Silicon Dioxide Market Outlook:
Silicon Dioxide Market size was valued at USD 10.89 billion in 2025 and is likely to cross USD 19.69 billion by 2035, registering more than 6.1% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of silicon dioxide is assessed at USD 11.49 billion.
The silicon dioxide market’s growth is due to the expansion of end use industries and rising demand for high-performance electronic devices. Silicon dioxide is a critical material in the manufacturing of semiconductors and the growth of the semiconductor industry is poised to drive demand for the material. For instance, in June 2024, Evonik, one of the global leaders in specialty chemicals, announced investments in the North America semiconductor industry and began production of ultra-high purity colloidal silica in the U.S. Evonik’s ultra-high purity colloidal silica production plant will be the first of its kind in North America. It augurs well for the future of the silicon dioxide market as it paves the way for more industry stakeholders to expand silica production.
Another major growth driver of the silicon dioxide market is its growing adoption in the food & beverage industry as a stabilizer anti-caking agent. The market benefits from favorable regulatory clearance for the use of silica as a food additive, fostering consumer trust and allowing manufacturers to invest in supplying food-grade silica. For instance, in October 2024, the European Food Safety Authority (EFSA) concluded that silicon dioxide as a food additive does not cause safety concerns and it applies to all age demographics. Furthermore, busy consumer lifestyles have led to rising demand for ready-to-eat food, which requires silicon dioxide as an additive to maintain product quality and extend shelf life. The favorable trends within the food & beverage sector are projected to assist a sustained demand for food-grade silica that key industry players can leverage.
Additionally, the financial performance of major players in the silicon dioxide market highlights the potential of profit within the sector. For instance, in February 2024, U.S. Silica Holdings, Inc., announced their annual report for the financial year 2023, highlighting that the full year net income of USD 146.9 million increased 88% year-over-year, while full year company contribution margin of USD 549.7 million increased 16% year-over-year. The improved product mix in the industrial and specialty products segment of the company played a major role in the growth indicating favorable opportunities in the silicon dioxide market. Profitable performance by key players is reinforcing investor confidence and indicates the growing demand for silicon dioxide. The global silicon dioxide market is poised to leverage the favorable trends and maintain its robust growth curve by the end of the forecast period.
