Ceramic tool with integrated temperature sensing and cutting functions, preparation method and application thereof

A ceramic tool with integrated temperature sensing and cutting functions, comprising a ceramic matrix, wherein

• at least one thermoelectric layer is provided on first and second surfaces of the ceramic matrix, wherein
• the at least one thermoelectric layer provided on the first surface is a positive thermoelectric layer;
• and the at least one thermoelectric layer provided on the second surface is a negative thermoelectric layer;
• the ceramic matrix is formed by sintering a first matrix material, a first binding agent and a first reinforcing phase, and
• the thermoelectric layers on the first and second surface are formed by sintering of a thermoelectric material;
• wherein
• the first matrix material comprises one or more of Al2O3, Si3N4 and CBN;
• the first binding agent comprises one or more of Mo, Ni, Co, W and Cr;
• the first reinforcing phase comprises one or more of TiC, WC, SiC, MgO, Cr2O3, TiO2 and ZrO2;
• the thermoelectric material for the positive thermoelectric layer comprises ZrB2 and SiC;
• and
• the thermoelectric material for the negative thermoelectric layer comprises ZrB2, SiC, and graphite.
