    摘要: A particle formed of silica and carbon having a low impurity content and an excellent reactivity is provided. Also provided is a method of producing a silica and carbon-containing material including: (B) a carbon mixing step of mixing an aqueous alkali silicate solution having a silicon concentration within the liquid portion of at least 10 wt % with carbon so as to obtain a carbon-containing aqueous alkali silicate solution; and (C) a silica recovery step of mixing the carbon-containing aqueous alkali silicate solution with a mineral acid so as to cause carbon and silicon within the liquid portion to precipitate as particles formed of silica and carbon and thus obtaining a particle-containing liquid substance, then solid-liquid separating the liquid substance so as to obtain a solid portion of a silica and carbon-containing material which is an assembly of particles formed of silica and carbon and a liquid portion containing impurities.
