A method of producing a metal form containing dispersed aerogel particles impregnated with polymers comprising a method of impregnating an aerogel with polymers, placing the aerogel impregnated with polymers within a dissolved polymer, cooling the dissolved polymer to create a polymer form with dispersed aerogel particles impregnated with polymers, adding molten metal to the polymer form, vaporizing the polymer form, replacing the polymer form with molten metal, and cooling the molten metal to yield a metal form containing dispersed aerogel particles impregnated with polymers. Dispersing the aerogel particles impregnated with polymers within the polymer form prior to adding molten metal allows the aerogel particles to be fully dispersed throughout the metal form.

A method for producing complexed particles including obtaining a good solvent solution, by dissolving Li.sub.2S, and LiX (X is at least one selected from a group consisting of F, Cl, Br, and I) in a good solvent, and precipitating particles by contacting the good solvent solution with a poor solvent having a temperature at least 165 C. higher than the boiling point of the good solvent, to evaporate off the good solvent. The method further satisfies at least one of the following: (i) the good solvent solution being obtained by further dissolving H.sub.2S in the good solvent, and (ii) H.sub.2S being dissolved in the poor solvent.

The present invention describes a process for purifying biodiesel without using a filter aid, in which purification of the biodiesel takes place by a sequence of washing operations after the reaction section, with stirring that is sufficiently vigorous to assist in the transformation of the molecules of esterified steryl glycosides, in order to convert them to a chemical form that can be removed by the process.

The present invention discloses a method for producing lithium carbonate from a low-lithium brine by separating magnesium and enriching lithium. A salt-lake brine is used as a raw material and is converted into halide salts through dehydration by evaporation and separation by crystallization; the halide salts are directly extracted using trialkyl phosphate or a mixture of trialkyl phosphate and monohydric alcohol, and an organic extraction phase as well as remaining halide salts are obtained after solid-liquid separation; reverse extraction is performed on the organic extraction phase to obtain a lithium-rich solution with a low magnesium-to-lithium ratio, and lithium carbonate is obtained after concentration and removal of magnesium by alkalization. The used solid-liquid extraction method is simple with no co-extraction agent used, and a solute distribution driving force is strong, unaffected by phase equilibrium of the brine extraction agent. The mass ratio of magnesium-to-lithium significantly decreases in the extraction phase.
