千葉セラミック工業 List of Products and Services

We would like to introduce our product, "Reinforced Alumina ZTA-30." This material is made by adding zirconia to alumina and sintering it densely. It is suitable for areas that would wear out with regular alumina and for parts that require toughness. It has high mechanical strength, thermal conductivity, and fracture toughness, making it particularly suitable for mass-produced items made from processed products and molds, especially for impact-resistant and wear-resistant components. 【Features】 - High mechanical strength, thermal conductivity, and fracture toughness - Suitable for mass-produced items made from processed products and molds, particularly for impact-resistant and wear-resistant components * A comparison table of bending strength, Vickers hardness, etc. is included. * For more details, please refer to the related links or feel free to contact us.

Sapphire, which is also famous as a gemstone, has high transparency across optical properties from ultraviolet rays to visible light and infrared rays. It is often processed into transparent plates to be used as "windows," "glass," or "crystal" in high-end wristwatches. Additionally, it is used in optical components such as sensors and instruments. 【Features】 ■ High Transparency: It can be used for optical windows that utilize infrared rays, as it transmits not only visible light but also infrared rays. ■ Excellent Strength: With a Vickers hardness of 22.5 GPa and a bending strength of 690 MPa, it maintains strength even when processed thinly. ■ High Thermal Conductivity: There are few transparent materials that conduct and dissipate heat effectively. ■ High Heat Resistance: Since sapphire rough stones can only be created at ultra-high temperatures exceeding 2,000°C, it is a material that can withstand high-temperature use. ■ High Corrosion Resistance: It is almost insoluble in acids and alkalis, making it chemically stable. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case of manufacturing ceramic-shaped products using supplied raw materials. We received a request from a customer asking us to mold and sinter products using their developed raw materials. We conducted tests to select a binder and determine spray conditions using a small amount (1-2 kg) of raw materials, repeatedly testing molding and sintering to establish optimal conditions, and then carried out prototype production. After receiving approval from the customer on the prototype, we proceeded to mass production following a mass production trial.

We would like to introduce a case of producing color ceramics. When we requested a competitor to manufacture color ceramic products, they declined, citing concerns that it could cause contamination with other mass-produced items. As a result, we received a request from a customer asking if we could handle it. Using specialized equipment held by our development department, we formulated the raw materials and created prototypes (color matching and other characteristics). After receiving approval from the customer on the prototypes, we established a dedicated manufacturing line using different equipment to prevent contamination with other mass-produced items during the manufacturing process. Using this manufacturing line, we mixed, shaped, and fired the products for delivery. [Customer Request] ■ We would like you to handle this as a competitor declined our request, stating it could cause contamination with other mass-produced items. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case of developing a high dielectric constant single-layer capacitor. We received requests from customers such as, "We would like you to develop a new single-layer capacitor with ε○○" and "The temperature characteristics should be within the standard of ±○○%." We repeatedly formulated the mixture in small test batches (1-2 kg per batch) until we achieved the desired ε, conducting confirmation tests to discover the optimal values. After receiving approval from the customer based on those results, we conducted reproducibility tests and mass production tests. Since the mass production tests were completed without any issues, we proceeded with mass production and delivered the product. [Customer Requests] ■ We would like you to develop a new single-layer capacitor with ε○○. ■ The temperature characteristics should be within the standard of ±○○%. *For more details, please download the PDF or feel free to contact us.

"Zirconia" is a type of ceramic that has very high strength and toughness at room temperature. As the temperature increases from room temperature to high temperature, the crystal system changes. When yttrium and other elements are added and heated, the high-temperature phase stabilizes at room temperature, forming a cubic or tetragonal solid solution. Due to its high sliding properties, it is used as a sliding component in pump parts, and its wear resistance and high toughness contribute to its use in industrial cutters, knives, and decorative parts, leading to a longer lifespan. [Features] - Partially stabilized zirconia is widely known as a high-strength, high-toughness material, used in cutting tools and grinding components. - In recent years, its applications have expanded to include optical fiber components, biomaterials, and jewelry. *For more details, please download the PDF or feel free to contact us.
