Introduction

Titanium dioxide powder is one of the most important inorganic functional materials in modern manufacturing. With global consumption exceeding 6.5 million tons annually (industry estimate range 2024–2025), it plays a critical role in coatings, plastics, paper, ink, cosmetics, and advanced functional materials.

The performance of titanium dioxide is not uniform. Instead, it is determined by crystal structure, particle engineering, surface coating, and manufacturing purity. These differences lead to multiple titanium dioxide powder types, each designed for specific industrial applications.

Modern industries demand higher opacity, UV resistance, dispersion stability, and environmental compliance. As a result, titanium dioxide production has evolved into a highly engineered, standards-driven chemical industry.
