In March 2026, the National High-Purity Graphite Industry Development Conference was held in Zhengzhou, China. The new horizontal continuous graphite high-temperature purification technology developed by the professional R&D team successfully passed the industrialization appraisal, officially breaking the technical bottleneck of high energy consumption and low efficiency of traditional graphite purification. This technological breakthrough has completely changed the backward situation of intermittent high-temperature purification in the global high-end graphite industry, greatly reduced the production energy consumption and carbon emissions of ultra-high-purity graphite, and promoted the global graphite industry to move towards green and low-carbon high-end development.
For a long time, the high-purity purification link has been the core link with the highest energy consumption and the largest carbon emission in the graphite deep-processing industry. The traditional vertical intermittent purification process needs repeated high-temperature heating and cooling cycles, with large heat loss, high unit energy consumption and low production efficiency. The production of one ton of 5ppm ultra-high-purity graphite consumes a huge amount of electric energy, resulting in high production costs and restricting the large-scale popularization of high-end ultra-purity graphite products. At the same time, traditional purification technology is prone to unstable impurity removal effect, resulting in inconsistent batch performance of high-purity graphite products.
The newly industrialized horizontal continuous purification technology realizes continuous feeding, continuous high-temperature purification and continuous discharging through structural innovation of purification equipment and optimization of temperature control system. Compared with the traditional process, the new technology saves two-thirds of production energy consumption, the purification efficiency is increased by more than 50%, and the impurity removal precision is further improved. It can stably produce ultra-high-purity graphite products with total impurity content below 3ppm, and the batch stability of products is greatly improved, fully meeting the ultra-high standard requirements of aerospace and semiconductor fields.
The popularization of the new purification technology has a revolutionary impact on the global high-end graphite industry. First, it greatly reduces the production cost of ultra-high-purity graphite components, improves the market competitiveness of high-end products, and helps accelerate the popularization of high-purity graphite in high-end manufacturing fields. Second, it effectively reduces the carbon emission of graphite deep processing, helping global graphite enterprises meet green supply chain certification and carbon tariff policy requirements. Third, the continuous production mode improves production efficiency, solves the problem of insufficient global high-end graphite production capacity, and relieves the tight supply of ultra-high-purity graphite products.
At present, this new domestic purification technology has reached the international leading level, and no similar mature industrialized technology has appeared in Europe, America and Japan. Chinese high-end graphite deep-processing enterprises have taken the lead in mastering this core green low-carbon technology, further consolidating China's leading position in the global high-end graphite industry chain.
Huixian Jincheng Abrasive & Graphite Mold Factory took the lead in introducing and upgrading the new horizontal continuous purification technology in the industry, completing the full-process technical upgrading of high-purity graphite production in 2026. On the basis of the original multi-stage purification process, the company optimizes and matches the new continuous purification equipment and process parameters, further improving the purity stability and production efficiency of high-end graphite products, and reducing the unit production energy consumption by 68%.
After the technical upgrading, Jincheng Graphite's ultra-high-purity graphite products have more stable performance, the batch impurity content error is controlled within ±0.5ppm, and the product qualification rate is increased from 99.2% to 99.9%. The new technology completely solves the batch performance inconsistency problem of traditional intermittent purification products, making the company's semiconductor and aerospace-grade graphite components more in line with the ultra-stable production requirements of global high-end precision manufacturing enterprises.
In terms of green production, the popularization of the new technology further reduces the carbon footprint of Jincheng Graphite's products, making the company's green manufacturing level reach the international advanced level. The product carbon emission index is far lower than the EU and international industry standards, which helps the company better adapt to the global green supply chain access rules and expand the high-end overseas market share.
At present, Jincheng Graphite is continuing to optimize the new continuous purification process, combining vacuum impregnation technology and surface treatment technology to build a full-process green and high-efficiency high-purity graphite production system. With the continuous iteration of purification technology, the company will further reduce production costs, improve product performance, and lead the global high-end graphite industry to achieve green, low-carbon and high-quality development.
