SiC = Silicon carbide refractory (recrystallized, silicon-impregnated silicon carbide)
Recrystallized silicon carbide using high-purity SiC raw materials. It will ensure cost reduction.
Oxide-bonded SiC (silicon carbide) has a thermal conductivity that is more than twice that of silicon carbide, and its strength is more than five times greater, maintaining stable strength from room temperature up to 1600°C. This is high-performance SiC, specifically silicon carbide refractory. - Recrystallized SiC "R-SiC" Recrystallized SiC is formed by sintering silicon carbide particles at temperatures above 2000°C. It has a purity of 99%, making it highly pure and particularly suitable for firing processes that are sensitive to impurities. Its maximum operating temperature is extremely high at 1650°C. - Silicon-impregnated SiC "Si-SiC" Silicon-impregnated SiC is a dense material that fills the pores between silicon carbide particles with silicon, reducing the porosity to nearly zero. It has extremely high thermal conductivity and strength, maintaining stable strength up to 1350°C. It is used in beams, rollers, nozzles, and other applications. As a refractory material under high temperatures, SiC (silicon carbide) maintains its strength sufficiently compared to concerns about strength degradation with conventional cordierite and alumina. It is also optimal for firing heavy objects and for environments that require high purity, such as electronic devices and electrode materials that are sensitive to impurities.

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.
