共立マテリアル Company Overview

We have high-purity silica, alumina, and cordierite suitable for semiconductor-related materials and fillers.

Our company is a retailer with manufacturing capabilities. We leverage our strengths as a raw material manufacturer to provide not only supplier analysis values but also EC measurement, dielectric constant, chemical analysis, and particle size measurement. We respond appropriately to each request. ■ High Purity Silica We handle high purity silica suitable for use in fields such as glass, optics, and electronic materials. We offer various grades with different purity and particle sizes. ■ Alumina Alumina is a representative oxide material used in a wide range of applications, including structural components, heat dissipation fillers, and glass raw materials. We offer submicron easily sinterable alumina, pre-sintered alumina with excellent flowability and processability, spherical alumina, and high whiteness aluminum hydroxide suitable for artificial marble. ■ Cordierite Cordierite is excellent in heat resistance and thermal shock resistance, used in automotive catalyst carriers and refractory materials. Due to its low thermal expansion rate and good dielectric properties, it is also gaining attention for electronic and semiconductor applications.
