A fine silver particle-containing composition includes a large number of fine silver particlesand a coating layerthat covers a surface of each silver particle. The silver particleis a so-called nano particle. The silver particlehas a scale-like shape. The coating layerconsists of an organic compound. The organic compound binds to the silver particle. The organic compound suppresses aggregation of the silver particle. The composition is in a cake form. A weight ratio of the organic compound with regard to the total amount of the composition is not lower than 2% but not higher than 15%.

Fine metal particle-containing composition

A process for synthesizing nano-sized rutile, anatase, or a mixture of rutile and anatase TiOpowder. The process includes the steps of: 1) forming a Ti-peroxo complex by mixing HOwith a Ti compound, and 2) heating the Ti-peroxo complex at a temperature of above 50&#xb0; C. A primary particle size of TiOparticles, synthesized by the method, is below 50 nm, and an agglomerated particle size thereof after a washing/dry process is below about 10 &#x3bc;m. The major characteristics of the present invention are that it is a low temperature process, a highly concentrated synthesis, and high production yield of above 90%.

Low temperature process for producing nano-sized titanium dioxide particles

The present invention is directed to methods for forming nanosized metal particles. Preferably, nanosized noble metal particles are formed. According to the methods of the invention, a product containing nanosized metal particles in a solvent are formed. Additionally, processing to remove undesirable byproducts created or used during the fabrication process are not necessary.
