摘要：
Cemented carbide articles produced by tape casting a slurry of ingredients including organic resins and plasticizers, forming the cast tape into a desired shape and firing the tape, are improved by eliminating carbonaceous residue-forming ingredients from the organic portion of the slurry, resulting in reduced porosity of the fired article.
