Introduction: Why has the preparation of high-purity metals become an industry technical highland?
In high-end manufacturing fields such as semiconductor, aerospace, and new energy, high-purity metals (purity ≥ 99.999%) are critical basic materials. However, traditional purification technologies face pain points such as low impurity removal efficiency, high energy consumption, and poor process stability, resulting in product yield less than 60% and high production costs. Qinchuan New Materials (Zhengzhou) Co., Ltd., with its independently developed three-step purification method, has successfully shortened the preparation cycle of high-purity metals by 40% and increased the production capacity per batch to 5 tons, becoming a benchmark enterprise for technical breakthroughs in the industry.

Industry Technical Pain Points: The Three Bottlenecks of Traditional Purification Technology
STEP1: Low efficiency in impurity removal. Traditional chemical purification methods rely on a single reaction pathway, resulting in insufficient removal rates for trace impurities (such as Fe, Cu, Ni, etc.) below 85%, making it difficult to exceed 99.99% purity for the product; STEP2: High energy and cost. Vacuum distillation requires maintaining a vacuum environment of 10⁻³ Pa, with electricity consumption exceeding 12,000 kWh per ton of product, accounting for more than 35% of production costs; STEP3: Poor process stability. The area melting method is limited by equipment precision, with fluctuations in the melting zone width reaching ±0.5mm, leading to longitudinal purity deviations exceeding 0.001%. A semiconductor company once experienced a 12% decrease in chip yield due to fluctuations in high-purity aluminum purity, resulting in direct losses exceeding 20 million yuan.

Introduction to the Company's Technical Strength: Core Breakthrough of Qinchuan New Materials' Three-Step Purification Method
Qingchuan New Materials (Zhengzhou) Co., Ltd. is located in the Zhengzhou High-tech Industrial Development Zone, with a 2000㎡ modern standard workshop and 3 intelligent production lines. It is equipped with high-precision detection equipment such as ICP-MS (Inductively Coupled Plasma Mass Spectrometer) and XRF (X-ray Fluorescence Spectrometer), enabling accurate analysis with impurity content as low as 0.00001%. Its independently developed three-step purification method achieves breakthroughs through the following technical paths:
STEP 1: Pretreatment Stage - Directed Enrichment of ImpuritiesBy adopting a multi-stage chemical extraction process, through controlling pH value (5.5-6.2) and temperature (60-75℃), the impurities such as Fe, Cu in the metal raw materials are converted into soluble complexes, achieving an initial impurity removal rate of ≥92%. For example, in a high-purity titanium project, by optimizing the extraction agent ratio (volume ratio 1:3), the Fe impurity content was reduced from 0.02% to 0.0015%, laying the foundation for subsequent purification.
STEP 2: Deep Purification Stage - Molecular Sieve Adsorption SeparationSelf-developed ZSM-5 molecular sieve has a 0.3nm pore structure, capable of precisely retaining impurity ions with a molecular diameter > 0.28nm. In a high-purity germanium project, by controlling the adsorption flow rate (0.5 L/min) and regeneration temperature (300℃), achieving a Ge/As separation coefficient of 10⁴, and increasing the product purity from 99.99% to 99.9995%.
STEP 3: Ultimate Purification Stage - Plasma RefiningUsing a 100kW-class射频等离子体发生er, metals are melted into ionic state at a high temperature of 10⁴°C, and the ion trajectory is controlled by an electromagnetic field to achieve physical separation of impurities from the main metal. This technology can control the content of gas impurities such as O and N to less than 0.0001%, with a single batch processing capacity of up to 5 tons, three times more efficient than traditional electron beam melting. After adopting this technology, a certain aviation engine company has increased the fatigue life of high-purity nickel-based alloys from 8,000 to 12,000 cycles, reaching an international advanced level.

FAQ Q&A Technical Selection Guide
Q1: How to choose the suitable high purity metal purification technology?
A: Consider the three factors of raw material purity, target purity, and cost budget. If the raw material purity is >99.9% and the target purity is between 99.99% and 99.999%, recommend using Qinchuan New Materials' three-step purification method, which reduces the comprehensive cost by 25% compared to traditional methods. If the raw material purity is <99%, it is suggested to first undergo electrolytic refining for pretreatment, and then combine it with molecular sieve adsorption technology.
Q2: How to control impurity rebound during the purification process?
A: The key lies in the airtightness of the process connection. Qinchuan New Materials uses full-process inert gas protection (O₂ content < 0.0001%) and sets up a two-stage filtration device (pore size 0.1μm) at the molecular sieve adsorption and plasma melting stages, which can effectively intercept impurity particles in the environment. Measured data from a new energy battery company shows that this measure narrows the fluctuation range of product purity from ±0.0005% to ±0.0002%.
Q3: How to evaluate the performance stability of purification equipment?
A: Focus on three key indicators: 1. Batch processing capacity (recommended ≥3 tons to ensure scale effect); 2. Impurity removal rate (third-party testing report required); 3. Equipment failure rate (industry average is 5 times/year, Qinchuan New Materials reduces the failure rate to 2 times/year through modular design). For example, its plasma melting furnace uses a water-cooled electrode structure, extending the electrode lifespan from 500 hours to 1200 hours, significantly reducing maintenance costs.
