NGK Insulators: Pioneering Ceramics for a Sustainable Future
Founded in 1919, NGK Insulators, Ltd. (NGK) has evolved into a global leader in ceramics technology, addressing critical societal challenges across mobility, energy, IT, and industry. With operations in over 15 countries, the company is dedicated to innovation and sustainability, exemplified by its commitment to carbon neutrality and digital transformation through its “NGK Group Vision Road to 2050.”
Core Technologies and Product Portfolio
NGK’s expertise lies in proprietary core ceramic technologies, which underpin a diverse product portfolio. The company is a major manufacturer of ceramic substrates for automotive catalytic converters, playing a vital role in reducing vehicle emissions. Beyond automotive applications, NGK is too making significant strides in energy storage and semiconductor materials.
Reducing Emissions with HONEYCERAM®
A cornerstone of NGK’s environmental efforts is HONEYCERAM®, a ceramic catalyst carrier used in automotive exhaust systems. This innovative product neutralizes harmful substances in exhaust gases through its unique honeycomb structure, maximizing surface area for efficient purification within a compact space. The honeycomb design provides a surface area equivalent to two soccer fields within a palm-sized unit, even as its thin walls (0.05 mm) minimize engine power loss. Learn more about HONEYCERAM®. Large-size HONEYCERAM® (LSH) models are specifically designed for large diesel vehicles and equipment, removing particulate matter (PM) and nitrogen oxide (NOx) from exhaust emissions. Explore HONEYCERAM® applications.
Advancing Energy Storage with EnerCera
NGK is also at the forefront of energy storage technology with its “EnerCera” series of compact, thin, and high-energy-density lithium-ion rechargeable batteries. These batteries are crucial for building sustainable energy infrastructure. Discover EnerCera battery technology. Recently, EnerCera batteries supported a demonstration experiment of Tohoku University’s tsunami balloon project. Read about the Tohoku University project.
Innovating Semiconductor Manufacturing
Recognizing the growing importance of semiconductors, NGK has developed the Translucent Alumina Wafer, a key component for chiplet integration processes. This material is gaining recognition as an indispensable element in advanced semiconductor manufacturing. Learn about NGK’s semiconductor solutions.
Commitment to Sustainability and Environmental Responsibility
NGK’s dedication to sustainability is further demonstrated through its recognition as an “Eco-First Company” by Japan’s Ministry of the Environment and its “A List” rating in CDP Water Security for two consecutive years. Explore NGK’s sustainability initiatives. The company also collaborates with partners like Chubu Electric Power to research ammonia-burning kilns and has launched a global campaign with CNN showcasing innovation for a sustainable future. Read about the CNN partnership.
Recent Developments
In March 2026, NGK announced that a leader driving its EnerCera battery business was named a finalist for the Women Leaders in Electronics Awards 2026. Read the press release. The company also successfully established mass production technology for products using hydrogen combustion. Learn about hydrogen combustion technology.
NGK continues to invest in research and development, aiming to provide innovative, high-quality products that contribute to a society where people can coexist with nature while supporting essential social infrastructure.
