Patent number: 8034155Abstract: Nanosilver porous material particles and method for manufacturing the same are disclosed. The nanosilver porous material particles include nanosilver particles distributed on the surface thereof. First, a nanosilver precursor is dissolved in water and a proper quantity of a fixation agent is added to form a solution. Next, a proper quantity of the porous material particles is added into the solution and that is mixed well to form a suspension. Next, the suspension is allowed to stand for a predetermined period of time, and then the suspension is filtered to separate the porous material particles from the solution. Finally, the resulting porous material particles are baked and dried.Type: GrantFiled: July 17, 2008Date of Patent: October 11, 2011Assignee: Apex Nanotek CorporationInventors: Chiao-Cheng Chang, Austin Tsao

Patent number: 8012408Abstract: A metal powder manufacturing device for manufacturing a metal powder includes a feed for supplying a molten metal, a fluid spout unit, and a course modification unit. The fluid spout unit further includes a channel and an orifice. The channel is provided below the feed, allowing passing of the molten metal supplied from the feed. The orifice is opened at a bottom end of the channel, spouting a fluid into the channel. The above course modification unit is provided below the fluid spout unit, and forcibly changes the traveling direction of a dispersion liquid. This dispersion liquid is composed of multiple fine droplets dispersed into the fluid. The above droplets are a resultant of a breakup caused by a contact between the molten metal and the fluid ejected from the orifice. Here, the dispersion liquid is transported so that the droplets is cooled and solidified in the dispersion liquid in order to manufacture the metal powder.Type: GrantFiled: March 29, 2007Date of Patent: September 6, 2011Assignee: Seiko Epson CorporationInventor: Atsushi Watanabe

Publication number: 20110209577Abstract: The invention relates to an apparatus and a process for granulating a metal melt. The apparatus substantially comprises a round water tank, into which water is injected in a tangential direction with the aid of a number of nozzles, so that the water in the tank rotates and forms a parabolic surface. The nozzles are arranged such that they are distributed in height and around the circumference of the tank wall. The uppermost nozzle is located in the region of the surface of the water and produces a stream of water or fan of water lying in the surface of the water. For granulating a metal melt, it is poured continuously from a melting crucible into the stream of water or fan of water of the uppermost nozzle.Type: ApplicationFiled: October 29, 2009Publication date: September 1, 2011Applicant: UMICORE AG & CO.
