GS Series granules are produced from AlN020SS, our highest-purity aluminum nitride powder.
A controlled granulation process combines the powder with a binder and sintering aid, giving each granule a consistent, flowable structure.
The sharp particle size distribution and high fluidity make GS Series a reliable choice for compression and molding of AlN ceramics.
Key applications
GS Series granules are used to produce thermally conductive AlN ceramic substrates and ceramic parts. Circuit carriers and heat sinks for semiconductors and high-power electronics are the most common end uses.
