Introduction: With the surge in demand for high-end manufacturing, semiconductors and new energy industries, artificial diamond rough materials, as core basic materials, are ushering in global strategic opportunities. According to the "Global Industrial Diamond Market Report", the annual compound growth rate of this field will exceed 12% from 2023 to 2030, among which the production and application of diamond rough materials will become a key link in the upgrading of the industrial chain.
1. Artificial diamond rough materials: the "industrial teeth" of cutting-edge industries
Made by high temperature and high pressure (HPHT) or chemical vapor deposition (CVD) technology, it is widely used in precision tools, photovoltaic wire saws, semiconductor wafer processing and other fields due to its superhardness, wear resistance and thermal conductivity. Compared with natural diamonds, its cost controllable and uniform specifications make it an irreplaceable "super material" for modern industry.
Industry data shows that the global diamond rough material market size will exceed US$4.5 billion in 2023, and China, as the largest producer, will contribute more than 60% of the production capacity. Industrial clusters represented by Henan, Jiangsu and Shandong have seen the emergence of a number of technologically advanced diamond rough material manufacturers, which have achieved micron-level particle size control and purity breakthroughs through independent research and development.
2. Expansion of application scenarios: New energy and semiconductors have become the core driving force
1. Photovoltaic industry: The penetration rate of diamond wire saws for cutting silicon wafers exceeds 98%, and about 300,000 kilometers of diamond wire are required for each GW of single-crystal silicon wafer production capacity, which directly drives the demand for rough materials
2. Third-generation semiconductors: Silicon carbide (SiC) and gallium nitride (GaN) substrate processing relies on precision grinding and polishing of diamond rough materials, which increases processing efficiency by 5-8 times
3. Ultra-precision processing: Turbine blade air film hole processing in the aerospace field requires rough material particle size error ≤ 0.1μm
According to estimates by the International Energy Agency (IEA), the photovoltaic industry alone will create an incremental market of more than US$1.5 billion in artificial diamond rough materials by 2030.
3. Green Manufacturing: Sustainable development becomes the new benchmark for the industry
Faced with the wave of ESG investment, leading diamond rough material manufacturers are accelerating the layout of green production:
· Using six-sided top presses to replace traditional processes, a single device saves 40% energy
· Developing diamond rough material recycling technology to achieve a secondary utilization rate of grinding waste exceeding 75%
· EU carbon tariffs force companies to build a full life cycle carbon footprint management system
"Our newly built zero-carbon factory has 52% lower carbon emissions per ton of rough material than the industry average." A listed company disclosed in its annual report that environmental protection technology has become a core purchasing indicator for international customers.
IV. Future Outlook: Intelligence and customization reshape the industrial landscape
Industry experts pointed out that the diamond rough material industry will present three major trends:
1. Customized particle size: extending from general 40-60 mesh to 10nm ultra-fine rough materials
2. Intelligent production: digital twin technology realizes real-time regulation of the growth process
3. Cross-border application: quantum computing, biomedicine and other emerging fields open up incremental space
Conclusion: As the global industrial chain accelerates the high-end process, the strategic value of artificial diamond rough materials continues to highlight. Diamond rough material manufacturers with technical reserves and scale advantages are expected to occupy a dominant position in the 100 billion market.
