超细金属微粒材料的剩磁通密度和矫顽磁力均优于氧化铁和二氧化铬,可用来制造磁记录带,尤其是制造金属磁带,在最近广泛引人注目.制造这种材料的日本某公司已收到大量来自国内和国外制造磁带的厂家要求提供样品的申请.
The remanent flux density and the coercive force of the ultrafine metal particulate material are superior to iron oxide and chromium dioxide and can be used to make magnetic recording tapes, especially metal tapes, which have attracted wide attention recently. A company has received a large number of domestic and foreign manufacturers of magnetic tapes to request samples.
