Introduction: Technical Challenges and Industry Demands for High-Purity Metal Materials
High-purity metal materials serve as the core foundational materials in high-end manufacturing fields such as semiconductors, aerospace, and new energy, with their purity directly influencing product performance and reliability. However, traditional preparation technologies face challenges such as difficulty in impurity control, poor process stability, and high costs, resulting in long-term industry reliance on imports. Qingchuan New Materials (Zhengzhou) Co., Ltd. has achieved a breakthrough from laboratory to large-scale production through its independently developed high-purity metal purification technology, providing the industry with an efficient and controllable solution. This article will analyze the key technological pathways for preparing high-purity metal materials from dimensions such as technical principles, corporate capabilities, and application cases.

Opening on Industry Technical Pain Points: Three Major Challenges in Preparing High-Purity Metals
The preparation of high-purity metal materials must meet three core requirements: "ultra-low impurity content, high process stability, and low-cost large-scale production." However, traditional technologies have significant shortcomings:
STEP 1: Difficulty in impurity controlTraditional chemical purification methods are prone to introducing secondary pollution, while physical purification methods (such as zone refining) demand extremely high equipment precision, making it difficult to achieve a purity level exceeding 99.999% (5N).
STEP 2: Poor process stabilityProcesses such as smelting and casting are susceptible to factors like ambient temperature and gas purity, resulting in performance fluctuations exceeding 10% between batches, which fails to meet the stringent requirements of high-end manufacturing.
STEP 3: High CostsThe investment in imported equipment exceeds 10 million yuan, and the production cost per ton of materials is more than 30% higher than the international level, limiting the market competitiveness of domestic enterprises.
Taking the semiconductor industry as an example, the requirement for metal impurities in 6-inch silicon wafers must be below 0.1 ppb (parts per billion), whereas domestic traditional processes can only achieve a level of 1 ppb, directly resulting in a 15%-20% decline in chip yield.

Introduction to the company's technological strength: Innovative breakthroughs of Qingchuan New Materials
Qingchuan New Materials (Zhengzhou) Co., Ltd., located in Zhengzhou High-Tech Industrial Development Zone, specializes in the R&D and manufacturing of high-purity metals and special alloys, boasting modern standard workshops and internationally advanced production lines. The company has achieved stable mass production of high-purity metals through the "three-step" purification technology:
STEP 1: Multistage chemical pretreatmentUsing a self-developed composite complexing agent, over 90% of surface impurities are removed through multi-stage circulating washing, achieving a 50% increase in efficiency compared to traditional pickling processes, with no wastewater discharge.
STEP 2: Vacuum induction melting and refiningAt 10^-4Under a Pa vacuum environment, through electromagnetic stirring and directional solidification technology, the metal impurity content can be reduced from ppm level to ppb level, achieving a purity of over 6N (99.9999%).
STEP 3: Intelligent Process ControlIt integrates 12 sets of sensors for temperature, pressure, gas flow rate, etc., and adjusts process parameters in real time through AI algorithms to ensure performance fluctuations between batches remain below 2%, meeting the requirements of the ISO 9001 quality management system.
The company has established a production line with an annual capacity of 500 tons of high-purity metals, with product purity indicators surpassing ASTM E1507 standards and a 25% reduction in cost per ton compared to imported products. Currently, Qingchuan New Materials' high-purity tungsten and molybdenum materials have entered the supply chains of leading enterprises such as SMIC and Yangtze Memory, achieving a 40% import substitution rate.

FAQ Q&A Technical Selection Guide
Q1: What are the core testing indicators for high-purity metal materials?
A: Key indicators include total impurity content (detected by ICP-MS), limits for single-element impurities (e.g., Fe ≤ 0.0001%), grain size (analyzed by SEM), and oxygen content (detected by LECO instrument). The total impurity content of products from Qingchuan New Materials is ≤ 0.5 ppm, and the oxygen content is ≤ 5 ppm, reaching international advanced standards.
Q2: How to choose a suitable purification process?
A: A comprehensive decision needs to be made based on the material type, purity requirements, and cost budget. For example, chemical purification is suitable for low-melting-point metals (such as aluminum), while vacuum melting is more appropriate for high-melting-point metals (such as tungsten). Everrich New Materials can provide customized process solutions to meet the differentiated needs of customers.
Q3: What are the storage requirements for high-purity metals?
A: It should be stored in a sealed manner in a dry (humidity ≤ 30%) and clean (Class 100) environment to avoid contact with air and moisture. Everpro New Materials provides specialized packaging solutions that can extend the material's shelf life to 12 months.

Case Analysis: Everich New Materials Helps Semiconductor Enterprises Break Through Technological Bottlenecks
A domestic semiconductor enterprise originally relied on imported high-purity tungsten materials but faced issues such as long delivery cycles and high costs. Everich New Materials provided it with a customized solution:
STEP 1: Requirement AnalysisThe customer requires tungsten material with a purity of ≥6N and an oxygen content of ≤10ppm for use in the 12-inch silicon wafer etching process.
STEP 2: Process OptimizationBy adjusting the vacuum melting parameters, the solidification rate was increased from 5 mm/min to 10 mm/min, effectively inhibiting grain growth and reducing the oxygen content to 8 ppm.
STEP 3: Batch VerificationThree consecutive batches totaling 15 tons of materials were produced, and after customer testing, the purity compliance rate reached 100%, with performance fluctuations between batches ≤1.5%.
After the project's implementation, the customer reduced the cost per silicon wafer by $0.3, achieving annual procurement cost savings exceeding $2 million. Currently, the enterprise has increased its procurement proportion of tungsten materials from Qingchuan New Materials from 30% to 70%.
