Abstract
【解決手段】 所定の主成分配合組成に対して、酸化ビスマスをBi2O3換算で0.05〜1.0重量%、酸化錫をSnO2換算で0.5〜3.0重量%、酸化クロムをCr2O3換算で30〜5000重量ppm添加するように構成する。

Description
このようにして得られた粉砕粉(フェライト粉)に、6%ポリビニルアルコール溶液を加えて混合した後、スプレードライヤを用いて造粒粉を得た。このようにして得られた顆粒を用いて、成形密度3.10Mg/m3となるように外径13mm、内径6mm、高さ3mmのトロイダル形状に成形した。このように成形した成形体を大気中で焼成温度900℃で2時間焼成して、トロイダルコアサンプルを得た。
焼結体の密度(df:単位はMg/m3)を、アルキメデス法を利用して得られた数値に基いて算出した。
トロイダルコアサンプルにワイヤを20回巻回した後、LCRメータにてインダクタンス値等を測定し、100kHzで−50℃〜25℃および25℃〜85℃における初透磁率(μi)の変化率をそれぞれ求めた(室温25℃を基準としている)。
すなわち、
ΔL/L(-50℃〜25℃)={L(-50℃)−L(25℃)}/L(25℃)×100 (%)
ΔL/L(25℃〜85℃)={L(85℃)−L(25℃)}/L(25℃)×100 (%)
ワイヤを20回ほど巻回したトロイダルコアサンプルについて直流電流を流した時のμの変化を測定し、μと直流電流の関係をグラフにする。次いで、このグラフを用いて直流電流0mA時の初期の透磁率μiが10%低下するときの電流値を計算するという手法によって、初透磁率μiの10%低下の電流値Idc10%down(mA)を求めた。
ディスク状のサンプルに電極を塗布した後、IRメータによって抵抗を測定し、寸法から比抵抗ρを算出した。
ファインセラミックスの常温における3点曲げ試験であり、JIS R1601-1981に準じて求める。数値が大きいほど抗折強度が大きい。
