Yunnan Chihong Zinc & Germanium has reported that its current annual production capacity for indium phosphide wafers stands at 150,000 units (ranging from 2 to 4 inches in diameter). Driven by the burgeoning demand within the optical communication sector and escalating raw material costs, prices for these products have witnessed a recent uptick. The company has commenced large-scale deliveries to downstream epitaxial manufacturers or device producers equipped with epitaxial capabilities.
In addition, the company's optical fiber-grade germanium offering is germanium tetrachloride tailored for optical fibers, boasting an annual production capacity of 60 metric tons. This product has been consistently manufactured for several years, with a clientele that encompasses renowned domestic optical fiber producers.
Furthermore, the company's "Germanium Wafer Construction Project for Space Solar Cells" was initiated in March 2025, with a planned construction duration of 18 months. By the close of 2025, it is projected to attain an annual production capacity of 1.25 million units (based on a 4-inch equivalent), with the capacity expected to double to 2.5 million units upon the project's full fruition.
