一方、酸化物焼結体の焼結密度B(g/cm3)は、JIS−R1634−1998に準拠してアルキメデス法で測定する。
相対密度(%)=(B/A)×100。
[実施例1〜11、比較例1〜10、参考例1〜3]
<酸化物焼結体の作製>
原料粉末として、純度99.99重量%、平均粒径0.5μmの酸化インジウム粉末、純度99.9重量%、平均粒径0.2μmの酸化ジルコニウム粉末、純度99.9重量%、平均粒径0.2μmの酸化イットリウム粉末、及び純度99.99%、平均粒径0.2μmの酸化ハフニウム粉末を準備した。表1に記載された原子比となるように、これらの原料粉末を秤量して乾式ボールミルで混合し、成形用の混合粉末を得た。混合粉末の平均粒径は0.2μmであった。
(焼成条件)
・昇温速度 :50℃/時間
・焼結保持温度 :1600℃
・保持時間 :5時間
・焼結雰囲気 :昇温開始前(室温)から降温時の100℃に到達するまで
純酸素ガスを炉内に導入
・降温速度 :100℃/時間
・成形体の重量/酸素流量:0.9[kg/(L/min)]。
(組成)
各実施例、各比較例及び各参考例の酸化物焼結体の組成を、市販のICP発光分析装置を用いて、ICP発光分析法により定量した。そして、原子比を求めた。その結果を表1に示す。なお、酸化物焼結体の組成は、成形用の混合粉末の組成とほぼ同一であった。
(相対密度)
各実施例、各比較例及び各参考例の酸化物焼結体の相対密度を求めた。相対密度は、酸化物焼結体の理論密度をA、焼結密度をBとしたとき、下記式によって求められる値である。理論密度A及び焼結密度Bの測定方法は上述のとおりである。測定結果を表1に示す。

各実施例及び各比較例で作製した酸化物焼結体を、円板形状(直径:4インチ=101.6mm)に加工した。スパッタリングターゲットとして用いる際にスパッタリング面となる面は、平面研削盤とダイヤモンド砥石を用いて研磨した。研磨の際に砥石の番手を変えることにより、中心線平均粗さ(Ra)を調整した。このようにしてスパッタリングターゲットを作製した。作製したスパッタリングターゲットのスパッタリング面のRaを、市販の表面性状測定装置(装置名 サーフテストSV−3100 ミツトヨ製)を用いて測定した。その結果は表1に示す通りであった。
