Alumina (AI₂, O₃)

It is the most commonly used ceramic and is mainly used in semiconductor and LCD parts, plasma parts, and various jigs and rings because it has excellent mechanical strength, heat resistance, and corrosion resistance.

Zirconia (ZrO₂)

It has the highest hardness after diamond, so it has very strong mechanical strength, excellent wear resistance, heat resistance, and impact resistance, and very good surface gloss after processing. It is used for various cutters, guide rollers, various jigs, precision bearing balls, precision pump seals and valves.

Silicon Nitrode (Si₃N₄)

It has excellent characteristics at room temperature and high temperature, and is used in heat exchangers, reaction tubes, bearing balls and roller cutting tools, wear-resistant parts and rotating shafts of the engine.

Silicon Carbide (SiC)

It has high covalent bonding and hardness than alumina. In particular, due to its excellent high-temperature strength, it is widely used as a high-temperature structure such as hita materials, gas liners, turbine components, semiconductors and LCD components.

Other Materials

Recently, as the demand for ceramics increases, the demand for ceramics, graphite, silicon, and sodium oxide having various characteristics is also increasing. These materials are not included in our major business areas, but like other non-ceramic materials, they can be supplied according to customer requests.
