Zusammenfassung: | To provide a silver particle pellet produced by efficiently bringing fine silver particles into contact with an aqueous solution and permitting silver particle ionization of the aqueous solution by the fine silver particles and to provide a production method of the silver particle pellet.SOLUTION: The production of a silver particle pellet by bringing fine silver particles 3 into the contact with an aqueous solution and permitting ionization of the aqueous solution by the fine silver particles 3 comprises using a fine particle powder material for the silver particle pellet and as an aggregate a material which is not eluted as an ion into the aqueous solution such as titanium or spheres of titanium oxide (TiO) and alumina (AlO) and further adding carbon and common salt and burning at high temperature to form a communication hole 4. In other words, the porosity of the powder material is controlled by application of pressure to the above-mentioned composition in a casting mold to form an ant nest-like communication hole 4 reaching the inner layer of the silver particle pellet from the surface layer thereof. Through the communication hole 4, a passage of water reaching the inner layer from the surface layer of the silver particle pellet is assured and the fine silver particles 3 are brought into contact with the aqueous solution throughout the surface layer and the inner layer of the silver particle pellet.SELECTED DRAWING: Figure 1
【課題】微細銀粒子を水溶液に効率的に接触させて、前記水溶液を前記微細銀粒子によって銀粒子をイオン化する銀粒子ペレット及びその製造方法を提供する。【解決手段】 微細銀粒子3を水溶液に接触させて、前記水溶液を前記微細銀粒子3によってイオン化する銀粒子ペレットを製造する際に、前記銀粒子ペレットの微粒子粉体材料と骨材としてチタン、あるいは酸化チタン(TiO2)やアルミナ(Al2O3)の球体などイオンとして水溶液に溶出しない素材を用い、さらに炭素や食塩を添加して高温中で燃焼させることによって、連通孔4を形成する。つまり、上記組成を鋳型内で加圧することにより、前記粉体材料の多孔率を調節し、銀粒子ペレットの表面層から内部層に達するアリの巣状態の連通孔4を形成している。この連通孔4により、銀粒子ペレットの表面層から内部層に至る水の通路を確保し、銀粒子ペレットの表面層及び内部層に渡って微細銀粒子3を水溶液に接触させている。【選択図】図1 |
