摘要： The purpose of the present invention is to provide a nonaqueous electrolyte battery having excellent lifespan characteristics and/or excellent safety, which are essential in practice. The basic inorganic particles for a nonaqueous electrolyte battery according to the present invention include basic inorganic particles, wherein a hydrophilicity parameter A for the basic inorganic particles satisfies the expression: 0.45≤A(BET1/BET2)≤2.0. In the expression, BET1 represents the specific surface area of the basic inorganic particles calculated from an adsorption isotherm which is measured through adsorption of water vapor to the basic inorganic particles by a BET method. BET2 represents the specific surface area of the basic inorganic particles calculated from an adsorption isotherm which is measured through adsorption of nitrogen to the basic inorganic particles by a BET method.

摘要： Methods and systems for producing activated silicate materials are disclosed. A silicate source material is provided for reaction with a reforming agent in a reforming process. The reforming process is a hydrothermal process and/or a high temperature silicate reforming (HTSR) process. The reaction materials are brought to the suitable reaction temperature via a heat source in the presence of the suitable reaction medium. The activated silicate materials exhibit improved reactivity compared to non-activated silicate materials and thus are advantageously employed in elemental extraction processes to produce a valuable material product.

摘要： Methods and systems for producing highly activated silicate materials are disclosed. A silicate source material is provided for reaction with a reforming agent in a reforming process. The reforming process is a hydrothermal process and/or a high temperature silicate reforming (HTSR) process. The reaction materials are brought to the suitable reaction temperature via a heat source in the presence of the suitable reaction medium. For the hydrothermal reaction process, the reaction medium and heat source can be exhausted steam that is the byproduct of another industrial process. For the HTSR process, the silicate source material and the heat source can be a molten slag byproduct from another industrial process. The activated silicate materials exhibit improved reactivity compared to non-activated silicate materials and thus are advantageously employed in elemental extraction processes to produce a value material product. By being integrated with the utilization of industrial waste heat, like molten slag heat utilization (MSHU), and the recycle of the reforming agents, the production of activated silicate based materials can base on sustainable energy and materials.

摘要： Industrial demand for hexafluorosilicic acid (H2SiF6) is often lower than the amount produced from fluoride recycling processes. One alternative for using this surplus is manufacturing a soil conditioner by neutralizing the hexafluorosilicic acid with calcium oxide (CaO) inside an open, Kullman type reactor. The reaction ensures alkalinity to the soil conditioner having a pH of about 10, moisture less than about 40%, phosphorus (P2O5) at about 2.5%, calcium at about 22%, about 0.5% magnesium, about 10% silicon (about 30% to 40% water-soluble), about 18% fluoride, neutralization power of about 5% to 15%, and total neutralization power of about 5% to 12%. The resulting product, called AgroSiCa, is easily manageable with very high contents of Ca and Si (total and soluble), and also contains Mg, P, Fe, Zn, and F. When applied to soil, it contributes to the supply of nutrients, provides a better root growth and improves the plants development.

摘要： A method for activation of magnesium silicate minerals by conversion to magnesium hydroxide for sequestration of carbon dioxide (CO2) is provided. The method includes heating a dry solid-solid mixture of an alkaline earth Silicate-based material with an alkali metal compound at a temperature below 300 C to form a solid product predominantly comprising a mixture of magnesium hydroxide and alkali metal silicate, wherein the Silicate-based material comprises a naturally occurring Olivine, Serpentine mineral and alkali metal silicate. The method includes a subsequent dissolution of the solid product in aqueous solution to form an alkaline aqueous liquid slurry, comprising solid and aqueous phase products and the reaction of the solid phase thus formed with Carbon Dioxide (CO2), producing a metal Carbonate. The method provides a process that has shown significant cost and energy efficiencies for producing magnesium hydroxide and CO2 sequestration via mineral carbonation.
