The invention addresses the problem of providing a method for producing microparticles. Provided is a method for producing microparticles. For the first process, seed microparticles are separated in a thin film fluid that forms between at least two processing surfaces, which are disposed facing each other, which can approach or separate from each other and at least one of which rotates relative to the other, and the fluid comprising the separated seed microparticles is discharged as a discharge fluid. Subsequently, for the second process, the separated seed microparticles are grown in the discharged discharge fluid to obtain the intended microparticles. Uniform and homogeneous microparticles are obtained as a result of the microparticle producing method comprising the two process.

The present invention addresses the problem of providing a novel, sold metal alloy. Provided is a metal alloy containing two or more types of metal, wherein an equilibrium diagram of the metal alloy shows the two or more types of metal in a finely mixed state at the nanolevel in a specific region where the two types of metal are unevenly distributed. This metal alloy has a substitutional solid solution of the two or more types of metal as the principal constituent thereof. This metal alloy is preferably one obtained by precipitation after mixing ions of two or more types of metal and a reducing agent in a thin-film fluid formed between processing surfaces, at least one of which rotates relative to the other, which are arranged so as to face one another and are capable of approaching and separating from one another.

Provided is a method for producing a nanoparticle. Provided especially is, in the method for producing a nanoparticle to separate a diketopyrrolopyrrole pigment, a method for separating an α-type diketopyrrolopyrrole pigment nanoparticle having high crystallinity by carrying out separation of the diketopyrrolopyrrole pigment and crystal type transformation to the α-type with substantially a single step. The α-type diketopyrrolopyrrole pigment nanoparticle is separated by mixing a diketopyrrolopyrrole pigment solution having the diketopyrrolopyrrole pigment dissolved in a solvent and an alcohol solvent containing an alcohol compound solvent in a thin film fluid formed between at least two processing surfaces 1 and 2 arranged to be opposite to each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other. The method is characterized in that an acidic substance is contained in at least any one of the diketopyrrolopyrrole pigment solution and the alcohol solvent at this moment.

Equipment for treating a matter to be treated more stably and uniformly between approaching/receding treatment planes in a treatment section where at least one plane can rotate relatively to the other plane. Treatment is performed by introducing a first fluid containing a matter to be treated between the treatment planes, introducing a second fluid containing the matter to be treated between the treatment planes from a channel independent from the channel which introduced the first fluid and communicating with the space between the treatment planes and then mixing and stirring them between the treatment planes. The outlet portion of the channel introducing the second fluid to the space between the treatment planes is provided with a plurality of split channels.
