    摘要： An iron powder for an exothermic composition according to the present invention has a bulk density of 0.3 to 1.5 g/cm3. Furthermore, an exothermic composition according to the present invention contains the iron powder, a carbon material, a halide salt, and water. Furthermore, an exothermic body production method according to the present invention includes: forming a coated member by coating a base material sheet with a flowable exothermic composition containing the iron powder, a carbon material, and water; and adjusting an amount of moisture in the coated member by removing water from the coated member. Furthermore, the present invention is directed to a production method for the iron powder (an iron powder for an exothermic composition) including: a reducing step of reducing iron oxide to obtain reduced iron; and a step of milling the reduced iron. In the reducing step, the iron oxide is reduced by introducing iron oxide and a solid reductant with a volatile matter content of 10% by mass or more into a heating furnace whose internal portion contains no sulfur gas or is set to an air or inert gas atmosphere, and setting the internal portion to a reducing gas atmosphere through heating under a condition that an ambient temperature of the internal portion is from 900 to 1000° C.

    摘要： 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.
