Summary:The invention discloses a method for preparing natural hydroxyapatite biological ceramic by using a microwave method. The method comprises the following steps: adding poval in natural hydroxyapatite, carrying out ball milling with a wet method, mixing and drying; insulating for 1-4 hours at the temperature of 450 DEG C in a high temperature furnace after molding in a mould, and then sintering with a microwave sintering furnace, wherein the sintering temperature is 1150 DEG C-1300 DEG C, the insulation time is 5-30 minutes; and cooling along with the furnace so as to obtain the natural hydroxyapatite biological ceramic. By using the method in the invention, the sintering time is greatly shortened, and simultaneously the mechanical property of the natural hydroxyapatite biological ceramic is improved.
