MAGNESIUM, COPPER AND ZINC BASED FERRITE POWDER FOR MICROWAVE-ABSORPTION HEATING BODIES, AND MICROWAVE-ABSORPTION HEATING BODY ARRANGED BY USE THEREOF
PROBLEM TO BE SOLVED: To provide MgCuZn based ferrite powder for microwave-absorption heating bodies, which makes possible only to appropriately select a heat-up stop temperature in a wide temperature region of 30-250°C, but also to reach the heat-up stop temperature in a short time.SOLUTION: MgCuZn based ferrite powder for microwave-absorption heating bodies comprises: as principal components, an iron oxide accounting for 46-51 mol% in terms of FeO, a copper oxide accounting for 2-15 mol% in terms of CuO, a zinc oxide accounting for 3-33 mol% in terms of ZnO and the balance consisting of a magnesium oxide and inevitable impurities; and as a subcomponent, a bismuth oxide accounting for 1-8 pts.mass to 100 pts.mass of the principal components in terms of BiO. The MgCuZn based ferrite powder has a volume density of 1 g/cmor more.
【課題】３０〜２５０℃という広い温度域で昇温停止温度を任意に選択できるだけでなく、昇温停止温度まで短時間で到達可能なマイクロ波吸収発熱体用ＭｇＣｕＺｎ系フェライト粉を提案する。【解決手段】鉄酸化物をＦｅ2Ｏ3換算で４６〜５１ｍｏｌ％、銅酸化物をＣｕＯ換算で２〜１５ｍｏｌ％および亜鉛酸化物をＺｎＯ換算で３〜３３ｍｏｌ％含み、残部は酸化マグネシウムおよび不可避的不純物からなる基本成分と、この基本成分１００質量部に対して、副成分として、ビスマス酸化物をＢｉ2Ｏ3換算で１〜８質量部含有するＭｇＣｕＺｎ系フェライト粉とし、さらに、このＭｇＣｕＺｎ系フェライト粉の嵩密度を１ｇ／ｃｍ3以上とする。【選択図】なし
