colorless block crystal. The relative density was 3. 92. Melting point 848 °c. Boiling point 1727 °c. Soluble in water, acetone and acid. Deliquescence.
Rare Earth ammonium double salt method: using rare earth ammonium sulfate double salt as raw material, the sodium hydroxide is converted into rare earth hydroxide, and then the air is oxidized to tetravalent cerium, and the cerium is enriched by dilute hydrochloric acid leaching, after dissolution, extraction and crystallization, cerium chloride was obtained.
used as petroleum catalyst, cerium salt raw material. It is also used to make metal cerium, etc.
packed in two-layer polyethylene plastic bags, with an iron barrel. 200kg net weight of each bag. Should be stored in a ventilated, dry warehouse. This product is easy to absorb moisture, storage and transportation process should prevent package breakage, keep dry. Toxicity and protection: see cerium oxide products.
