UTILIZATION AND WORKING OF MATERIAL OCCURRED BY IGNITION LOSS IN MELTING FURNACE, UTILIZATION AND WORKING OF MATERIAL OCCURRED BY POLISHING IN PRODUCTION OF SEMICONDUCTOR, PRODUCTION OF ANTIBACTERIAL METALLIC BINDER, WORKING FOR THE SAME, PRODUCTION OF ANTIBACTERIAL FINE POWDER, UTILIZATION OF THE SAME, WORKING AND UTILIZATION OF ABRASIVE GRAIN IMPARTING ANTIBACTERIAL PROPERTY AND WORKING AND UTILIZATION OF ANTIBACTERIAL BLASTING MATERIAL
PROBLEM TO BE SOLVED: To utilize fine powder occurred by ignition loss caused in the production of oxide ceramics such as alumina or zirconia by the repetition of melting reaction as the stock for ceramics, and extender, antibacterial ceramics, an antibacterial metallic binder, etc., as it is or optionally after mixing with an antibacterial metal, etc. ;SOLUTION: The particle diameter of the fine powder occurred by ignition loss is 0.005-7 m. Fine powder by the reduction and melting of alumina, zirconia or silicon carbide is a high quality material as stock for ceramics. The antibacterial metal such as Ag, Cu, Sn or Zn is used in an ionic state by dissolution in nitric acid, acetic acid, etc. In the case of use as a binder, e.g. an alumina or silica sol is used. An antibacterial metallic binder may be prepd. by adding a soln. of the antibacterial metal in nitric acid to a metallic binder. Utilization as an abrasive material such as a blasting material or abrasive grins is also enabled.;COPYRIGHT: (C)1999,JPO
