マルワイ矢野製陶所 Company Profile

We manufacture BN (boron nitride) products with a short lead time.

BN (boron nitride) is a ceramic with excellent lubricating properties, high thermal conductivity, thermal shock resistance, low thermal expansion, and chemical stability. It has many similarities to graphite and is also referred to as white graphite. While graphite is dielectric, BN possesses high electrical insulation properties. It is used in applications such as fixtures for glass manufacturing, crucibles for metal melting, injection nozzles, electrical insulation components, and semiconductor manufacturing components. Additionally, BN-AlN, which is blended with AlN to enhance hot strength, can also be produced.

Pre-sintering processing is also possible! We have a proven track record in a variety of ceramic processing, including alumina, zirconia, and 99.8% high-purity fused silica molded products.

Our company offers "ceramics contract processing," where we handle molding, processing, and firing in-house. We can process various ceramics such as alumina, zirconia, and magnesia. In addition to post-firing processing, we also perform pre-firing processing, which helps prevent cracking and chipping due to thermal expansion and post-molding processing. Currently, we are offering a comprehensive catalog of ceramic products! It includes a wide range of ceramic products, starting from dense products like alumina and zirconia to 99.8% high-purity fused silica molded items. Furthermore, the catalog provides information on the types of ceramics, purity, and characteristics based on molding methods, making it useful for property comparison and selection! 【Points for Choosing Maruwai】 ◆ All contract molding, processing, and firing are handled in-house ◆ High purity with excellent heat resistance and thermal shock resistance ◆ Superior durability ◆ Capable of accommodating various shapes from large to small ◆ Wide-ranging support for pressing, CIP, casting, extrusion molding, and machining ◆ We also develop raw materials in-house, allowing us to propose suitable materials based on applications and needs *Please view the Maruwai Ceramics Comprehensive Catalog PDF available for download.
