摘要： A method for synthesizing high purity silver particles and colloids without requiring the addition of either surfactants or reducing agents thereto, or requiring only a minimal amount thereof. The synthesizing process comprises: (i) a silver oxalate synthesizing process; (ii) a process of dispersing silver oxalate into an appropriate carrier; and {iii) a process of heating said silver oxalate dispersed into said carrier at a temperature of at least 100° C. Silver particles and colloids of various form factor and size may be synthesized depending upon the reaction conditions, the carrier, and the type of surfactant.

摘要： A process for synthesizing nano-sized rutile, anatase, or a mixture of rutile and anatase TiO2 powder. The process includes the steps of: 1) forming a Ti-peroxo complex by mixing H2O2 with a Ti compound, and 2) heating the Ti-peroxo complex at a temperature of above 50° C. A primary particle size of TiO2 particles, synthesized by the method, is below 50 nm, and an agglomerated particle size thereof after a washing/dry process is below about 10 μm. 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%.

摘要： A method for synthesizing TiO2, metal-doped TiO2, and metal-coated TiO2 particles of spherical form factor and needle type of which the average particle size is below 150 nm. The method of the invention is to synthesize Ti(OH)4, metal-doped Ti(OH)4 or metal-coated Ti(OH)4, and react the same by applying a pressure above the saturated vapor pressure at a temperature above 100° C. The pressure is achieved by means of the pressure of the vapor generated during the reaction inside of a closed reactor, by pressure applied from the outside, or a mixture of both. Gases to increase the pressure from outside are preferably inert gases such as Ar and N2 but are not limited to inert gases.
