Embodiment 1
[0021] 1. Preliminary preparation:
[0022] The preparation of the assembly of rare earth compound and calcium silicate: After mixing 100g of lanthanide rare earth metal compound and 150g of absolute ethanol, put it in the reactor, adjust the pH value of the reaction solution to 7.8 with a mass fraction of 10% ammonia solution At the same time, under the conditions of temperature at 35°C, far-infrared radiation power of 300w and ultrasonic power of 1500w, 50 parts of calcium silicate powder were added three times, stirred for 2 hours, and finally centrifuged at a speed of 1000r / min. After washing and drying the white product, an assembly of rare earth compounds and calcium silicate is obtained.
[0023] After calculation, the yield of rare earth compound and calcium silicate assembly is 45.8%.
[0024] The substances prepared above are used in the preparation of the following high-strength magnesium-aluminum alloys.
