The invention discloses a method for preparing a high temperature NTC (Negative Temperature Coefficient) thermistor material, which comprises the following steps of: according to a formula of CaWO4-xCeTiyO2y+2, weighing and analyzing pure powdered CaCO3, CeO2, TiO2 and WO3, placing the powder into a ball milling tank, adding deionized water and zirconium ball grinding stone and carrying out ball milling for four hours; drying ball-milled slurry, grinding the dried powder and sieving the powder through a 80-mesh sieve; presintering the sieved powder, ball-grinding the presintered powder again, drying and grinding the powder and sieving the power through the 80-mesh sieve to obtain uniform and fine powder; and finally, placing a dry-pressed sample into a high temperature furnace to sinter so as to obtain the thermistor material. A main crystal phase of the thermistor material prepared by the method disclosed by the invention is a scheelite phase; the thermistor material has room temperature resistivity of 5.642*10<6> to 1.982*10<9> ohm.cm and has material constant of 5,077 to 7,275K; in the integral test temperature range, a resistor temperature relation curve LnRho-1000 / T has good linearity; and the method is suitable for temperature measurement in the wide temperature range of room temperature to 1,000 DEG C.
