Increase in firing efficiency (more shelves) Electricity costs are rising, and I want to fire more products at once. Is it possible to increase the number of shelves (levels) even more? If you have such requests, please feel free to consult with us.

Micro protrusions present, firing setter, high-temperature resistant ceramic ■ After firing, it sticks to the setter ■ The vacuum furnace piping gets clogged ■ Although powder is spread to prevent sticking, cleaning is very difficult For those facing such issues, please try our setter once. With its micro protrusions, it is designed to prevent sticking, so please consider it.

Zirconia has various applications. ■Applications Machine parts Ceramic cutting tools Connector parts for optical communication Oxygen gas sensors Thin sheets for electronic components Electrolyte sheets for fuel cells If you have any requests regarding size, thickness, etc., we look forward to hearing from you.

Alumina substrate Alumina substrates are in demand as general-purpose items, and we have received many inquiries about them. If you have any concerns, requests for larger sizes, or specifications you are interested in, we look forward to hearing from you.

In recent years, the development of tiny chip components that can now fit on the tip of a finger has been advancing the information society in the rapidly evolving electronics industry. Among these, chip resistors are essential basic electronic components that make up electronic circuits. Our alumina ceramics use high-purity alumina raw materials with excellent electrical and thermal properties, and through advanced processing technology, we achieve outstanding dimensional accuracy and divisibility. For other alumina ceramic products as well, we use high-purity alumina raw materials suited to their applications, maintaining stable quality and excellent characteristics while producing under a strict quality control system.
