Semiconductor Wafer Inc. ( SWI ) provides ZrO2 ( zirconia ) ceramic substrate . ZrO2 substrate is one of the most popular ceramic substrate which has excellent heat resistance, high mechnical strength , abrasion resistance and small dielectric loss . The surface of ZrO2 substrate is quite smooth and low porosity . Compared to alumina substrate , ZrO2 substrate has higher mechanical strength and fracture toughness , it's about three times higher for bending strength, two times for fracture toughness than alumina substrate . ZrO2 substrate ( zirconia ) also provides good abrasion resistance. It features a thermal expansion rate close to metals . SWI provides ZrO2 ceramic substrates for a wide range of applications, including thin film and thick film microelectronic , high power and high frequency circuit RF / microwave components and capacitor or resistor , contact us for more ceramic wafer product information .
