SiC semiconductor material for plasma ignition, preparation method and sparking plug
The invention relates to the field of conductor material preparation, and relates to a SiC semiconductor material for plasma ignition, a preparation method and an ignition plug, the material comprises the following components by mass: 30-70% of SiC powder, 10-20% of ZrO2 powder, 10-30% of mullite powder and 10-30% of composite sintering aid powder; lu2O3, Yb2O3, Y2O3 and La2O3 are added into the composite sintering aid powder, so that the material can resist the high temperature of 1500-1600 DEG C and has good ion erosion resistance; zrO2 is added, so that the mechanical property and the reliability of the material are improved; by adding Lu2O3, the electrical property of the material can be improved; due to the high-volume-fraction SiC, the semiconductor ignition plug prepared from the material has low ignition voltage and high spark energy; the open porosity of the material is extremely low, and the spark corrosion resistance is improved; certain closed pores are formed in the material, so that the thermal shock resistance can be improved. The sparking plug solves the problems of poor high temperature resistance, insufficient electric spark corrosion resistance and insufficient thermal shock resistance of the sparking plug prepared from a SiC semiconductor material.
