Step 2, SiO 2 powder, magnesium oxide powder, lime powder and bentonite are put in ball mill, and ball mill exists 35-50 degree Celsius of lower ball milling 2-5 hour, to powder mix homogeneously by the sieve of 80-120 mesh, obtains the second mixture；
Step 3, vegetable oil is added in the second mixture and 10-20 minutes is processed at 120-155 degree Celsius, then is cooled to 65-90 degree Celsius and 1500-1800rpm rotating speed process 30-60 minutes, obtain the 3rd mixture；
Step 4, by the first mixture, the 3rd mixture and plant ash mix homogeneously, then with static pressure machine 800-1200MPa's Kept for 1-3 minutes under pressure, make idiosome；
Step 5,1.5-4 hours are sintered by idiosome under nitrogen or argon atmosphere under 650-820 degree Celsius, are cooled down Finished product is obtained to room temperature.
