After fired at 1600℃, with the increase of zircon addition the bulk density of the samples increases while apparent porosity decreases. When zircon addition is 4%, the strength is the best, and the photomicrograph of the sample exhibits a densely packed microstructure, with larger and better developed grains of periclase and spinel. Meanwhile, the direct bonding of solid phases is reinforced.

在1600℃热处理下，随着w(ZrSiO4)的增加，试样的体积密度增大，显气孔率变小，试样力学强度在w(ZrSiO4)为4%时达到最大值。w(ZrSiO4)为4%的试样整体显微结构致密，固相直接结合程度提高；并且方镁石和尖晶石晶粒的晶粒尺寸粗大，晶粒发育比较完整。

Metallic nickel powder is taken as a matrix; a chemical method is adopted to prepare a product required by cladding ferrites on the surface of the nickel powder; the mass ratio of the ferrites to the nickel compound powder is between 1 to 5 and 1 to 0.01; the grain diameter of the nickel powder is 0.5 to 5 microns; the ferrites are ferrites of spinel type or ferrites of magneto plumbite type.
