2. Introduction to main business or products during the reporting period
The company is a high-tech enterprise specializing in the R & D, production and sales of synthetic diamond products. Its main products include diamond single crystal, diamond micro powder and cultivated diamond.
Diamond single crystal and diamond micro powder products have excellent properties such as superhard, wear resistance and corrosion resistance. They are advanced inorganic non-metallic materials with high efficiency, high precision, semi permanent and environmental protection. They are core consumables for the production of sawing, cutting, grinding, drilling and other processing tools for high hard, brittle and difficult to process materials. The terminal application fields widely cover building materials and stones, exploration and mining, machining Clean energy, consumer electronics, semiconductor and other industries. At the same time, the company continues to increase R & D investment, continue to tap the advantages of thermal, optical, electrical, acoustic and chemical properties such as high sensitivity, high light transmittance, high power, high thermal conductivity and high electron migration of diamond single crystal and diamond micro powder products, and strive to explore the possibility of their industrial application in emerging fields as functional materials.
Cultivated diamond products are comparable to natural diamonds in crystal structure integrity, transparency, refractive index and dispersion. As an emerging choice in the field of diamond consumption, cultivated diamond products can be used to make diamond jewelry such as diamond rings, necklaces, earrings and other fashion consumer goods. During the reporting period, the company seized the opportunity of the transformation of the global diamond consumer market, continued to invest in R & D resources, improved the synthetic technology level of cultivated diamonds, and made continuous breakthroughs in the R & D of cultivated diamonds in the direction of large particles, high-grade and multi colors. The cultivated diamond business will develop into an important profit growth point of the company in the future.
The company always adheres to technology research and development as the center, has independent intellectual property rights in the key technologies and process control of artificial diamond production, and has mastered a full set of core technologies for artificial diamond production, including raw material formula, manufacturing of new sealed pressure transmission medium, large cavity Synthesis Series technology, high-grade cultivated diamond synthesis technology, diamond powder preparation technology, etc. Since its establishment, the company has always focused on the R & D and production of synthetic diamond products. At present, the company has formed three core product systems: diamond single crystal, diamond micro powder and diamond cultivation. The product structure is rich and the synergy effect is obvious, which can quickly respond to the market demand. The company’s products have strong competitive advantages in terms of grade, stability and process applicability. The company has leading advantages in the market segments of special diamond products such as micro powder for on-line sawing and special shaped octahedral diamond spinel, ultra-fine diamond single crystal and high-grade large particle cultivated diamond for IC chip superfinishing.
Since its establishment, the company has focused on the R & D, production and sales of synthetic diamond products closely around the national strategic development plan of new materials and the development trend of diamond consumption market, combined with its own technical advantages and the cluster advantages of artificial diamond industrial base, and the main business has not changed significantly.
The company’s products mainly include three categories: diamond single crystal, diamond micro powder and cultivated diamond. Diamond single crystal products can be further subdivided into grinding grade single crystal, sawing grade single crystal and large single crystal according to different particle morphology and application fields. Diamond micro powder products can be further subdivided into grinding micro powder Fine powder for wire saw and fine powder for other tools. Various types of synthetic diamond products of the company have certain differences in particle morphology, product performance and application fields. The specific conditions are as follows:
