We develop fine ceramic products which are widely used in machinery, semiconductor, aerospace,
petroleum, chemical, electronics, medical, fluid control, food and
other industries. The superior electrical characteristics of fine ceramics are utilized in a variety of circuit boards and electronic parts.
Their wear and corrosion resistance is beneficial in pumps nozzles
and valve parts, and their high heat and thermal shock resistance
is useful in ceramic engine parts.
