Premium products are in high demand and supply is tight, driving up the value of high-purity quartz sand.

Industry data shows that the mainstream price of high-purity quartz sand for optical fibers has now risen to 48,000 to 55,000 yuan per ton. Among these, high-end products with a purity above the 6N level are “extremely hard to obtain.” Due to the need to improve the self-sufficiency rate of domestic production, the tight supply and demand in the industry continues to intensify. The recent surge in high-purity quartz sand prices is driven by explosive demand from the downstream optical fiber industry. “High-purity quartz sand is used in multiple stages of optical preform production, and quartz-based products are also required in fiber production,” said the head of a company engaged in quartz product processing. As orders increase at preform factories, the demand for “peripheral products” including high-purity quartz sand naturally grows.
