The lithium salt solution and the organic cobalt compound solution are prepared according to a certain ratio, and are added or mixed separately from the feeding tube 1〇4, and then added to the reaction chamber, the water phase has no phase and will be divided into two layers, and the organic inscription solution is located in the upper layer. The brine solution is located in the lower layer. Start to leave 2G from d, and set the reaction conditions to make the centrifuged fresh (four) 3 pairs of reactants to high-speed centrifugation. The high-speed centrifuge cake is ordered, and the water phase has no phase to form a water-in-oil microemulsion. Under the 'generating nano training. In the present embodiment, the _ high-speed centrifugal sample-feeding action can form a microemulsion without adding a surfactant, and the side effects caused by the (4) surfactant-free microemulsion. ^ Normally, the rotation speed of the centrifugal agitator 203 is not lower than i〇〇〇〇r/min, and the specific rotation speed is specifically set according to the particle size of the synthetic lithium nanocobaltate and other performance requirements.

The synthesis step is similar to the first embodiment except that the reaction process forms two microemulsion systems. The specific process is as follows: firstly, an aqueous solution of silver nitrate is provided as an aqueous phase reactant, and the oil phase reactant is an organic solvent, such as a liquid direct-bonded soot or a ring-burning hydrocarbon, and the silver citrate aqueous solution is mixed with an organic solvent, and then subjected to high-speed centrifugation. Stirring to form a first microemulsion system; secondly, using an aqueous solution of sodium chloride as an aqueous phase reactant, and an oil phase reactant as an organic solvent, such as a liquid linear alkane or a cycloalkane, etc., after mixing the aqueous sodium carbonate solution with an organic solvent, The high-speed centrifugal stirring is performed to form a second microemulsion, and the first micro-emulsion is mixed with the second micro-emulsion, and subjected to high-speed centrifugal stirring to react to form a nano-silverized product. The nano-vaporized silver product is solid, insoluble in water and organic solvents, and can be separated from the reaction mixture by filtration. Both of the above embodiments illustrate the process of synthesizing nanoparticles by taking a synthetic nanometal salt as an example. The third embodiment of the present invention, such as the synthesis of nano metal particles, is a process of synthesizing a strip of rice particles, and the metal particles to be synthesized thereof are nano nickel. The over-paving is like the second embodiment. First, the first microemulsion system is prepared by using a vaporized nickel (NiCl2) solution and an organic solvent as a raw material; secondly, the second micro-Wei-age is reduced by a reducing money solvent machine. In the method, ammonia water and organic solvent are used to make the second microemulsion age; again, the first-micro-reduction system is mixed with the second micro-liquid material, and subjected to high-speed centrifugation to react to form nano-recorded particles. Finally, the nano nickel is separated from the reaction mixture by a transition. = Technical schemes The fine-implemented formula, such as pure silk oxides, is a synthetic nanoparticle, wherein the metal oxide to be synthesized is triiron tetroxide. The process is similar to the second method. The first microemulsion is prepared by using a ferrous chloride or ferric chloride solution and an organic solution as a raw material, and the second microemulsion system is prepared by using ammonia water and an organic solvent as raw materials; The system is combined with the __microemulsion (4) '6' and subjected to a high-speed separation (four) to cause a reaction of 9 8 1330546 to dry and dry the dentine nano-iron trioxide powder. In this embodiment, the reactant ferrous chloride or the iron-iron solution and the ammonia water are both aqueous reactants, and the direct mixing does not form a microemulsion system. The embodiment uses the method of forming the microemulsion in the first embodiment. The two microemulsion systems are formed to carry out the reaction of the ferroferric oxide product; the advantage is that the microparticles can be used to react the nanoparticles when the reactants are not necessarily in the aqueous phase and the oil phase. Similarly, in the second embodiment and the third embodiment, the reactants participating in the reaction are also aqueous phase materials, and similarly, two microemulsion systems are formed by the method of forming the microemulsion in the first embodiment to react to obtain the naphthalene. Rice particles.
