LITHIUM PHOSPHATE (ORTHO) - Preparation Method
Open Data Verified Data
industrial production generally uses lithium hydroxide monohydrate or lithium carbonate as raw material, and phosphoric acid reaction to obtain lithium phosphate. Phosphoric acid method: the industrial lithium hydroxide monohydrate is added into the reactor containing distilled water, and the thermal phosphoric acid is slowly added under stirring for neutralization reaction to generate lithium phosphate precipitate
Precipitation, filtration, distillation and concentration, cooling crystallization, centrifugal separation, drying, to prepare lithium phosphate product.

Open Data Verified Data
has a significant stimulating effect, can stimulate the skin and mucous membranes, gastrointestinal tract and central nervous system damage. Production personnel should wear work clothes, protective masks, latex gloves and other labor protection articles to protect the respiratory organs and skin. Production equipment should be sealed and the workshop should be well ventilated. The product is sealed in a double-layer polyethylene plastic bag, each bag has a net weight of 5kg. Four bags are sealed into a polyethylene plastic bag, and the middle is a three-layer Kraft paper bag. Both inside and outside packaging are indicated with red paint: manufacturer name, product name, product brand, batch number, net weight, packaging date and moisture-proof sign. Should be stored in a cool, ventilated, dry, clean warehouse. The packaging must be sealed and protected from moisture. They shall not be co-stored with acids and hazardous substances. During transport, be careful to prevent rain and sun exposure. When loading and unloading should be light to prevent packaging damage. Fire can be suppressed with water, dry sand, and all kinds of fire extinguisher.
