A continuous process for producing a material of a battery cell using a system having a mist generator, a drying chamber, one or more gas-solid separators and a reactor is provided. A mist generated from a liquid mixture of two or more metal precursor compounds in desired ratio is dried inside the drying chamber. Heated air or gas is served as the gas source for forming various gas-solid mixtures and as the energy source for reactions inside the drying chamber and the reactor. One or more gas-solid separators are used in the system to separate gas-solid mixtures from the drying chamber into solid particles mixed with the metal precursor compounds and continuously deliver the solid particles into the reactor for further reaction to obtain final solid material particles with desired crystal structure, particle size, and morphology.

Disclosed are embodiments of tungsten bronze crystal structures that can have both a high dielectric constant and low temperature coefficient, making them advantageous for applications that experience temperature changes and gradients. In particular, tantalum can be substituted into the crystal structure to improve properties. Embodiments of the material can be useful for radiofrequency applications such as resonators and antennas.

A method for manufacturing particles including (a) bringing at least one starting material into a reactor, (b) subjecting the at least one starting material to a thermal treatment of a pulsating process gas stream in a treatment zone of the reactor, (c) forming particles, and (d) bringing the particles which are obtained in steps (b) and (c) out of the reactor. The at least one starting material is thermally treated in the treatment zone at a treatment temperature of 100° C. to 3000° C. and a retention time in the range of 0.1 s to 25 s, and temperature regulation of the process gas stream is decoupled from the generation and maintenance of a pulsation of the process gas stream. Also provided is a reactor for manufacturing particles according to the method.

A silicone-coated filler comprises: a particulate material mainly composed of an inorganic oxide formed by oxidizing a predetermined element; a first silicone structure bonded to a surface of the particulate material by way of a “-‘the predetermined element’-OSi—” structure; and a second silicone structure including a cross-linking structure with a carbon-carbon structure directly bonded to a silicon atom of the first silicone structure, and a polysiloxane structure bonded to the cross-linking structure.

The present invention relates to silicon-compound-coated fine metal particles, with which surfaces of fine metal particles, composed of at least one type of metal element or metalloid element, are at least partially coated with a silicon compound and a ratio of Si—OH bonds contained in the silicon-compound-coated fine metal particles is controlled to be 0.1% or more and 70% or less. By the present invention, silicon-compound-coated fine metal particles that are controlled in dispersibility and other properties can be provided by controlling the ratio of Si—OH bonds or the ratio of Si—OH bonds/Si—O bonds contained in the silicon-compound-coated fine metal particles. By controlling the ratio of Si—OH bonds or the ratio of Si—OH bonds/Si—O bonds, a composition that is more appropriate for diversifying applications and targeted properties of silicon-compound-coated fine metal particles than was conventionally possible can be designed easily.

A method for modifying a fine particle dispersion liquid has excellent dispersibility and dispersion stability. In this method for modifying a fine particle dispersion liquid having improved fine particle dispersibility, impurities included in an agglomeration of fine particles contained in the fine particle dispersion liquid are released into the dispersion liquid by applying physical energy to the agglomeration and performing dispersion processing for dispersion into particles that are smaller than the agglomeration of fine particles. The impurities are removed from the dispersion liquid by means of a removal unit provided with a filtration membrane before reagglomeration is caused by the impurities.
