The invention relates to a foamed ceramic wave-absorbing material and belongs to the field of composite wave-absorbing materials. The ceramic wave-absorbing material comprises, in percentage by mass, 40%-60% of silicon carbide micro-powder, 10%-30% of ferrite magnetic nanofibers, 5%-15% of calcium carbonate micro-powder, 5%-10% of silica powder, 3%-6% of carboxy methyl cellulose and 5%-15% of silica sol. Compared with the prior art, the foamed ceramic wave-absorbing material has the advantages as follows: the material is good in wave absorbing property, mechanical property and heat resistance, a nano ferritefiber material is composited in particular and has the higher length-diameter ratio and magnetic permeability than nano ferrite powder.
