Kaiyada has always focused on the research, development, production, and sales of new semiconductor materials such as high-purity elements and high-purity compounds. Based on solidifying the industrial chain of "high-purity tellurium—tellurium-based compounds," Kaiyada continuously develops and introduces cutting-edge materials demanded by the market. Advantages in professional talent and technology have laid a solid foundation for the company's technological innovation, product development, and industrial growth. To date, Kaiyada has developed over 200 types of high-purity materials, leading the domestic high-purity field. On average, the company independently develops 10-15 new high-purity materials annually and has applied for more than 30 patents cumulatively.
