The word for ceramics originated from the Greek word "keramos" meaning an object of baked and hardened clay.
Ceramics date back to a type of unglazed pottery from ancient times.
Functional ceramics, which are made by baking non-ferrous materials, have been and are still manufactured in the forms of spark plugs, substrates, and insulators. These ceramics have properties such as heat resistance, corrosion resistant, and insulation. In recent years, an even wider variety of refined materials have become known as "fine ceramics".
Adamant Namiki is a World leader producer of components and products in fine ceramic.
In our company, zirconia, alumina and zirconia-toughened alumina powder is prepared according to the product, and then cast and sintereds.
We fabricate corresponding to request using forming methods that focus mainly on injection molding, extrusion molding, powder molding, and CIP molding.
Moreover, the sintering process realizes the supply of stable products through precise temperature control using an electric furnace that gives priority to cleanness. In addition, we also handle ceramic materials such as silicon nitride, silicon Hard Metal and aluminum nitride.
