Outline of Final Research Achievements

We have successfully developed a novel antiviral powder material consisting of calcium oxide and small amounts of alumina or zirconia as a second phase. The composite powders were synthesized by mechanical alloying (MA). The effects of alumina or zirconia addition and MA conditions on antiviral activities of calcium oxide have been investigated against H5N3 avian influenza virus. The incorporation of small amounts of alumina or zirconia significantly improved the durability of antiviral activities of MAed and hydrated calcium oxide. The reasons for improvement of durability of antiviral activities seem to be attributed to the solid solution of alumina or zirconia into calcium oxide and agglomeration of the powders during the mechanical alloying.
