Cannon Packing, a super-efficient packing for laboratory, has a wide market in foreign countries. As the application of industrial gases in high-tech industries deepens, cannon packing for the production of special electronic gases in the domestic market will also usher in a promising future.
