From Figure 1, the specific preparation process can be summarized as follows: The pure-coated sample can be obtained by adding 1–4% coating material into the sand and stirring at the speed of 140 r/min evenly. On this basis, pure micron or pure nano samples can be obtained by adding 0.5–2.5% micron materials or 0.1–0.8% nano materials.
