Guangzhi Technology announced the Investor Relations Activity Record Form. The company has taken over all of the indium phosphide substrate assets of Pioneer Technology Group through a capital increase to hold Pioneer Technology Group, and has completed 3 generation 2 to 6 inch crystal iterations, and is one of the first manufacturers to launch a 6-inch indium phosphide substrate in China. At present, the products have been delivered in batches to domestic and foreign optical communication chip and device manufacturers, and the 6-inch indium phosphide substrate has received an order from a leading global customer. Currently, domestic customer demand is in the transition stage from 2 to 3 inches to 4 inches, and overseas customers are in the transition stage from 4 inches to 6 inches. Relying on the Group's mass production capacity of 8N grade high purity indium and preparation capacity of high purity electronic grade red phosphorus above 6.5N, the core equipment was self-developed and self-produced, and production expansion was not limited by material bottlenecks. In terms of the germanium industry chain, Inner Mongolia Guangzhi Mining Technology Co., Ltd., a wholly-owned subsidiary, was established in August to purchase lignite powder from the group to carry out germanium purification business. Purified metal germanium is mainly used in electronic material grade germanium dioxide, optical fiber-grade germanium tetrachloride, space photovoltaic grade molten germanium ingots, etc. The Xilin Gol League has proven reserves of 113 million tons of germanium-containing lignite and 3,458 tons of germanium metal reserves. The Group invested in the construction of an optical materials industrialization project locally, with a total investment of 5.3 billion yuan. After completion, the pretreatment capacity of lignite was 900,000 tons, and the annual production capacity of germanium crystal bars was 80 tons. The business has yet to contribute to the company's revenue and profits.
