On December 9, Gelonghui reported that shenzhen sunxing light alloys materials (603978.SH) announced that after in-depth research and technical exchanges between the two parties, it was jointly believed that ceramic semiconductors components materials will be the development trend in the future. Based on the company's accumulated production technology experience and foundation in ceramic materials (alpha spherical aluminum oxide), and the rich experience of Hongxin semiconductors in the application of ceramic materials, both parties intend to cooperate to replace imported high stock price ceramic materials (alpha spherical aluminum oxide), achieving large-scale production and application of ceramic materials.

Recently, the company signed an "Investment Agreement" with Hongxin semiconductors. The two parties agreed to invest in the establishment of a joint venture company, Ganzhou Purui Ceramic Semiconductor Materials Co., Ltd. (tentative name, subject to the final business registration information), with a registered capital of 10 million yuan, where the company will contribute 7 million yuan in mmf and physical assets, holding 70%; Hongxin semiconductors will contribute 3 million yuan in mmf, holding 30%.
