Ceramic Cylinder for Vacuum Circuit Interrupter

These ceramic (alumina 92 - 95%) provide superior electrical insulation, hermeticity, mechanical strength, heat resistance, and can accommodate high-temperature exhaust. They also excel in dielectric strength and are available in a wide range of sizes.

Ceramic Heater

Using an alumina ceramic body in which a heating element is buried then sintered onto the unit, these ceramic heaters can be made lightweight. In addition they excel in chemical resistance and in uniform temperature distribution.

Ceramic Seal Ring/Disk

Seal rings/disks seal in the liquids that are found in rotational or sliding portions. Taking advantage of the material's resistance to wear, corrosion, and heat, the seal rings/disks are used in areas such as mechanical seals for automobile, electromagnetic valves, and wear faucets.

Electrically Conductive Zirconia

NTK Electrically Conductive Zirconia, "KGS-20" is one of the best materials for Wear-Resistance application, especially, Stamping Punch, Punch Tooling, Die Plate and Guide Roller. It allows to be machined by EDM (Electrical Discharge Machining.)

Heat Resistant Ceramic

The material's heat resistance property is utilized to make welding nozzles, casting gate nozzles and the other product lines which are required high temperature resistance and also heat shock. The custom design is available.

Oxygen Sensor

Highly suited for Oxygen Concentrator, PSA, Air Monitoring, and Industrial Process Control applications.

Silicon Nitride Ball Bearing

Silicon Nitride features properties such as the ability to reduce the generation of heat associated with centrifugal force and reduced friction coefficient and high rigidity. Both blank and finished ball are available.

Silicon Rectifier Container

This item is available in power semiconductor packages (diode, thyrister package, etc) that can accomodate all stud and flat types.

Terminal

Taking advantage of the superior electrical insulation and mechanical strength properties of Alumina Ceramic, NTK manufactures a variety of terminal products such as terminal connector boards and ceramic feed-through.
