Abstract:
The present invention discloses CrN thermoelectric material and its preparation method, which belongs to the field of thermoelectric materials. Here, we provide a study for thermoelectric properties, hardness, wear-resisting performance and thermal stability of CrN. These results show that CrN possesses excellent mechanical properties and thermal stability. The hardness of the bulk CrN sample is as high as 735.76 HV, which is far superior to most of thermoelectric materials. The thermogravimetric analysis test indicates that CrN remain stable at 873 K. Friction and wear test results demonstrate that the low friction coefficient (˜0.42) and good wear resistance of CrN. The maximum ZT value of 0.104 is observed at 848 K. In this way, CrN may be a promising thermoelectric material in extreme environment application which requires both mechanical and thermoelectric properties. Such as collision avoidance systems and outerspace.

Claim (Index 3):
The method for preparing the CrN thermoelectric material, as described in  claim 2 , wherein in the step 1, a proportion of Cr (NO 3 )  3 \u00b79 H 2 O, PEG10000, and the deionized water is: 16.00 g: 8.00g: 400 ml, a hybrid ultrasonic time is 0.5-1 h, with let stand for 6 to 12 h, a drying temperature is 333 K, and a drying time is 12-24 h.
