前記主成分に対して、副成分として、リンをＰ換算で２〜６３ｐｐｍ、酸化ジルコニウムをＺｒＯ２換算で４３〜５９８０ｐｐｍ、酸化コバルトをＣｏＯ換算で０．０５〜２重量％含有することを特徴とする。
In order to achieve the above object, the ferrite composition according to the present invention comprises:
As main components, iron oxide is 46.0 to 49.89 mol% in terms of Fe 2 O 3 , copper oxide is 2.3 to 19.0 mol% in terms of CuO, and zinc oxide is 18.0 to 23 in terms of ZnO. Containing 5 mol%, the balance being composed of nickel oxide,
It is characterized by containing 2 to 63 ppm of phosphorus in terms of P, zirconium oxide 43 to 5980 ppm in terms of ZrO 2 , and cobalt oxide 0.05 to 2 % by weight in terms of CoO with respect to the main component . To do.

前記主成分に対して、副成分として、リンをＰ換算で２〜６３ｐｐｍ、酸化ジルコニウムをＺｒＯ２換算で４３〜５９８０ｐｐｍ、酸化コバルトをＣｏＯ換算で０．０５〜２重量％含有することを特徴とする。
Alternatively, the ferrite composition according to the present invention is
As main components, iron oxide is 46.0 to 49.89 mol% in terms of Fe 2 O 3 , copper oxide is 2.3 to 19.0 mol% in terms of CuO, and zinc oxide is 18.0 to 23 in terms of ZnO. 0.5 mol%, manganese oxide containing 0.01 to 2.1 mol% in terms of Mn 2 O 3 , the balance being composed of nickel oxide,
It is characterized by containing 2 to 63 ppm of phosphorus in terms of P, zirconium oxide 43 to 5980 ppm in terms of ZrO 2 , and cobalt oxide 0.05 to 2 % by weight in terms of CoO with respect to the main component . To do.
リンの含有量は、主成分に対して、Ｐ換算で、２〜６３ｐｐｍ、好ましくは３〜３０ｐｐｍ、より好ましくは５〜１０ｐｐｍである。リンの含有量が少なすぎると、焼結性が低下し、その結果、電力損失が増加する傾向にある。多すぎると、電力損失が増加する傾向にある。
The phosphorus content is 2 to 63 ppm, preferably 3 to 30 ppm, more preferably 5 to 10 ppm in terms of P with respect to the main component . When there is too little content of phosphorus, sinterability will fall and as a result, it exists in the tendency for electric power loss to increase. When the amount is too large, power loss tends to increase.
酸化ジルコニウムの含有量は、主成分に対して、ＺｒＯ２換算で、４３〜５９８０ｐｐｍ、好ましくは１０８〜３２８０ｐｐｍ、より好ましくは２２０〜１５３０ｐｐｍである。酸化ジルコニウムの含有量が少なすぎると、電力損失が増加する傾向にある。多すぎると、電力損失が増加すると共に、飽和磁束密度が低下する傾向にある。
The content of zirconium oxide is 43 to 5980 ppm, preferably 108 to 3280 ppm, more preferably 220 to 1530 ppm in terms of ZrO 2 with respect to the main component . When the content of zirconium oxide is too small, power loss tends to increase. When the amount is too large, the power loss increases and the saturation magnetic flux density tends to decrease.
酸化コバルトの含有量は、主成分に対して、ＣｏＯ換算で、０．０５〜２重量％、好ましくは０．１〜１．５重量％、より好ましくは０．２〜１．０重量％である。酸化コバルトの含有量が少なすぎると、電力損失が増加する傾向にある。多すぎると、電力損失が増加すると共に、飽和磁束密度が低下する傾向にある。 The content of cobalt oxide is 0.05 to 2% by weight, preferably 0.1 to 1.5% by weight, more preferably 0.2 to 1.0% by weight in terms of CoO with respect to the main component . is there. When the content of cobalt oxide is too small, power loss tends to increase. When the amount is too large, the power loss increases and the saturation magnetic flux density tends to decrease.
