The powder is produced by continuously feeding at least one vaporous or gaseous silane and optionally at least one vaporous or gaseous doping substance and an inert gas into a reactor and mixing the components there, wherein ... 06/07/07 - 20070128099 - Silicon feedstock for solar cells The present invention relates to silicon feedstock for producing directionally solidified silicon ingots, thin sheets and ribbons for the production of silicon wafers for PV solar cells where the silicon feedstock contains between 0.2 and 10 ppma boron and between 0.1 and 10 ppma phosphorus distributed in the material. The ... 05/24/07 - 20070116622 - Increased stability low concentration gases, products comprising same, and methods of making same Methods of passivating a metal surface are described, the methods comprising the steps of i) exposing the metal surface to a silicon-containing passivation material; ii) evacuating the metal surface; iii) exposing the treated surface to a gas composition having a concentration of reactive gas that is greater than an intended ... 11/09/06 - 20060251562 - Porous silicon particles Porous silicon particles are prepared from a metallurgical grade silicon powder having an initial particle size greater than about 1 micron is presented. Each porous silicon particle comprises a solid core surrounded by a porous silicon layer having a thickness greater than about 0.5 microns. ... 11/09/06 - 20060251561 - Silicon nanosponge particles Silicon nanosponge particles prepared from a metallurgical grade silicon powder having an initial particle size ranging from about 1 micron to about 4 microns is presented. Each silicon nanosponge particle has a structure comprising a plurality of nanocrystals with pores disposed between the nanocrystals and throughout the entire nanosponge particle. ... 10/26/06 - 20060239885 - Bismuth-containing pigment solid solutions The invention relates to novel colorants based on bismuth oxyhalide and bismuth oxycarboxylates, bismuth oxyenolates or bismuth oxysulfonates and to the use thereof as pigments and coating agents. They are preferably solid solutions, especially solid solutions mainly in the tetragonal crystal lattice of bismuth oxyhalide. ... 08/24/06 - 20060188425 - Process for the storage of hydrogen using a system that strikes a balance between an alloy of alkaline metal and silicon and the corresponding hydride XLi=1 ... 07/13/06 - 20060153763 - Silica-supported polymerisation catalyst A process for the preparation of a silicon containing transition metal compound comprises the steps of (a) non-hydrolytic sol-gel condensation of a silane of formula LxSiQn wherein L is a π-bonded ligand, Q is an anionic ligand, and x+n=4 with a halogenated silane (or siloxane) and an alkoxysilane, (b) optionally ... 04/13/06 - 20060078487 - Three dimensional high regular nano-porous inorganic material having fine pores and method for preparation thereof, and method for evaluation thereof A nanoporous inorganic material with high three-dimensional regularity having a large number of fine pores having a nanometer-order size in an inorganic skeleton structure, which has a pore size of 0.5 to 5 nm at a peak of a pore size distribution determined from a nitrogen adsorption isotherm, and a ... 01/26/06 - 20060018816 - Diluted magnetic semiconducting zno single crystal A new diluted magnetic semiconductor-spintronics material and method for its production are disclosed. The material can be in bulk or thin film form. The material comprises zinc oxide (ZnO) which includes a transition element or a rare earth lanthanide, or both, in an amount sufficient to change the material from ... 09/22/05 - 20050207960 - Method for producing a polycrystalline silicon, polycrystalline silicon and solar cell Silicon raw material and gallium dopant are charged and mixed in a crucible. The silicon raw material is heated to a predetermined temperature, and melted under an inactive gas atmosphere. The melted silicon raw material is cooled down to be crystallized to make a polycrystalline silicon incorporating the gallium dopant. ... ### FreshPatents.com Support |
