Abstract: Disclosed is an antibacterial product including at least one antibacterial part, wherein the antibacterial part includes a surface layer containing silver sintered under a nitrogen atmosphere or silver oxide sintered under an oxygen atmosphere. The antibacterial product prevents the proliferation of bacteria arising due to use thereof, kills bacteria, sterilizes and purifies contaminated water, and exhibits an antibacterial effect against harmful bacteria within at most 6 hr, and preferably an early antibacterial effect within 3 hr, especially 2 hr.

Abstract: Disclosed is a water-preserving container including a first silver nitride (Ag3N) sintered-surface layer on a portion of an inner wall or the entire inner wall of the water-preserving container, and a second silver nitride sintered-surface layer on a portion of a lip contact part or the entire lip contact part of the water-preserving container. The water-preserving container prevents the proliferation of bacteria generated according to use and destroys the bacteria, sterilizes and purifies polluted water, and exhibits an early antibacterial effect within 2 hours.

Abstract: A blade made of a carbon steel or alloy steel is subjected to a surface nitriding process to form a high hardness nitride layer having a thickness in the range of 10 ?m to 100 ?m and a Vickers hardness Hv of 1000 or more, and a silver oxide layer, a copper oxide layer, or a silver oxide and copper oxide layer is formed on the high hardness nitride layer of the blade by firing. Through this processing, the blade that has a high cutting maintaining ability and an excellent sanitization ability such as antibiosis, sterilization ability, and antimold ability is provided.
