ABSTRACT:
A novel aluminum nitride material having a low room temperature volume resistivity is provided. The aluminum nitride material has an aluminum nitride main component and includes at least 0.03 mol % of europium oxide. The aluminum nitride material has an aluminum nitride phase and an europium-aluminum composite oxide phase. An aluminum nitride material also provided having an aluminum nitride main component, wherein a total content of europium oxide and samarium oxide is at least 0.09 mol %. The aluminum nitride material has an aluminum nitride phase and a composite oxide phase containing at least europium and aluminum.
