大塚セラミックス List of Products and Services

This is an insulating ceramic characterized by being lightweight and having a low thermal expansion rate, excelling in thermal shock resistance. It exhibits less than half the thermal expansion rate compared to common materials like alumina. It is used in applications where dimensional changes due to temperature fluctuations must be minimized, or as insulating materials that experience rapid temperature changes. Our company conducts consistent manufacturing from material procurement to production at our raw material factory. We respond to requests such as "The machine parts currently in use have been discontinued and cannot be procured" and "I want it made in shapes, strengths, and specifications that are not available in existing products." Examples of applications: ■ Automotive parts ■ Fuse cases ■ Automotive catalysts

At Otsuka Ceramics, we manufacture "ceramic standard products" such as hex bolts and pan screws that do not undergo characteristic changes for a semi-permanent period. In addition to having high insulation properties, they can be used at ultra-high temperatures of up to 1300°C. Since they are processed before sintering, they can be produced at a lower cost than all-cut products. 【Features】 ■ High insulation properties ■ Usable at ultra-high temperatures (1300°C) ■ High acid resistance ■ Excellent chemical resistance ■ More affordable than all-cut products *For more details, please refer to the PDF document or feel free to contact us.
