About This Product

■Conductive diamond expands the possibilities of electrochemistryDiamonds never cease to fascinate people. Its appeal lies not only in its beauty, but also in the manufacturing field due to its versatile and unique properties such as high hardness, refractive index, and thermal conductivity.

Diamond is composed of carbon, and it has become possible to synthesize diamond from gas containing carbon atoms. Synthetic diamonds have expanded the range of uses for diamonds, such as their cost advantage and the ability to add properties tailored to the application.

Furthermore, by doping diamond, which is an excellent insulator, with boron, it became possible to conduct electricity, and a technology was established that allowed diamond to be used as an electrode.

■Wide potential windowPriority can be given to oxidation and reduction reactions of substances that are normally difficult to electrolyze, and it is possible to decompose and synthesize substances that are difficult with conventional methods. Therefore, it is possible to generate ozone by directly electrolyzing water, and it is also possible to reduce water pollution indicators such as BOD and COD of waste liquid.

■Physical and chemical stabilityIt is a highly hard and highly corrosion-resistant material that can be used stably for long periods of time even in heavily soiled environments, strong acids, strong alkalis, and organic solvents. Therefore, it can be used as an electrode even in strong acids such as sulfuric acid, and it is possible to dramatically extend the lifespan of electrolytic treatment electrodes that used to use rare metals.

■Small background currentDue to its high signal/noise ratio, it can be used as a highly sensitive sensor in electrochemical analysis. Therefore, it is possible to create ultra-sensitive magnetic and electric field sensors called quantum sensors. This quantum sensor can function in various environments including room temperature, normal pressure, and the atmosphere.

■Strengths・Stable film-forming technology that enables mass production of large-area diamonds
・Durability due to thick and uniform film thickness
・High conductivity and imparting conductivity according to the application

■Application fieldTaking advantage of its unique properties, diamond is expected to be applied in a wide range of fields, and the need for diamond in the manufacturing field is expected to increase rapidly.
・Processing of various solutions and waste liquids by component decomposition
・Alternative technologies for manufacturing processes such as ozonated water and electrolyzed sulfuric acid generation
・Realization of green technology without waste
・Medical application as a highly sensitive electrochemical sensor
・Drug discovery using organic electrolysis
