Therefore, the current application of tantalum-niobium new materials related high-tech industries include electronics, precision ceramics and precision glass industry; Keywords Electroacoustic and optical devices; hard alloy, aerospace and electronic energy industry; Keywords Biomedical engineering; Superconducting industry; Special steel and other industries. Tantalum and niobium play an important role in electronic industry, chemical industry, special alloy, vacuum technology and cutting-edge technology.
Electrolytic capacitors made of base-metal in electronic industry are featured with large capacitance, small leakage current, good stability, high reliability, good voltage resistance, long life and small volume. A large number of national defense, aviation, aerospace, electronic computers, high - grade civil electrical appliances and all kinds of electronic instruments in the electronic circuit.Pulp extraction; Fire decomposition and low acid extraction; off-line analysis, online analysis and microcomputer monitoring; cold crystallization of potassium fluorokerate; technology of continuous injection precipitation to produce low fluoride Ta2O5 and Nb2O5. High-purity Ta2O5, Nb2O5, high-flux mix-clarification extraction tank and combined extraction equipment are produced by peroxidation precipitation; international advanced vacuum rotary drying equipment for potassium fluodiate and far-infrared continuous drying equipment are adopted.
Tantalum wire: using a new type isostatic pressing molding, sintered sintering, rolling breakdown, multi-mode continuous drawing, special surface treatment, such as continuous annealing and continuous cleaning process, developed a series of 0.25-0.20-0.17 mm major silk export fine diameter, research level of 0.065 mm, tantalum wire tensile strength can control according to the customers' requirement in 32-168 KGF/was wide range, and can be used according to the customer request can improve the product's resistance to brittle, high temperature and bending resistance, resistance to guide performance. Ingots, rods, plates, tubes, sheets: Refined technical capability enhanced, there are 100, 200, 600KW electron beam furnace and 1 ton arc furnace, can produce a variety of specifications but saw metal and its alloy ingot, using it as raw materials, can produce various specifications of tubes, rods, plates, sheets, foil.
