Introduction: Technical Challenges and Industry Demands for High-Purity Metal Materials
High-purity metals and special alloys are key foundational materials in high-end manufacturing fields such as semiconductors, aerospace, and new energy, with their purity, uniformity, and stability directly influencing the performance of end products. However, traditional preparation processes face challenges such as difficulty in impurity control, high energy consumption, and poor batch stability, posing technological bottlenecks that constrain industry development. Qingchuan New Materials (Zhengzhou) Co., Ltd. has achieved breakthroughs in high-purity material preparation through its independently developed special alloy production line and precision processing technology, providing efficient and reliable solutions for the industry.

Opening on Industry Technical Pain Points: Three Core Challenges in Preparing High-Purity Metals
STEP 1: High difficulty in impurity control. High-purity metals (e.g., above 6N) impose extremely stringent requirements on the content of light elements such as oxygen, carbon, nitrogen, and metallic impurities. Traditional smelting processes are prone to introducing furnace charge contamination, leading to fluctuations in purity. For instance, semiconductor-grade monocrystalline silicon requires an oxygen content below 10 ppma, a standard that is difficult to achieve consistently with conventional processes.
STEP 2: Energy consumption and cost pressures. The preparation of high-purity materials requires a vacuum or inert gas environment, with equipment energy consumption accounting for as high as 40%-60% of production costs, and equipment depreciation costs increasing significantly during large-scale production.
STEP 3: Poor batch stability. Factors such as fluctuations in raw material composition and deviations in process parameter control can easily lead to performance variations in products across different batches, affecting the usage efficiency of downstream customers. A photovoltaic enterprise once experienced a 0.5% fluctuation in the conversion efficiency of solar cells due to differences in silicon material batch purity, resulting in significant economic losses.

Introduction to the company's technological strength: Innovative Solutions from Everpro New Materials
Qingchuan New Materials (Zhengzhou) Co., Ltd., located in Zhengzhou High-Tech Industrial Development Zone, specializes in the research, development, and manufacturing of high-purity metals, special alloys, and their products. The company is equipped with internationally advanced production lines for special alloys and precision processing equipment, with its core advantages reflected in the following three aspects:
STEP 1: Impurity control technology. By employing a combined process of multi-stage vacuum induction melting (VIM) and electron beam melting (EB), along with inert gas protection and directional solidification techniques, the oxygen content can be stably controlled below 5 ppma, and the carbon content below 0.5 ppma. For instance, the 6N-grade tantalum sputtering target customized by the company for a semiconductor enterprise achieved a purity of 99.9999%, with a total impurity content below 0.0001%.
STEP 2: Energy-saving and consumption-reduction design. The independently developed intelligent temperature control system can monitor the smelting temperature in real time and dynamically adjust power output, achieving 20%-30% energy savings compared to traditional processes. Meanwhile, the equipment adopts a modular design, increasing the single-unit production capacity to 5 tons per batch and reducing unit energy consumption costs by 15%.
STEP 3: Full-process quality control. From raw material inspection to finished product delivery, 12 quality inspection procedures are implemented, including ICP-MS (Inductively Coupled Plasma Mass Spectrometry) testing, metallographic analysis, hardness testing, etc., to ensure that products comply with international standards such as ASTM E1019 and GB/T 20975. The company's laboratory is equipped with high-end analytical equipment such as Scanning Electron Microscope (SEM) and X-Ray Diffraction (XRD) instruments, achieving a detection precision at the ppb level.

FAQ: A Q&A Guide to Technology Selection
Q1: How to select the preparation process for high-purity metals?
A: It is necessary to comprehensively consider target purity, material properties, and cost. For instance, metals below 6N can be processed using Vacuum Induction Melting (VIM), which is cost-effective; whereas metals above 6N require a combination of Electron Beam Melting (EB) or Chemical Vapor Deposition (CVD). Qingchuan New Materials can provide customized process solutions based on customer needs. For example, when a customer required 7N-grade tungsten rods, we employed a combined VIM+EB process, achieving a purity of 99.99997% that met the requirements for semiconductor sputtering targets.
Q2: What are the testing indicators for high-purity metals?
A: Key indicators include the content of principal components, total impurities, gas content (such as oxygen, nitrogen, and hydrogen), and physical properties (such as density and hardness). The Qingchuan New Materials Laboratory employs ICP-MS to detect metallic impurities with a sensitivity of 0.001 ppm and uses a LECO oxygen-nitrogen-hydrogen analyzer to measure gas content with an accuracy of ±0.1 ppm. For instance, the oxygen content detected in the titanium alloy rods we supplied to an aviation enterprise was merely 0.008%, significantly lower than the standard requirement of 0.015%.
Q3: How can the production costs of high-purity metals be reduced?
A: We can start from three aspects: process optimization, equipment upgrading, and scale effects. Qinchuan New Materials has reduced energy consumption by 25% and increased the production capacity of a single piece of equipment by 40% through an intelligent temperature control system. Meanwhile, it has adopted recycling technology to recover metals from waste materials, raising the raw material utilization rate to 98%. Taking a customer with an annual demand for 100 tons of high-purity aluminum as an example, after adopting our solution, the unit cost has decreased by 18%, and the delivery cycle has been shortened by 30%.
