The pricing of nano-products is primarily driven by purity levels (e.g., 99.9% vs. 99.999%), particle size distribution (uniformity), and the specific surface area (SSA). Smaller particle sizes often require more complex synthesis methods like Chemical Vapor Deposition (CVD) or Laser Ablation, which increase energy consumption and equipment costs. Additionally, the dispersion stability—whether the particles are supplied as a dry powder or a stabilized suspension—affects the final quote due to the cost of specialized surfactants and solvents.
