这是首次由滑石、氧化铝和碳酸镁粉末成功合成纯尖晶石-镁橄榄石纳米复合材料的报道。在行星球磨机中混合适当比例的初始原料，并进行机械活化。得到的粉末在高温下进行了热处理。经过40h的机械活化和1200℃1h的热处理，得到了晶粒度为30-87 nm的纯尖晶石-镁橄榄石纳米复合材料。冷压强度测试结果表明，当尖晶石含量为10wt%时，烧成的尖晶石-镁橄榄岩坯体的强度最高(∼为67 Mpa)。这些样品的体积密度(BD)和表观孔隙率(AP)分别为1.46%和17%。
This is the first report of successful synthesis of pure spinel–forsterite nanocomposites from talc, alumina, and magnesium carbonate powders. Appropriate ratios of initial materials were mixed and mechanically activated in a planetary ball mill. The obtained powders were annealed at high temperatures. Pure spinel–forsterite nanocomposites with crystallites size in the range of 30–87nm were obtained after 40h of mechanical activation and subsequent annealing at 1200°C for 1h. The results of cold crushing strength (CCS) showed that the maximum strength of the fired spinel–forsterite bodies (∼67MPa) can be obtained in those samples with 10wt.% spinel. The bulk density (BD) and apparent porosity (AP) of these samples were 1.46% and 17%, respectively.
