Segmentation by Types categorizes anhydrite flour into three principal families: Natural anhydrite, Synthetic anhydrite, and Calcined anhydrite, each further divided into fine‑grade, coarse‑grade, and specialty‑grade subtypes. Natural anhydrite, mined directly from evaporite deposits, typically supplies coarse‑grade material suited for bulk cement blending, contributing modestly to market volume due to limited purity control. Synthetic anhydrite, produced via controlled dehydration of gypsum, offers fine‑grade particles that enhance powder flow and reactivity, capturing a larger share of high‑performance construction and cement markets. Calcined anhydrite, generated by high‑temperature treatment of natural gypsum, yields specialty‑grade flour with engineered crystal morphology, supporting advanced applications such as high‑strength concrete additives and precision agricultural formulations. The differentiation among these types influences pricing, supply chain logistics, and end‑use suitability, collectively shaping the market’s structural composition and growth trajectory.
