Ideal for semiconductor manufacturing equipment! Introducing high insulation resistance alumina.
Introducing our dense alumina, which has overwhelmingly increased the insulation breakdown voltage at high temperatures, essential for insulator parts, ahead of other companies.
Alumina ceramics, even as insulators, have inherent limits to their voltage endurance. However, the alumina ceramics N-9H and N-999S, proudly produced by Nishimura Ceramics, boast a high insulation resistance that prevents insulation breakdown even at over 6000V with a thickness of just 0.3mm. Additionally, their volume resistivity maintains high efficiency not only at room temperature but also at elevated temperatures exceeding 100°C. In high-temperature processes, the resistance of the base material has its limits, making these ceramics suitable for environments where insulation breakdown must be withstood at high temperatures, and where a higher voltage, safer, and higher purity insulator is required. Unlike regular alumina ceramics, which may have particle structures influenced by sintering aids or voids, resulting in a less dense particle arrangement, this high insulation resistance alumina ceramic features an ultra-dense particle structure that maximizes the inherent properties of alumina ceramics.

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.
