Description
先ず、無添加の場合には、1700℃まで昇温して、相対密度が約95%の焼結体が得られた。この焼成温度及び相対密度は一般的に知られている値と一致している。
Y2O3粉末とB2O3粉末を量論比でY3BO6を得られる比率(9.3wt%)より過剰のB2O3量を加え、混合した後圧粉し坩堝にいれ1400℃10時間の大気雰囲気焼成を行った。これを粉砕し、再度B2O3を加え圧粉し坩堝にいれ1400℃10時間の大気雰囲気焼成を行った後粉砕した。このようにして得られた粉末は、XRDによりY2O3やB2O3が存在しないY3BO6の単一相であることを確認した。なお、Y3BO6であることは、JCPDSカード34―0291と一致していることから判断した。
このようにして得たY3BO6粉末を用いて、Y3BO6粉末(比重4.638g/cm3)とY2O3粉末(比重5.031g/cm3)を体積割合で、1、5、10、20、50、75vol%となるように秤量し、均一に混合した粉末を標準試料とした。これら混合粉末をXRDにて測定を行った。得られた各XRDプロファイルにおいて、Y2O3の(khl)=(211)、(400)および(440)の回折ピーク強度の合算値IY2O3とY3BO6の(khl)=(003)、(−601)および(−205)の回折ピーク強度の合算値IY3BO6の比率を算出した。得られた値から、IY3BO6/(IY2O3+IY3BO6)を縦軸に、Y3BO6存在量を横軸にとると良い直線関係が得られ、これを検量線とした。
