Borax. Also known as sodium borate, moonstone powder.
English name: borax; sodiumtetraborate;sodiumborate
Molecular formula Na2B4O7·10H2O
Molecular weight traits: borax five-color translucent crystal or white crystalline powder. Odorless, salty taste. Specific gravity.
Eight molecules of crystalline water are lost at 60 and all of them at 320, weathering in the air. Anhydrous matter (Na2B4O7) has a melting point of 741 and a boiling point of 1575. Decompose at the same time.
Slightly soluble in cold water, more soluble in hot water, slightly soluble in ethanol. The aqueous solution is alkaline. When melted, it is a colorless, glassy substance.
** : Mainly using carbon-alkali process: the pretreated boron-magnesium ore powder is mixed with sodium carbonate solution and heated, and then reacted by carbon dioxide pressurization. The pressurized alkaline hydrolysis process is prepared by the thermal decomposition of boron-magnesia powder with sodium hydroxide solution, and can also be directly produced from natural borax ore.
Specifications GB 537—84.
Appearance: Small white crystals.
Packing: Packed in plastic woven bags lined with plastic film bags, net weight 50 kg per bag. Inside the bag, a quality certificate should be attached. The packaging bag should be coated with a firm logo, including: the name of the manufacturer, the name of the product, the gross net weight, the batch number and the trademark.
Uses: Borax is used in industry, glass, enamel and other industries and in agriculture as a trace element fertilizer.

Borax is a very important boron-containing mineral and boron compound, usually a white powder containing colorless crystals that is easily soluble in water. Borax has a wide range of uses, from cleaning agents, cosmetics, pesticides, to buffer solutions and other boron compounds.
Boron is an essential growth element for the human body, animals and plants (especially beans, vegetables, and fruits), and mainly exists in three forms: boric acid, borax and its complexes formed with sodium, magnesium and calcium.
The chemical composition of borax is sodium tetraborate, which exists in the form of boric acid under acidic conditions. Trace amounts of boron are beneficial to the human body, such as preventing osteoporosis and promoting the metabolism of calcium in the human body.
After borax is consumed, the substance is converted into boric acid by gastric acid, which is absorbed by the gastrointestinal tract. Although the amount is not high at a time, it is slowly excreted, which accumulates and eventually accumulates in the body and becomes poisoned.
Borax is toxic to a variety of organs of the human body, harms the action of digestive tract enzymes, reduces appetite, inhibits the absorption of various nutrients, thereby accelerating the decomposition of fat, weight loss, acute vomiting, diarrhea, dizziness, headache and other symptoms, and even erythema, circulatory system disorders, shock, coma and other boric acid diseases.

Borax is an inorganic compound that appears primarily as a white powder containing colorless crystals. Borax has good water solubility, so it is widely used, common detergents, cosmetics, pesticides and other products have borax ingredients, but borax has a certain toxicity, and has been listed as a prohibited food addition by many countries in the world.
The chemical name of borax is sodium borate, also known as moonstone, mainly with sodium tetraborate decahydrate, sodium tetraborate pentahydrate, sodium anhydrous tetraborate and other products, these products have different characteristics and are mostly used in various experiments.
Borax is highly toxic, but trace amounts of borax are harmless to humans, but in the case of excessive ingestion of human body, it may cause a variety of poisoning symptoms in people, and serious may be fatal.
