Silver liquid mercury 99.999% Mercury is a metal that at room temperature has the appearance of a silvery-white liquid. Mercury is classified as a low-activity metal, the metal dissolves in nitric acid and aqua regia, and is stable in acid solutions that do not have oxidizing properties.   Mercury is present in almost all sulfide minerals. Of industrial interest is cinnabar (mercuric sulfite), from which the metal is extracted. Mercury is obtained by a metallothermic method or by roasting mercury sulfide, in which metal vapors are condensed and collected.   Mercury and its compounds are widely used in such sectors of the national economy as medicine, technology, metallurgy, the chemical industry and agriculture. In medicine, mercury is a preservative for vaccines. It is used in medical thermometers and serves to measure body temperature. The metal is used in radiopharmacology and dentistry.   In technology, the metal is used as a working fluid for mercury thermometers. Thallium-mercury alloy is used in measuring devices designed to measure low temperatures. Fluorescent lamps are filled with mercury vapor to obtain sources of hard ultraviolet light. The metal itself and its alloys are used for sealed switches and position sensors. The metal is part of some current sources (chemical), the most well-known is the mercury-zinc source. Mercury serves as a working fluid for heavily loaded hydrodynamic bearings. An alloy of mercury with cesium also acts as a working fluid in ion engines.   In metallurgy, mercury is used to produce alloys. The metal plays the role of a cathode in the electrolytic production of alkalis, chlorine and many active metals. Mercury is used to process gold-bearing clays to obtain gold from them. The metal is used in the processing of secondary aluminum.   In the chemical industry, mercury is used to quantitatively determine ammonia and as a catalyst in the industrial production of acetylene and acetaldehyde. In agriculture, mercury compounds are used as pesticides and for grain dressing.

Liquid mercury is used in barometers manometers due to its high density. Hg is also a way to measure pressure in millimeters of mercury. It is still sometimes used in electrical switches as a liquid contact. 2. It is also used in thermometers because it has a large thermal expansion constant over a large temperature range although it is phased out in favor of safer liquids. 3.

Product (Luna-M)/SGM, Hg2Sb2O7, density from 17.3-20 grams/cm3, weight 1730 grams, color - silvery-matte with a cherry tint. Net weight: 1960 grams.   Mercury oxystibate - pyroantimonate (formula Hg2Sb2O7).   Production Natural pyroantimonate has a rather low quality, so it is produced artificially for industry.   HgO+=Hg2Sb2O7+H2O   Then the pyroantimonate solution is freed from water.   The first patent for the production of pyroantimonate was obtained by the company .   Application In small quantities it is used as a semiconductor material, sometimes used in various exchange and substitution reactions.   Biological role Very poisonous, in case of poisoning it combines the toxicological properties of its components, mercury and antimony.   Price for 1 jar: 487 935 UAH.

Physical properties Single-crystal selenium (99.9999%)   Solid selenium has several allotropic modifications:   Grey selenium (γ-Se, "metallic selenium") is the most stable modification with a hexagonal crystal lattice; Red crystalline selenium - three monoclinic modifications: orange-red α-Se, dark red β-Se, red γ-Se; Red amorphous selenium; Black glassy selenium. When gray selenium is heated, it produces a gray melt, and with further heating it evaporates with the formation of brown vapors. When the vapors are cooled sharply, selenium condenses as a red allotropic modification.   Chemical properties Selenium is an analogue of sulfur and exhibits oxidation states of −2 (H2Se), +4 (SeO2) and +6 (H2SeO4). However, unlike sulfur, selenium compounds in the oxidation state +6 are very strong oxidizers, and selenium compounds (−2) are much stronger reducing agents than the corresponding sulfur compounds.   The simple substance selenium is much less chemically active than sulfur. Thus, unlike sulfur, selenium is not capable of burning in air on its own. Selenium can only be oxidized with additional heating, during which it slowly burns with a blue flame, turning into dioxide SeO2. Selenium reacts with alkali metals (very violently) only when melted   Unlike SO2, SeO2 is not a gas, but a crystalline substance that is highly soluble in water. Obtaining selenious acid (SeO2 + H2O → H2SeO3) is no more difficult than sulfurous acid. And by acting on it with a strong oxidizer (for example, HClO3), we obtain selenic acid H2SeO4, which is almost as strong as sulfuric acid.
