A material that has high mechanical strength at room temperature! High toughness fine ceramics!
Zirconia (ZrO2) is a ceramic with excellent mechanical strength and wear resistance. As a fine ceramic, zirconia is a difficult material to machine, but our company can accommodate various shapes through precision and fine processing. We also offer various types such as partially stabilized zirconia, stabilized zirconia, and conductive zirconia, as well as black zirconia. Due to its unstable crystal structure, zirconia has limited use at high temperatures. Therefore, we also handle zirconia suitable for specific applications, such as stabilized zirconia with added Y2O3. [Features] - Among fine ceramics, it has the highest toughness, making it less prone to cracking and chipping. - Its high thermal expansion rate is close to that of metals, allowing for consideration of combined use. - Its low thermal conductivity provides expected insulation effects. - The crystal structure changes with temperature fluctuations, making it unstable and prone to degradation. - Its high temperature and high fracture toughness are 3 to 4 times that of conventional ceramics. - It excels in insulation effects. [Examples of Applications] - Insulation blocks, guide spacers, grinding balls, nozzles, etc. - Fitting parts with metals, pump components, reaction tubes, etc. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Narasaki Sangyo Co., Ltd. "Functional Materials Division" specializes in high-performance material contract processing. The materials we handle fall into "five categories": 1. Ceramics/Glass 2. Metals 3. Engineering Plastics 4. Carbon 5. Surface Treatment We offer a wide range of services, and if you provide us with a single production drawing, we can deliver various materials and surface treatments as a one-stop solution. We cater to everything from general-purpose to specialty materials, including high-precision, fine, electrical discharge, laser processing, as well as surface treatments such as coating, precision cleaning, and blasting. Our particular strength lies in high-precision and short-lead-time processing of ceramics. By machining from pre-fired materials, we achieve short lead times for ceramics that traditionally take several months. We handle a wide range of ceramics, including machinable ceramics like Hotovel, as well as fine ceramics such as alumina and zirconia, and non-oxide ceramics like silicon carbide, silicon nitride, and aluminum nitride. We are also actively engaged in proposing cost reductions for overseas ceramics and other international materials. We can accommodate various contract processing projects, from prototype development starting with a quantity of one to mass production.
