The invention relates to the field of ceramics, in particular to a honeycomb ceramic carrier as well as a preparation method and application thereof. The honeycomb ceramic carrier is prepared from thefollowing components in parts by weight: 20-30 parts of talcum, 10-30 parts of silicon dioxide, 5-10 parts of aluminum oxide, 10-30 parts of kaolin, 1-4 parts of boron oxide, 2-8 parts of strontium chromate, 1-4 parts of sodium molybdate, 15-30 parts of a pore forming agent, 0.2-2 parts of a dispersing agent, 0.2-1 part of an extrusion aid and 20-30 parts of water. Through the cooperation among the raw materials such as boron oxide, strontium chromate, sodium molybdate and the like; the mechanical property of the honeycomb ceramic is improved, the maximal axial compressive strength can reach28 MPa, the maximal transverse compressive strength can reach 5.6, the softening temperature is 1440 DEG C, the minimal thermal expansion coefficient can reach 0.37*10<-6>/DEG C, and the preparation process is easy to operate and environmentally friendly.
