Zusammenfassung:	The present invention provides a preparation method of processable ZTA/BN ceramics used for dentistry and relates to a preparation method of the processable ZTA/BN ceramics, solving the problem that the existing ZrO2 ceramics only can be processed by using a diamond cutter. The method comprises the following steps that: the mixture of AlN, H3BO3, Al2O3 and ZrO2 is cleaned by ultrasonic and stirred for 30 to 60 minutes, then ball milling is carried out for 5 hours, drying and sieved filtration are carried out, the mixed material after the sieved filtration is put into a graphite die, then the graphite die is put into a hot pressing furnace, and the graphite die is cooled to room temperature along with the furnace after temperature rise of three times to 800 DEG C, 1400 DEG C and 1600-1800 DEG C so as to obtain the processable ZTA/BN ceramics used for the dentistry. The processable ZTA/BN ceramics used for the dentistry, which is obtained by the method, has the strength of 600-730MPa and the toughness of 6.0-7.
