This product possesses many strongpoints,including high purity,small particle diameter,equabiy separate,large specific surface area,high surface activity and low loose loading density. When it's used in film-plating and device production this material can effectively improve the hardness,melting point,and chemical stability of the products.Otherwise,this material have excellent electric conductance,so it can be used to make electrode andelectric contact.Because of its obvious advantages,the powder also can replace the micron-TiN powder.
