Mingrui Ceramics is an expert at manufacturing & supplying technical ceramic products to be used in the most demanding thermal, electrical, and mechanical conditions. Our ceramics have been used as electrical insulators in a variety of applications where high voltages and high temperatures cause other materials to fail. There are types of ceramic materials that offer excellent thermal conductivity which are commonly used in electronics applications where electrical insulation and heat dissipation are required. Many ceramic insulators undergo special processes like glazing, coating, or metalizing which opens more opportunities for practical application of technical ceramics.
