Since fine ceramics are superior to metals in corrosion, heat and wear resistance, it is the key technologies for industrial progress to apply them to industrial field. While, fine ceramics have so poor toughness to fracture under stress concentration relatively easily and therefore it is difficult to utilize them to industrial products. This report shows the application examples and problems of fine ceramics applied to industrial field, mainly combustion engines and chemical plants.
