Abstract: The present invention relates to a novel inorganic sulfate ion scavenger that is environmentally friendly and has high performance. With regard to the inorganic sulfate ion scavenger of the present invention, the amount of ionic impurities leaching out in pure water is no greater than 500 ppm and the amount of sulfate ion leaching out in pure water is no greater than 30 ppm. Furthermore, the present invention relates to an inorganic scavenging composition comprising the inorganic scavenger, and to an electronic component-sealing resin composition, an electronic component-sealing material, an electronic component, a varnish, an adhesive, a paste, and a product employing the inorganic scavenger or the inorganic scavenging composition.

Abstract: The present invention is to provide a silver-based inorganic antimicrobial agent that has excellent heat resistance and chemical resistance, that gives little resin coloration, and that has excellent processability. It has been found that the object can be attained by a silver ion-containing zirconium phosphate represented by Formula (1) below by limiting the production conditions to wet synthesis, and the present invention has thus been accomplished. Aga MbZrc(PO4)3.nH2O??(1) In Formula (1), M is at least one type of ion selected from an alkali metal ion, a hydrogen ion, and an ammonium ion, a, b, and c are positive numbers and satisfy 1.5?c?2 and a+b+4c=9, and n is no greater than 2.

Abstract: The invention provides a silver-based inorganic antibacterial agent dispersion that has excellent dispersibility and storage stability and allows the silver-based inorganic antibacterial agent to fully exhibit its antibacterial performance. Furthermore, it provides an antibacterial-processed product that is processed using this silver-based inorganic antibacterial agent dispersion. The silver-based inorganic antibacterial agent dispersion of the present invention is one that includes a silver-based inorganic antibacterial agent, a discoloration inhibitor, a thickener, a dispersant, and a dispersion medium. It is one that includes 5 to 60 parts by mass of the silver-based inorganic antibacterial agent in 100 parts by mass of the above dispersion, and 0.

Abstract: An antiviral agent is provided which is effective in treating coronaviruses and can be formed into various products whose efficacy sustainability is promising. In particular, the present invention provides an antiviral agent which is effective in treating a coronavirus, comprising a silver ion carrier; a product capable of inactivating a coronavirus, comprising the same; and a method of inactivating a coronavirus. The silver ion carrier is at least one selected from a compound represented by the following formula (1), potassium titanate, potassium uranate, potassium vanadate, potassium niobate, sodium tangustate, magnesium molybdate, calcium pentaborate, aluminosilicate, aluminum phosphate, nickel hexacyanoferrate, sepiolite, montmorillonite, silica gel, zeolite, ?-alumina, titanium oxide hydrate, hydroxyapatite and a glassy carrier.
