Lithium molybdate molecular weight 173.84000, Chinese alias lithium molybdate, transparent liquid, soluble in water, insoluble in organic solvents, water solubility 44.8, melting point 705 C, density 2.66 g/cm is mainly used in chemical industry, corrosion inhibitors, electrode materials, cermet, resistor materials, refrigeration and other fields, especially in the refrigeration industry has broad market prospects.
Scientists have made extensive research on molybdate materials of transition metals. It is found that lithium molybdate has a certain corrosion inhibition effect on carbon steel in lithium bromide solution, which is stronger than lithium chromate; lithium molybdate has a certain corrosion inhibition effect on carbon steel in lithium bromide solution at high temperature, which can effectively repair the surface defects of carbon steel caused by corrosion in lithium bromide solution at high temperature. The bromination of lithium molybdate was found by XRD, AES, SEM and XPS analysis. Molybdenum dioxide film was formed on the surface of carbon steel in lithium solution.
Lithium molybdate is mainly used in chemical industry, corrosion inhibitor, electrode materials, cermet, resistor materials, refrigeration and other fields, such as:
1. Corrosion resistance: Lithium bromide solution has strong corrosiveness to carbon steel. Adding 0.20 mol/L lithium hydroxide to lithium bromide solution to adjust the pH value, and adding 0.020 mol/L lithium molybdate can effectively inhibit the corrosion of lithium bromide solution to carbon steel, which has obvious corrosion inhibition effect. Polarization curves, scanning electron microscopy and X-ray diffraction show that lithium molybdate forms a continuous passivation film on the surface of carbon steel, which is composed of ferrous oxide, lithium molybdate and molybdenum trioxide to block the anodic reaction.
2. A nickel-rich cathode material for lithium molybdate surface-modified lithium-ion batteries was prepared.
Lithium molybdate is generally slightly harmful to water bodies. Do not expose undiluted or large quantities of products to groundwater, waterways or sewage systems. Do not discharge materials into the surrounding environment without government permission.
