High-purity foreign fine ceramics primarily consisting of alumina-zirconia oxide systems and silicon carbide-silicon nitride non-oxide systems.
This is an introduction to overseas fine ceramics through our Chinese subsidiary. In addition to oxide-based materials such as alumina and zirconia, we have recently expanded our offerings to include non-oxide ceramics such as silicon carbide and silicon nitride. In particular, our general-purpose alumina is available in a wide range of grades, from high-purity grades suitable for semiconductor applications with a purity of over 99.5% to general-purpose grades aimed at cost reduction with a purity of 96% or lower. We can propose purity and grade options tailored to your specifications. We also handle a variety of zirconia with a wealth of experience. Regarding manufacturing methods, we employ a low-pressure injection method that minimizes mold costs, and we excel at creating three-dimensional structures that can only be reproduced through molding, making it especially suitable for cost reduction in medium to large lots. We also offer post-sintering polishing, and mirror finishes are possible. Additionally, due to high demand, we produce a significant amount of non-oxide hard materials such as silicon carbide and silicon nitride. Depending on the application and needs, we can propose various purity and grade options, so please feel free to inquire.

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.
