Product Introduction

NANOCERAMTM is glass-ceramic for which we have further evolved OHARA’s nanocrystallization technology, thus far recognized in all fields, and achieved superior mechanical properties and high transmittance.
New proposals will be possible that cannot be realized with sapphire crystal glass and chemically strengthened glass, such as cover glass for optical devices and mobile devices, which requires shock resistance.

Feature

  • 01Impact Resistance High Hardness

    Compared with general borosilicate glass, NANOCERAM™ has 30% higher hardness and showed more than 10 times higher impact resistance in steel ball drop impact test. In addition, it has a 20% higher hardness than chemically strengthened glass, and showed more than 3 times higher impact resistance in steel ball drop impact test. Also, it has better fracture toughness than sapphire crystal glass, and cracks that cause breakage do not occur even if there are scratches and realizing a characteristic that is resistant to cracking.

  • 02Good Processability

    Although it has the properties of hard ceramics, the cutting, polishing and moldability realized workability comparable to that of glass. Moreover, it has grinding and polishing property which can shorten process time to about 1 / 20th of sapphire crystal glass.

  • 03High Transmittance

    Since, crystal grains of glass ceramics are large, so it is difficult to transmit light and never used for optical applications. However, high transparency has been realized by Ohara's nanocrystallization technology (particle diameter about 6 nm) which has a high track record in the space and astronomy fields. NANOCERAM™ is mounted on a high-end lens protector for single-lens reflex interchangeable lenses of domestic manufacturers who are demanding strict optical performance and precise quality, and NANOCERAM™ has received high marks.
