First weigh the aluminum powder, magnesite and dolomite in a weight ratio of 1~2:2~4:6~15, and then calcine the magnesite and dolomite in a rotary kiln. After grinding, mix it with aluminum powder with a particle size of 80 to 100 mesh, press it into a ball shape under a pressure of 15 to 35 MPa, put it into a metal trough, put it into a reduction tank, and heat it at 1100 to 1170°C. Under vacuum conditions, after 6 to 8 hours, a chemical reaction occurs using aluminum powder as the reducing agent to generate magnesium.
How many points can you give me for this? This is a technology patent! ~~Haha
Haha, I’m just kidding, that’s how it was refined~!
