Research & Development

Creating new global standards with an eye on the future and the world.

NGK's research and development activities focus on materials development and system technologies related to ceramics technologies.
In the Triple E domains of energy, ecology, and electronics, our experts across a wide range of fields work day and night to develop new technologies and new products. These technologies and products seed new businesses in areas from basic research on ceramics to applied research.

Creating new products

Examples of new product initiatives include a new Ceramic Battery Project in fiscal 2016 and an Optical Component Project in fiscal 2017.
In both projects, the Corporate Manufacturing Engineering, Corporate R&D, relevant business departments, and head-office sections work together to establish new businesses through product development, development of mass-production equipment, and customer development efforts.

Optical Component Project

The Optical Component Project was established in April 2017 as a companywide cross-functional organization intended to develop new electronics businesses.

Gallium nitride (GaN) wafers


Our proprietary crystal growth technologies achieve vanishingly low levels of flaws across the entire wafer surface. Using our wafers in circuit boards makes it possible to realize ultra-high-luminance lasers and light-emitting diodes (LEDs) unlike no device seen before.

Examples of final use

These technologies are expected to make their way to applications like projectors and stadium lighting, where lasers and LEDs have yet to enter widespread use because they lacked sufficient light intensity.

Microlenses for ultraviolet LEDs


NGK has applied its proprietary molding technologies and calcination techniques to create high-quality transparent quartz glass lenses of complex shapes that make efficient use of ultraviolet LEDs.

Examples of final use

Mercury lamps currently serve as the source of the ultraviolet (UV) light commonly used in applications like hardening resins, sterilization, and cleaning. With prospects of an impending ban on the use of mercury from 2020 due to the Minamata Convention on Mercury, ultraviolet LEDs that do not require mercury have drawn growing attention.

Ceramic Battery Project

In April 2016, the Corporate Manufacturing Engineering, Corporate R&D, relevant business departments, and head-office sections joined forces to establish the Ceramic Battery Project. Companywide efforts are underway to rapidly bring new products to market.

Chip-type ceramic secondary batteries

  • Crystallographically oriented ceramic positive electrode plate (basic patented)
  • Ultrathin, high energy density, resistance to high temperatures
Examples of final use
  • Wearable devices
  • Smart cards
  • IoT modules
  • Onboard microcomputer power supplies

Zinc secondary batteries

  • Ceramic separators made using new materials
  • Water-based electrolytic solution (for safety), high capacity, constant temperature operation
Examples of final use
  • Residential power storage systems (10 kWh class)
  • Indoor-type power storage systems (500 kWh class)Office buildings, hospitals, retail facilities, etc.

Solid oxide fuel cell (SOFC) modules

  • Proprietary structure and ceramic materials
  • Compact, high power generation efficiency, high durability
Examples of final use
  • Single-family home and condominium use (installed in each unit)
  • Fuel-cell systems
