Fine Ceramics

The Fine Ceramics industry!In a rapidly changing industrial structure and living environment it has a limitness potential and its applications are varied and many in a wide range of fields. These properties include the ability to withstand heat, the ability to withstand corrosion resistance to wear and a high degree of electrical insulation. 

DONGKUK CERAMICS have been putting considerable R & D effort into meeting the ever-diversifying needs. Upgrading the performance and reliability of its ceramics by employing new techniques allied with existing skills to utilize to the full, the properties of Fine Ceramics.
