Lithium hydroxide represents colourless hydroscopic crystals with tetragonal lattice, is well dissolved in water (allocates heat), we will dissolve in ethanol a little. Is the strong basis, treats alkalis. Aqueous solutions have silnoshchelochny reaction. Fusions and its aqueous solutions destroy glass, porcelain, interact with many silicates, subject to corrosion some metals. On air absorbs carbon dioxide gas and forms lithium carbonate.

Density is 1,46 g/cm ³. Temperature of melting is 462 °C, temperature of boiling is 925 °C.

Chemical formula: LiOH.

Technical hydrate of lithium oxide is received by method of interaction of lithium metal or lithium oxide with water or interaction of lithium carbonate with calcium hydroxide.

It is used as absorber of carbon dioxide gas in gas masks, submarines and spaceships.
It is also used as polymerization catalyst.
It is applied in the glass, ceramic and radio engineering industry.
It is also used by production of the waterproof lubricants possessing mechanical stability at considerable change of temperature (from-60 to 160 °C).
Ispolzuntsya as additive to electrolyte for alkaline accumulators. Replacement in the alkaline accumulator of potassium hydroxide by lithium hydroxide leads to increase in its endurance twice.

Physical and chemical indicators of state standard specification 8595-83 lithium hydroxide.

Lithium hydroxide safety requirement.
The lity hydroxide technical is fire and explosion-proof, on extent of impact on organism belongs to substances of the 1st class of danger.

Toxicity degree 3
Main properties and types of danger
Main properties Solid matter. The powder, crystals or granules blurring on air. Colourless or white, flavourless. It is hygroscopic. It is soluble in water. At interaction with water the warming up is possible. Neletucha. Korrozionna for some metals. On air absorbs carbon dioxide gas and forms lithium carbonate which toxicity is defined by availability of lithium.
Vzryvo-and fire danger Negoryucha.
Danger to the person Pyretic. Possesses all-toxic action on human body and the expressed local irritant action on skin, mucous membranes of upper airways and eyes. It is dangerous at inhalation, hit on skin and in eyes. Cough, constraint in breasts, cold, dacryagogue, skin burn, has swelled century, sharp reddening of conjunctiva, defeat of iris of the eye. Chemical burn.
Means of individual protection The isolating protective KIH-5 suit complete with the isolating gas mask IP-4M or protective general L-1 or L-2 suit complete with industrial gas mask with the boss In, gloves from butyl rubber dispersion, special footwear.
At small concentration in air (at increase of maximum concentration limit to 100 times) - overalls, autonomous protective individual set with forced feed in zone of breath of cleaned air with cartridges of ROM, PZ-2 filtering respirator of "FORT-P", universal respirator of "Snezhok-KU-M".
Necessary actions in emergencies
General character To take away the car to the safe place. To isolate dangerous zone in radius not less than 50 m. To modify the specified distance by results of chemical investigation. To remove strangers. To enter dangerous zone in protective agents. Injured to give first aid.
At leak, flood and scattering To report in TsSEN. Not to touch prosypanny substance. To protect with Prosypaniya with earth shaft, to fill up with dry inert material, to collect in the dry tanks protected from corrosion, to close hermetically.
At the fire Does not burn.
Neutralization To fill up scattering with dry sand, to collect in the dry, protected from corrosion tanks with observance of precautionary measures. To wash out the place of scattering large amount of water from the maximum distance, to obvalovat and not to allow hits of substance in surface waters. To process the washed-out surfaces of rolling stock and the territory weak acid solution.
Measures of first aid At hit on integuments it is necessary to wash out immediately large amount of water, then to process affected area 1-2% solution of boric acid.
At hit in eyes it is necessary immediately and long to wash out them plentiful water jet, then 1-2% solution of boric acid. It is not necessary to rub eye. After first-aid treatment it is necessary to address to medical institution.

Packaging, transportation and storage.
Hydrate of lithium oxide technical is packed into bags from polyethylene film which put previously in steelpans with a capacity of 100 dm ³. The plastic bag with product is made.
Lity the hydroxide is transported any kinds of transport, except air, in the covered vehicles according to rules of the transportation of goods operating on this type of transport.
Lithium hydroxide is stored in warehouse with natural ventilation in the conditions excluding condensation of moisture on container surface.
Warranty period of storage - 10 years from the date of production.
