    摘要: Carbon or a substance generating a carbon by thermal decomposition is added to prepared material containing aluminum nitride (AlN), an Si source such as silicon nitride (Si3N4) or a silicon oxide (SiO2), and an Eu source such as europium oxide (Eu2O3) or europium nitrate or europium acetate, and the prepared material is reduced in a nitrogen atmosphere, and subsequently fired. SiO2 is capable of converting into silicon nitride by reduction nitriding. Europium nitrate or europium acetate are capable of converting into Eu2O3 during a heat treatment process or converting into europium nitride (EuN) by reduction nitriding.

    摘要: An aluminum nitride-based ceramic sintered body is provided, which is manufactured by sintering an aluminum nitride powder comprising aluminum nitride as a main component, carbon in an amount of 0.1 wt % or more to 1.0 wt % or less, and containing oxygen in an amount that is not greater than 0.7 wt %, wherein carbon and oxygen are dissolved in grains of the aluminum nitride powder. The a-axis length of the lattice constant of the aluminum nitride is in a range of 3.1120 Å or more to 3.1200 Å or less, and the a c-axis length of the lattice constant is in a range of 4.9810 Å or more to 4.9900 Å or less. The volume resistivity of the aluminum nitride-based ceramic sintered body at 500° C. is 109 Ω·cm or more.
