  • the hazardous substance is a malfunctioning device, and it is a result of harm to the user.
  • the base is alkaline with a concentration of 6-15 mol / l, so
  • the resulting dispersed metal powders have a greater active and reactive potential.
  • the developed method is distinguished by the simple technology and the equipment of the process, the standard can be used. Otherwise, the method will allow you to receive dispersed metallic impurities wide-
  • the proposed method is quite economical, since the recovery of a small hydride is reduced by 4 times.
  • the developed method of environmentally friendly harmless use of all the processed devices can be easy to neutral
  • the convenient method of operation is quick and easy to use, and the device is equipped with electronic devices.
  • Example 1 in case of use of another metal, external waste of this material will be lost through the optional equipment, after filtration and washing. After a short time, the metal hydroxide, processed by the other metal, is washed and washed, and the resulting powder is washed. 15 Example 1.
  • the dispersed nickel powder has a particle size of 3–30 nm; no impurities were found.
  • the dispersed bulk of copper has a particle size of 300–500 nm, a particle size of $ 10, and a sulfur content of 0.0001.
  • Example 4 The dispersed bulk of copper has a particle size of 300–500 nm, a particle size of $ 10, and a sulfur content of 0.0001.
  • Example 4 The dispersed bulk of copper has a particle size of 300–500 nm, a particle size of $ 10, and a sulfur content of 0.0001.
  • Target product $ 90 Example 4.
  • Dispersed nickel powder has a particle size of 3-30 nm. Consistency ⁇ sera $ 0.0001. Target product $ 90. Example 5.
  • the dispersion of the nickel due to the broadening of the particle size is 3-30 nm. There is no need for anything.
  • the resulting iron hydroxide is dried on air - for 3 hours. Removing the product at a temperature of 15 ° 350 ° C, which is 180 ° C higher than the temperature at the beginning of the recovery of iron hydroxide, at a consumption of 6 m / m of gas.
  • the obtained iron iron has a particle size of 3-30 nm. There is no need for anything.
  • the target price of the product is $ 90. 20 Example 7.
  • the resulting product composition is 35 -- ⁇ - 65 $ ⁇ ⁇ ⁇ ⁇ with an equal distribution of molybdenum in a ceramic matrix. He is not found.
  • Dispersed metal products can be used in agriculture, as a means of stimulating the production of land and in two cases for the purpose of remitting the property.
