We demonstrate the relevance of the Volume Specific Surface Area (VSSA) parameter to identify the nanoparticulate character of powder mixes based on either spherical constituent particles with bimodal size distributions (TiO₂), or fiber-like constituent particles with unimodal size distributions (sepiolite and sepiolite-based pigments). These new results indicate that VSSA could reasonably be proposed as an optional criterion in the future for the definition of nanomaterials based on the European Commission recommendation, provided certain requirements are fulfilled.

通过体积比表面积 (VSSA) 标准识别纳米材料：应用于粉末混合物

我们证明了体积比表面积 (VSSA) 参数与基于具有双峰尺寸分布 (TiO ₂ ) 的球形成分颗粒或具有单峰尺寸分布的纤维状成分颗粒 (海泡石和基于海泡石的颜料）。这些新结果表明，如果满足某些要求，则可以根据欧盟委员会的建议，合理地将 VSSA 作为未来定义纳米材料的可选标准。
