The Types segmentation distinguishes particle specifications that influence pricing tiers and adoption rates. Standard‑grade spherical BN particles, produced via conventional gas‑phase synthesis, dominate the market due to cost‑effectiveness and sufficient performance for general polishing and lubrication, representing the bulk of sales. High‑purity grades, with impurity levels below 10 ppm, are essential for semiconductor and aerospace applications where contaminant control is critical; they command a premium and occupy a smaller, high‑value niche. Nanometer‑scale particles (≤100 nm) are emerging for advanced thermal‑interface materials, offering enhanced surface area and heat‑transfer efficiency, though current volumes remain limited by production complexity. Functionalized particles, surface‑treated to improve dispersibility in polymers or fluids, address specific composite and lubricant formulations, adding value through tailored chemistry. Each type contributes uniquely to the market’s revenue composition, with standard‑grade driving volume, while high‑purity, nanometer‑scale, and functionalized variants expand the market’s technological breadth.
