Tateho
Japanese expert in high-purity magnesia products.
Tateho Chemical Industries Co., Ltd. is an established chemical and materials engineering company with roots in the traditional salt production of Japan's Ako region. The company's industrial journey began in 1948 by repurposing bittern—a byproduct of salt production—to synthesize high-purity magnesium oxide (MgO). Gaining independent corporate status in 1966, Tateho has spent decades specializing in inorganic powder synthesis and precise particle control. Having secured ISO 9001 and ISO 14001 quality certifications over the years, the company joined the industrial gas and logistics corporation Air Water Inc. in 2006. Today, it operates a global supply chain network with facilities across Asia, North America, and Europe.
Advanced Particle Size and Shape Control
By combining different production methodologies such as liquid crystallization precipitation and electric arc furnace melting, Tateho has the flexibility to synthesize powders in the exact size and morphology (cubic, rod-like, octahedral, etc.) required by customer specifications.
Raw Material Independence and Batch-to-Batch Consistency
The high-purity magnesium oxide powders are synthesized directly from the company's own resources. This integrated structure minimizes microscopic contaminations, batch-to-batch quality deviations, and price fluctuations that can occur with third-party suppliers.
Analytical Traceability and Quality Control
The company's laboratory infrastructure (equipped with XRF, ICP, XRD, FE-SEM, etc.) is capable of detecting parts-per-million (ppm) level impurities, which is critical for the electronics market. Every raw material produced is audited under ISO standards and offers 100% backward traceability.
Reliable Global Supply Chain
The company's manufacturing facilities spread across Asia, North America, and Europe, combined with the robust logistical infrastructure of its parent company Air Water Inc., ensure an uninterrupted and secure supply of industrial raw materials against geopolitical risks and regional shipping bottlenecks.
Tateho focuses on the synthesis of functional additives and inorganic powders critical for high-tech industries:
Electronics & Semiconductors (MLCC): Production of high-purity magnesium oxide powders, strictly stripped of trace impurities (Fe, Si, Al, Ca), which optimize sintering behavior and stabilize dielectric properties for Multilayer Ceramic Capacitors.
Heavy Industry & Electromagnetic Infrastructure: Provision of industrial raw materials for high-temperature refractories in the steel industry, and precisely sized powder formulations for coating electromagnetic steel sheets in power transformers.
Eco-Friendly Safety Technologies: Development of halogen-free, environmentally compliant magnesium hydroxide-based flame retardant powders for electronic circuit boards and wiring.
