Solid phase (plural solid phases) (physics) One of the three fundamental structural phases of matter in which the cohesive force of matter is strong enough to keep the molecules or atoms in the given positions, restraining the thermal mobility.

Preparation of multi-position doped lithium iron phosphate positive electrode material and application thereof

The invention discloses a preparation method of a multi-place doped lithium iron phosphate anode material and an application thereof, which belong to the technical field of the preparation of electrochemical power materials. The multi-place doped lithium iron phosphate anode material is expressed by the following formula: Li1-xAxFe1-yByP1-zCzO4Ddelta, wherein, at least two of x, y, x and delta can not be expressed zero at the same time. Multi-place doped anode material lithium iron phosphate powder which is used in a secondary lithium-ion battery and has good crystallization performance and even composition is prepared by adopting a solid phase method and a simple mixing and drying process; compared with the method doping in a certain crystal lattice place, the multi-place doped anode material lithium iron phosphate powder has wide doping material source, which can greatly improve the basic capacity and cycling electrical performance of matrix and is applied to a stable industrialized production and non-high-purity materials. The multi-place lithium iron phosphate of the invention is taken as the anode material and is usually used in the secondary lithium-ion battery and the secondary lithium-ion battery is taken as a power source.

Composition, method of making, and treatment of wood with an injectable wood preservative slurry having biocidal particles

A method of preserving wood includes injecting into the wood an effective amount of a aqueous wood-injectable biocidal slurry, said a wood-injectable biocidal slurry containing dispersants and sub-micron biocidal particles selected from at least one of the following classes: 1) a plurality of particles containing at least 25% by weight of a solid phase of sparingly soluble salts selected from copper salts, nickel salts, tin salts, and/or zinc salts; 2) a plurality of particles containing at least 25% by weight of a solid phase of sparingly soluble metal hydroxides selected from copper hydroxide, nickel hydroxide, tin hydroxide, and/or zinc hydroxide; 3) a plurality of particles containing at least 25% by weight of a solid phase comprising a substantially-insoluble organic biocide selected from triazoles, chlorothalonil, iodo-propynyl butyl carbamate, copper-8-quinolate, fipronil, imidacloprid, bifenthrin, carbaryl, strobulurins, and indoxacarb; 4) a plurality of particles containing on the outer surface thereof a substantially-insoluble organic biocide; 5) a plurality of particles containing a solid phase of a biocidal, partially or fully glassified composition comprising at least one of Zn, B, Cu, and P. The particles may advantageously contain metallic copper, a leachability barrier, pigments, dyes, or other adjuvants disposed on the outer surface thereof.

Method and system for processing oil field wastes

The embodiment of the invention discloses a method and a system for processing oil field wastes. The method for processing the oil field wastes comprises the following steps: conveying initial materials to a heating cavity, and heating the heating cavity by using high-temperature flue gas, so as to obtain mixed steam and solid residues; carrying out condensation and separation on the mixed steam, so as to obtain oil, water and a noncondensable gas, wherein the oil and the noncondensable gas are used for combusting to obtain the high-temperature flue gas, and the solid residues are discharged out of the heating cavity. According to the method, the heating cavity is indirectly heated by using the high-temperature flue gas, so that the initial materials inside the heating cavity are subjected to thermal decomposition, solid residues free of oil, the noncondensable gas and oil are obtained from the mixed steam generated by thermal decomposition after a series of treatments, and then the noncondensable gas and oil are used for combusting to generate the high-temperature flue gas. Compared with the prior art, the method disclosed by the invention has the advantages that decomposition is carried out without adding a cracking agent, and thermal decomposition can be directly carried out on the oil field wastes in different regions, therefore, the method and the system are better in universality.
