Abstract
PURPOSE: To obtain platinum paste promising in the field of electronic industry by combining the platinum powder of the specific particle size and bulk density comprising reducing and depositing platinum compound under the specific conditions with inorganic binders and metal powder and letting the same be dispersed in an inert liquid vehicle.
CONSTITUTION: Platinum compound such as chloroplatinic acid or other is reduced by using a reducing agent such as hydrazine hydrochloride or other and a buffer such as ammonium acetate under the conditions of pH 3 or over and reaction temperatures 10 to 100°C, to allow platinum powder to deposit. This platinum powder is separated from the solution and the residual salts are washed away, after which it is dried, by which nearly spherical platinum powder of particle sizes 0.1 to 7μ, bulk densities 3 to 10g/cm2 is obtained. This platinum powder is combined with suitable amounts of inorganic binder powder such as glass frit or other and powder of metals or metal compounds such as Bi2O3 or other and these are dispersed in the vehicle composed of ethyl cellulose and butyl carbitol acetate, etc. The mixture is prepared into paste. If this paste is coated on a substrate and is baked, the superior platinum film is formed.
