UBE Raises Prices of High-Purity Silicon Nitride Powder by 30 Percent

UBE Corporation has officially announced a thirty percent price increase for its high-purity silicon nitride powder, effective across current reference levels. Despite ongoing internal efforts by the company to optimize production yields, stabilize supply chain resilience, and reduce operational costs, escalating facility maintenance expenses and rising labor costs have made it unsustainable to absorb these inflationary pressures through self-help measures alone.

High-purity silicon nitride is a vital advanced material in modern engineering and clean technology applications. It plays an essential role in manufacturing high-performance ceramic bearings for electric vehicle motors, as well as high-thermal-conductivity insulating substrates for power semiconductor modules. As the global shift toward electric mobility and wide-bandgap power electronics accelerates, silicon nitride remains indispensable due to its superior mechanical strength, thermal shock resistance, and electrical insulation performance. With UBE maintaining a substantial global market share in this specialized material sector, this price adjustment highlights the growing structural cost challenges facing critical supply chains across the advanced manufacturing landscape.
