Sterilizing agents, their method of manufacture and uses

Abstract

The sterilizing and deodorizing agents target bacteria, odors, toxic substances, etc. and are made from silver as metal particles and titanium dioxide as ceramic particles by (1) thermal bonding or (2) pressure bonding or (3) thermal/pressure bonding and mixing the resultant with hydroxyapatite as an adsorptive material. The agent can be mixed with ink, bonding agents and paints and applied to a variety of substrates.

1 . An element comprising:
 metal particles selected from the group consisting of gold, silver, platinum, copper and combinations thereof; and   ceramic particles comprising titanium dioxide,   wherein the metal particles and the ceramic particles are bonded together, and one of at least a part of one of the metal particles or at least a part of one of the ceramic particles is ingrown into the other,   wherein the metal particle is ingrown into the ceramic particle by pressure bonding or a combination of pressure bonding and thermal bonding.   
     
     
         2 . The element according to  claim 1 , wherein the element has an effect without a presence of light which is a same effect as the element has under light. 
     
     
         3 . The element according to  claim 1 , wherein a weight ratio of the metal particles is 0.1-10% of the total weight, and a weight ratio of the ceramic particles is 90-99.9% of the total weight. 
     
     
         4 . The element according to  claim 2 , wherein the effect comprises at least one of sterilizing effect, an effect of decomposing bacteria, viruses, allergens, and fungus, odor substances and toxic substances. 
     
     
         5 . An agent comprising the element according to  claim 1 . 
     
     
         6 . The element according to  claim 3 , wherein the element has the effect when light is irradiated to the element.
