Nanoceram – Manufacturer & Supplier

NANOCERAM? is a new glass ceremic material feraturing extremely high strength, high transmittance, and excellent machinability.

It is a further evolution of OHARA's crystallized glass, which has been highly regarded in space, astronomy and a wide variety of other fields.

With NANOCERAM?　we propose new value for applications in optical instruments and cover glass for mobile devices, which require strength that cannot be achieved with sapphire crystal glass or chemically strengthened glass.

Compared with general borosilicate glass, NANOCERAM? has 30% higher hardness and showed more than 10 times higher impact resistance in steel ball drop impact tests.

In addition, it has 20% higher hardness than highly strong chemically strengthened glass and showed more than 3 times higher impact resistance in steel ball drop impact tests.

Also, as NANOCERAM? has better fracture toughness than sapphire crystal glass and features strong resistance to cracking, scratches will not lead to cracks that cause breakage.

Conventional glass ceramics had large crystal grains, making it difficult to transmit light, so they were never used for optical applications. However, with the realization of high transparency using OHARA'S Nano crystallization technology (particle diameter of about 6mm), which has a strong track record in the space and astronomy fields, NANOCERAM? is mounted on high-end protectors for single lens reflex interchangeable lenses of domestic manufacturers who demand strict optical performance and precise quality and has received strong praise.
