The core technology of tantalum powder material is the improvement of specific capacitance.
In the 1980s, Japan could reach 2000 mfv/g, and the United States reached 12,000 mfv/g.
The R&D team of NXDF Tantalum Technology Corporation reformed the potassium sodium fluorotantalate reduction process and created China's first set of stirred sodium reduction process technology equipment, which made a breakthrough in the specific volume of capacitor-grade tantalum powder in China.
In 1991, the specific capacitance value of tantalum powder developed by NXDF finally reached 10,000 mfv/g. Say.
In 1992, NXDF's capacitor grade tantalum powder began to enter the international market, successively exported to the United States, Britain, Germany, Japan and other countries.
The specific capacitance value of tantalum powder has risen from 30,000, 50,000 to 70,000 mfv/g, and the annual export volume has also increased from 5,000 tons, 20,000 tons to 100,000 tons, which has been increasing at a rate of 45% for 8 consecutive years.
In the 21st century, NXDF has successively established 11 new production lines for tantalum, niobium and beryllium, and 11 scientific research achievements applied to industrial development have won national and provincial science and technology progress awards; successfully organized and built Asia`s largest and highest level of equipment Tantalum-niobium wet process production line; the level of tantalum-niobium refining and alloy preparation has reached the international leading level; the introduction of advanced thermite reduction method has shortened the gap between the technical level of tantalum-niobium products and the international advanced level by 20 years.
The scientific research strength of NXDF has driven the development of China's tantalum and niobium industry and the electronics industry, and the technological level of China's tantalum and niobium industry has achieved a transformation from a follow-up to a parallel and even a partial lead. The research on beryllium has reached the international advanced level, and has successfully completed many major national aerospace and aviation projects.
