Lithium is only one fifth of the weight of the same volume of aluminum and one-half of the water. Lithium can not only float on the water, but even float on kerosene. If a plane is made of lithium, two people can lift it!
Bismuth exists in nature in the form of free metals and minerals. The metal Bismuth is obtained by calcination of minerals into Bismuth trioxide, followed by co-thermal reduction with carbon, and high-purity Bismuth can be obtained by fire refining and electrolytic refining.
Bismuth is a silvery white to pink metal that is brittle and easy to pulverize. Bismuth is chemically stable. Bismuth exists in nature in the form of free metals and minerals.
Lithium sulfate monohydrate, a colorless monoclinic crystal or a white crystalline powder, soluble in water, insoluble in acetone and absolute ethanol. The water solubility at 25 degrees was 25.7%. It has the effect of treating manic depressive psychosis. The crystal water was lost at 130 °C. Dissolved in 2.6 parts of water, almost insoluble in ethanol. The aqueous solution is neutral. The relative density is 2.06. The melting point is 859 ° C. The median lethal dose (mouse, oral) was 1190 mG/kG.
Notes when touching lithium oxalate
Lithium oxalate is a chemical substance that is slightly soluble in water and insoluble in ethanol and ether. English name: Lithium Oxalate. CAS number: 553-91-3. Molecular weight: 101.90. PSA: 80.26000.
Here are notes when touching lithium oxalate.
Pure Ceric Dioxide is a white heavy powder or cubic crystal. The impure products are light yellow or even pink to reddish brown (due to traces of strontium, barium, etc.). Almost insoluble in water and acid. The relative density is 7.3. The temperature of 1950 ° C, the boiling point: 3500 ° C. Toxic. Let me interduce uses of Ceric Dioxide:
1, Oxidizer. A catalyst for organic reactions. Steel analysis is used as a rare earth metal standard. Redox titration analysis. Decolorized glass. Glass enamel sunscreen. Heat resistant alloy.
Cerium trichloride, CAS: 7790-86-5, is an anhydrous anhydrous Cerium trichloride or Cerium trichloride polyhydrate that is irritating to the eyes, respiratory system and skin. Appropriate protective clothing is required. Used in petroleum catalysts, automotive exhaust catalysts, intermediate compounds and other industries. Also used in the manufacture of metal enamel.
Selenium is a chemical element with a chemical symbol Se, which is located in the fourth cycle of Group VI A in the periodic table of the chemical element and is a non-metal. It can be used as a photosensitive material, a catalyst for electrolytic manganese industry, a nutrient element essential for animals, and a nutrient element beneficial to plants.
The appearance of palladium is black powdery particles with a melting point of 1555 ° C and a boiling point of 3167 ° C. It is soluble in water.
Palladium is widely used in the hydrorefining and refining process of petrochemical, pharmaceutical, electronics, perfumery, dyestuff and other fine chemicals.
