With the continuous expansion of the application scale of high-end graphite materials in new energy, semiconductor, aerospace and other fields, the global market demand for ultra-high-purity graphite materials has increased explosively in 2026. For a long time, high-end ultra-high-purity graphite products in the global market mainly rely on high-energy-consumption synthetic graphite production process. The synthetic graphite production needs ultra-high-temperature graphitization treatment above 2800℃, with huge energy consumption, long production cycle and high comprehensive production cost, resulting in the high price of global high-end graphite materials, which restricts the large-scale popularization and application of high-performance carbon materials in various industries.
Natural graphite ore has the advantages of abundant global reserves and low raw material cost, which is an ideal raw material for low-cost preparation of ultra-high-purity graphite materials. However, traditional natural graphite purification technology has obvious technical defects. The traditional physical flotation process can only remove large particle impurities, and it is difficult to eliminate trace inorganic impurities and metal ions, with the highest purification purity only reaching 95%-98%, which cannot meet the purity requirements of high-end industrial scenarios such as semiconductors and nuclear energy. The traditional chemical purification process has problems such as large reagent consumption, serious environmental pollution and long process flow, with high comprehensive cost and low production efficiency, and cannot realize large-scale industrial production.
In 2026, the innovative composite deep purification technology of natural graphite has completely broken the industrial cost bottleneck of high-end carbon materials. The new generation of "physical fine sorting + low-temperature composite chemical purification + high-temperature deep impurity removal" integrated process can efficiently remove trace impurities in natural graphite ores, and stably prepare ultra-high-purity graphite products with purity above 99.99%. This technology abandons the high-energy-consumption and high-pollution links of the traditional process, greatly reduces production energy consumption and comprehensive cost, and realizes the green and low-cost large-scale production of ultra-high-purity graphite from natural graphite.
The popularization of new natural graphite purification technology has profoundly changed the global high-end graphite supply pattern. It breaks the long-term dependence of high-end ultra-high-purity graphite on high-cost synthetic process, makes full use of low-cost natural graphite ore resources, and reduces the production cost of global high-end graphite materials by more than 25%. At the same time, the green and low-carbon purification process effectively reduces carbon emissions and environmental pollution in the graphite production process, which is in line with the global dual-carbon development strategy and green industrial upgrading trend.
As a pioneer in the innovation of global natural graphite deep purification technology, Jincheng Graphite has independently developed a new generation of low-cost and green composite purification process after years of technical research and process optimization. The enterprise optimizes the proportion of chemical reagents and low-temperature reaction parameters, realizes efficient and thorough removal of trace impurities in natural graphite, and the purification purity stably reaches 99.995%, meeting the ultra-high-purity standards of semiconductor, nuclear energy and high-end electronic materials.
Compared with the traditional purification process, Jincheng Graphite's innovative purification technology reduces the production energy consumption of ultra-high-purity graphite by 30%, reduces the use of chemical reagents by 45%, and reduces the comprehensive production cost by 28%. The whole production process has low carbon emission, no waste liquid pollution and high resource utilization rate, realizing the perfect integration of high purification efficiency, low cost and green environmental protection. At the same time, the enterprise optimizes the process flow, shortens the production cycle by 40%, and greatly improves the mass production capacity of ultra-high-purity graphite.
At present, Jincheng Graphite has applied the self-developed green purification technology to large-scale industrial production, realizing the mass supply of low-cost and high-quality ultra-high-purity natural graphite products. The enterprise's products have replaced part of high-cost synthetic graphite products in the global high-end market, effectively reducing the material procurement cost of global downstream high-end manufacturing enterprises. Relying on technological advantages, Jincheng Graphite has become an important low-cost high-end graphite material supplier in the global market.
Industry experts said that the breakthrough and popularization of natural graphite deep purification technology will completely reverse the cost dilemma of the global high-end carbon material industry, accelerate the popularization of high-performance graphite materials in various high-end industrial fields, and drive the overall upgrading of the global carbon material industry chain. As a core technology innovator in the industry, Jincheng Graphite will continue to optimize purification process parameters, further reduce production costs and improve product purity, and continuously empower the low-cost and green high-quality development of the global graphite industry.
