Carbon Dioxide (5N)

Carbon dioxide is a colorless, odorless, tasteless and non-toxic gas. Melting point -56.6°C (0.52MPa), boiling point -78.6°C (sublimation), density 1.977g/L.

Carbon dioxide has a wide range of industrial uses.

Dry ice can be obtained by liquefying carbon dioxide into a colorless liquid under a certain pressure, and then rapidly solidifying under low pressure. Its temperature is minus 78.5 ℃. Because of its very low temperature, dry ice is often used to keep objects frozen or cryogenic.

Disilane

Disilane (chemical formula: Si₂H₆) is a non-corrosive toxic gas. It is pyrophoric in air, with an ignition point below room temperature. Upon exposure to air, it ignites instantly and decomposes into silane (SiH₄) and hydrogen (H₂). Under its own vapor pressure, disilane exists as a liquid. It can be mixed in any proportion with hydrogen, argon, nitrogen, and helium.

Its boiling point is -14.3 °C, melting point is -132.6 °C, and critical temperature is 150.85 °C. Disilane has a wide flammability range: at concentrations above 0.2%, it burns with a visible flame; at concentrations below 0.2%, it undergoes oxidation, producing white SiO₂.

Disilane exhibits chemical properties similar to silane, but with higher reactivity. It is less stable than silane, decomposing slowly into silane and hydrogen at room temperature. At 300–500 °C, it decomposes into SiH₄, SinHm, and H₂, and also decomposes under light exposure.

Disilane is mainly used in applications such as solar cells, photoconductive drums, amorphous silicon films, epitaxial growth, oxide films, nitride films, and chemical vapor deposition (CVD).

Hexachlorodisilane

Hexachlorodisilane, also known as hexachlorodisilane or disilicon hexachloride, is a colorless liquid with high stability and low volatility. It reacts violently upon contact with water and is insoluble in alcohols and strong alkalis.

As a member of the chlorosilane family, HCDS represents one of the high-value oligomeric chlorosilanes. It serves as an important intermediate in organic synthesis and is widely utilized for the preparation of disilanes and related compounds.

Beyond its role in chemical synthesis, HCDS is increasingly applied in thin film manufacturing, semiconductor processes, and the solar energy industry, making it a critical material in advanced electronic and energy applications.

Hydrogen Bromide (5N)

Hydrogen bromide is an inorganic compound with a chemical formula of HBr and a molecular weight of 80.91. It is a colorless gas with standard conditions and is the basic raw material for chemical synthesis.

Nitrous Oxide (5.5N)

Depending on its purity, nitrous oxide (often called “laughing gas”) is widely used in the food, medical, and semiconductor industries.

Jinhong Gas has greatly improved the purity and production capacity of nitrous oxide through continuous technological updates, and is one of the outstanding suppliers in the semiconductor field.

Nitrous oxide may be used as an aerosol propellant in various fields:

-for whipped cream (because it improves the foaming characteristics of the cream), syrups, concentrates of coffee, chocolate and various flavours, sauces for grilled meats, vinaigrette etc. -pharmaceutical field

-cosmetics (perfumes, eau de cologne, hair spray, etc.)

-household products, paints and varnishes, insecticides

-aerosols for use at low temperature, such as de-icers, engine starting boosters, etc.

Sulphur Dioxide

Sulfur dioxide is a colorless gas at room temperature with a pungent odor. It has strong permeability, can penetrate into various gaps quickly, and is easily absorbed by items, especially wet items. Sulfur dioxide is toxic to humans, and the maximum allowable concentration in the air is 15mg/m3.

Titanium tetrachloride

Depending on its purity, titanium tetrachloride (TiCl₄) is widely used in the chemical, materials, and semiconductor industries.

Through continuous technological upgrades, Jinhong Gas has independently developed high-purity and electronic-grade titanium tetrachloride, providing customers with clean and stable products.

Triethyl borate

Triethyl borate, depending on its purity, is widely used in semiconductor manufacturing, lithium-ion battery additives, flame-retardant materials, green synthetic chemistry, and specialty coatings.

Triethyl phosphate

Depending on its purity, triethyl phosphate (TEP) is widely used in semiconductors, polyurethane flame retardants, green solvents, heat-resistant coatings, and other fields.

Jinhong Gas has continuously upgraded its production technology, significantly improving both the purity and output of triethyl phosphate, becoming a leading supplier in the semiconductor industry.

Trimethylsilylamine

Trimethylsilylamine (chemical formula N(SiH₃)₃, abbreviated as TSA) is a colorless liquid with good fluidity and high sensitivity to moisture. It has a melting point of -105.6 °C and a boiling point of 52 °C. TSA is an important silicon-containing compound with specific applications in the semiconductor industry, where it is used to deposit high-purity silicon oxide films as gap-fill materials in semiconductor processes. In addition, it can also serve as a precursor for synthesizing other organosilicon compounds or aminosilanes.

Y-Cylinder/T-Cylinder

Y-Cylinders or T-Cylinders are available if you want. Compared with gas cylinders, Y-cylinders or T-cylinders have more gas volume, longer use time, and fewer replacements, which not only improves work safety, but also reduces unnecessary labor costs.
