| titleOfInvention | Method for producing porous ferrite and radio wave absorber using the same |
| abstract | [PROBLEMS] A method for producing a porous ferrite capable of performing sintering in which cracks and cracks are prevented and capable of appropriately forming pores in a sintered body, and increasing the radio wave absorption characteristics to a higher frequency and a wider area by making the porous ferrite. To provide a radio wave absorber excellent in mechanical strength and weather resistance. [Solution] In manufacturing, a ferrite powder as a base material is weighed and calcined at a predetermined temperature, and then the calcined body is pulverized. Granulate. The granulated ferrite powder is mixed with fine organic particles together with a thermoplastic powder having a low melting point and a binder function. The additive is burned off to obtain a porous sintered body. Organic particles (starch) and thermoplastic powder (paraffin fine particles) are added in a total amount of 0 to 30 wt%, and the mixing ratio of the organic particles is increased in a range of 0 to 5 wt% in accordance with the amount of the thermoplastic powder. . When the thickness of the sample d is 0.8 cm, the return loss is about 20 dB or more at about 100 to 750 MHz, which corresponds to almost the entire VHF to UHF band. [Selection diagram] FIG. |
