Open Data Verified Data
lime sintering method: spodumene concentrate (generally containing 6% of lithium oxide), mixed with limestone and finely ground, sintered at 1150~1250 ℃ to produce lithium aluminate and calcium silicate, which are crushed by wet grinding, the lithium hydroxide is leached with a washing solution, filtered by sedimentation, and the leaching solution is concentrated by evaporation to form a lithium hydroxide monohydrate product.
The Lithium sulfate solution undergoes a metathesis reaction with caustic soda to form a mixture of sodium sulfate and lithium hydroxide solution. The significant difference in solubility at low temperatures between sodium sulfate and lithium hydroxide monohydrate was exploited to separate the two. The method comprises the following steps: adding sodium hydroxide to the Lithium sulfate solution of roasting, acidification, pulping, leaching and preliminary concentration of the lithium concentrate to obtain a mixture of sodium sulfate and lithium hydroxide solution; the mixed solution is cooled and frozen to 5 ~-10 °c, and the sodium sulfate is separated after crystallization; The clear liquid separated by freezing is heated, evaporated and concentrated; Crystallized and separated, to obtain lithium hydroxide monohydrate crude I-water lithium hydroxide crude water dissolved, add barium hydroxide, the formation of insoluble barium sulfate, filtered, filtered solution by evaporation concentration, crystallization, separation, to obtain wet lithium hydroxide monohydrate; drying gave hydrogen and oxygen monohydrate.

Open Data Verified Data
This product dust has a stimulating effect on eyes, skin and respiratory system. The aqueous solution is an alkaline corrosive liquid. Explosion hazard: This product combustion, corrosive, irritating, can cause human burns. Hazard characteristics. Strong oxidant. In particular, with the wetting of a small amount of water, the mixture with the combustible substance burns under slight collision or friction. The aqueous solution is an alkaline corrosive liquid. Emergency treatment and disposal methods: emergency treatment of leakage Isolation leakage contaminated area, restricted access. It is recommended that emergency personnel wear self-suction filter dust masks and work clothes. Do not come into direct contact with the leakage. Do not make the leakage contact with organic matter, reducing agent and combustible. A small amount of leakage, to avoid dust, carefully sweep up, collected in a sealed container to be marked, waiting for processing. Large leakage: Cover with plastic cloth and canvas to reduce scattering. It is then collected for recycling or transported to a waste disposal site for disposal. Protective measures: Respiratory system protection: it is recommended to wear self-priming filter dust mask when it may come into contact with dust. Eye protection: wear chemical safety glasses. Body Protection: wear polyethylene anti-virus clothing. Hand Protection: wear neoprene gloves. Other: no smoking, eating or drinking at work site.

| Toxicity | Strontium peroxide is a strong oxidant. Dust can irritate the eyes, skin and respiratory system. The aqueous solution is alkaline and has a corrosive effect. Staff should wear masks, gloves and protective glasses. When inhaling dust, the patient should be removed from the scene, placed to rest and keep warm. The eyes are irritated and immediately rinsed with plenty of water. Skin contact first rinse with plenty of water, then wash thoroughly with soap. Immediately gargle, drink water and send to hospital for first aid. |
| use | strontium peroxide can be used as a flame-inducing agent for tracer, shells and fireworks, and an oxide cathode material. It is also used in bleaching and pharmaceutical industries. It can also be used as a deposition inhibitor in an internal combustion engine. It can be used to determine hemoglobin in plasma and urine. Using the performance of strontium peroxide in nitrogen to separate into oxides, it can be used as a raw material for the preparation of metallic strontium. Used as oxidant |
| production method | dehydration method strontium peroxide octahydrate can be converted into strontium peroxide after drying at 105Pa and 110~120 ℃. SrO2?8H2O[△]→ SrO2 + 8H2O can produce products containing 95% SrO2 by dehydration. Strontium peroxide is prepared by direct synthesis of strontium metal or strontium oxide under heating reaction at 400~500 ℃ and oxygen pressure of 15 × 106Pa. Its SrO 0.5O2 → SrO2 slurry containing hydrogen peroxide interacts with strontium oxide or strontium hydroxide to produce strontium peroxide. Its Sr(OH)2 + H2O2 → SrO2 + 2H2O interacts with high purity strontium nitrate, ammonia water and hydrogen peroxide to produce 99% purity strontium peroxide. Strontium nitrate can also react with potassium peroxide (or sodium peroxide) in liquid ammonia at -30°C to produce strontium peroxide. |
