(A) Hydrogen is produced by electrolysis of water or from water gas, coke gas or hydrocarbons. Hydrogen is generally regarded as a non-metal. It is stored under pressure in steel cylinders. It is used for hydrogenation of oils (producing solid fats), for cracking of petroleum products, in the synthesis of ammonia, for cutting or welding metals (oxygen-hydrogen soldering lamps), etc. This heading does not include deuterium (stable and nitrogen) of heading 2845 and tritium (radioactive isotope of hydrogen) of heading 2844.

The term “rare gases” (inert gases) refers to the elements listed below. They are distinguished by their chemical inertia and electrical properties, in particular, the ability to emit colored rays (used, for example, in neon advertising) under the influence of high voltage discharges. (1) Helium (a non-flammable gas used, for example, for inflating into air balloons). (2) Neon (produces pink-orange-yellow light or (in combination with mercury vapor) "daylight"). (3) Argon (colorless, odorless gas used to produce an inert atmosphere in bulbs of electric lamps). (4) Krypton (used in the same way as argon or to produce pale purple light). (5) Xenon (produces blue light). Inert gases are obtained by fractionation of liquid air and (in the case of helium) from certain natural gases. They're stored under pressure. Radon is a radioactive and nertic gas of heading 2844 and is formed by radioactive decay of radium. (B) OTHER NEMETALS This heading covers other non-metals: (1) Nitrogen. Nitrogen is a gas that extinguishes a flame because it does not burn or support combustion. It is obtained by fractional distillation of liquid air, stored under pressure in steel cylinders. Nitrogen is used mainly for the production of ammonia and calcium cyanamide, as well as to create an inert atmosphere in the bulbs of electric lamps, etc. (2) Oxygen. This is a g az that supports combustion, obtained mainly by fractional distillation of liquid air. Stored under pressure in steel cylinders or sometimes in the form of a liquid - in vessels with double walls. Compressed oxygen is used in oxygen-hydrogen and acid native acetylene solder lamps for welding (autogenic welding) or for cutting metals such as iron. It is also used in metallurgy of ferrous metals and in medicine (inhalation). This heading also includes ozone, which is an allotropic form of oxygen formed by the action of electrical sparks or discharges on oxygen. It is used for disinfection of water (ozonation), for oxidation of drying oils, for bleaching cotton, as an antiseptic and for medicinal purposes. (3) Bohr. Boron is a hard substance of chestnut color, usually a powdered form. It is used in metallurgy and for the manufacture of heat regulators and thermometers with high sensitivity.

Due to the very high absorption rate of slow neutrons, boron is also used in pure form or in an alloy with steel to make lightweight control rods for nuclear reactors. (4) Tellur. Solid (specific gravity 6.2) substance in amorphous or crystalline form. It is relatively good for heat and electricity and has some metallic properties. It is used in some alloys (for example, telluro-lead alloys), as well as as a vulcanizing agent. (5) Silicon. Silicon is obtained almost exclusively by carbonthermal reduction of silicon dioxide using electric arc furnaces. It is a poor conductor of heat and electricity, harder than glass, usually has the appearance of powder or more often shapeless pieces of chestnut color. It crystallizes as gray needles with a metallic luster. Silicon is one of the most important materials used in electronics. Very pure silicon, obtained, for example, by growing crystals, can have an untreated elongated shape of cylinders or rods; when alloyed and boron, phosphorus, etc. is used for the production of, for example, diodes, transistors and other semiconductor devices, as well as solar cells. Silicon is also used in metallurgy (for example, in iron-based or aluminum alloys) and in chemistry for the preparation of silicon compounds (for example, silicon tetrachloride). (6) Phosphorus. Phosphorus is a solid, soft and plastic in consistency, obtained by processing natural phosphates mixed with sand and carbon in an electric furnace. There are two main types of phosphorus: (a) "white" phosphorus, transparent and yellowish, toxic, flammable, dangerous in circulation. It comes in the form of molded rods in water-filled containers of black stack, ceramics or most commonly metal; these containers should not be left in the cold; (b) red phosphorus, known as "amorphous", but which can practically crystallize, is an opaque solid, non-toxic, non-phosphorescent, denser and less active than "white" phosphorus. Red phosphorus is used in the production of matches, in pyrotechnics and as a catalyst (for example, in the chlorination of acyclic acids). Some medicines contain phosphorus (for example, phos forated fish oil). It is also used to kill rats or to produce phosphoric acids, phosphates (pituphosphites), calcium phosphide, etc. (7) Arsenic. Arsenic (unrefined arsenic) is a solid substance extracted from natural arsenopyrites. It exists in two main forms:

(a) ordinary, so-called “metallic” arsenic, in the form of shiny crystals of steel color, brittle, insoluble in water; (b) yellow arsenic, crystalline, rather unstable. Arsenic is used in the production of arsenic disulfide, large fraction, hard bronze and various other alloys (tin, copper, etc.). (8) Selen. Selenium, quite similar to sulfur, exists in several varieties: (a) amorphous selenium in the form of reddish flakes (selenium); (b) vitreous selenium, a poor conductor of heat and electricity. It has a shiny fracture of brown or reddish color; (c) crystalline selenium, in the form of gray or red crystals. A relatively good conductor of heat and electricity, especially in the light. It is used in the production of photovoltaic cells and in doping with other elements - in the production of semiconductor devices, in photography, in powdered form (red selenium) is used for the production of rubber, special lenses, etc. This heading does not cover selenium in the form of a colloidal suspension (used in medicine) (Chapter 30). Antimony is classified as metal in the Nomenclature (heading 8110). Some of the non-metals of this group (e.g., silicon and selenium) may be doped with elements such as boron, phosphorus, etc. in a ratio of about 1 part per million for use in electronics. They are classified in this heading provided that they are in rough shapes, such as elongated or in the form of cylinders and rods. Cut in discs, plates or similar shapes, they fall in heading 3818.
