METAL PARTICLE POWDER AND PASTE COMPOSITION USING SAME |
摘要 |
<p>It is important that the metal particles used in a conductive paste used for wiring have the characteristic of being easily dispersed in a polar solvent in combination with another material such as a resin used in a paste. Provided is a metal particle powder which exhibits a pH value of 6 or less when 0.5 g of the metal particles to be evaluated are added to 100 mL of a potassium hydroxide solution with a pH of 11, and then an aqueous nitric acid solution in an amount in which pH becomes 5 by adding 0.10 mol/L nitric acid to 100 mL of a potassium hydroxide solution and 10 mL of ethyl alcohol (blank solution) with a pH of 11 is added.</p> |
