The recycling prices for sputtering targets in the international market are eye-catching. Taking ruthenium targets as an example, according to London Metal Exchange (LME) data, the ruthenium price is expected to stabilize between $1,000 and $1,200 per ounce by 2025. High-purity ruthenium scrap (ruthenium content ≥10%) commands recycling prices of $150–180 per ounce, significantly higher than many traditional metals.
Significant variations exist in the recycling value of different precious metal targets. Semiconductor-grade ruthenium powder commands recycling prices of $218–268 per ounce, while industrial-grade ruthenium scrap fetches approximately $80–120 per ounce.
Prices fluctuate due to geopolitical and supply chain factors, with daily swings reaching ±15%. Professional sputtering target recycling services utilize advanced detection technologies to accurately assess scrap value, ensuring fair returns for clients.
In semiconductor manufacturing, sputtering targets are critical materials for chip production. Alumina targets are used in the deposition of insulating and dielectric layers during integrated circuit manufacturing. They effectively isolate circuits to prevent interference, reduce current leakage, and enhance product reliability and durability.
Ruthenium targets hold particular value in the semiconductor industry, especially in the interconnect layer manufacturing of chips below 7nm. Ruthenium films ensure stable current transmission, improving chip performance and reliability.
As process nodes advance below 5nm, the sputtering rate requirements for target materials in 3D device structures have increased to over 10nm/min. Ruthenium targets demonstrate outstanding performance in this domain, becoming indispensable materials for high-end chip manufacturing.
The semiconductor industry demands extremely high purity for target materials, typically requiring a minimum standard of 99.99% (4N grade). This makes the recycling value of semiconductor scrap targets significantly higher than that of scrap from other sources.
Sputtering target recycling prices are not arbitrarily quoted but calculated using precise precious metal recycling formulas: Actual Recycling Price = (Actual Waste Purity ÷ Standard Purity) × (Actual Recovery Rate ÷ Benchmark Recovery Rate) × Daily Metal Benchmark Price - Processing Costs.
The first variable is purity comparison. Industrial-grade iridium oxide typically has a standard purity of 99.99%. If the actual purity of the scrap falls below this standard, the price is discounted accordingly.
The second variable is recovery rate comparison. The industry benchmark recovery rate is generally set at 95%. If the scrap has complex forms or contains difficult-to-separate impurities, the actual recovery rate may decrease, affecting the final quote.
The third variable is the daily metal benchmark price. The authoritative reference is the London Metal Exchange (LME) spot quote, which updates globally in real-time to ensure pricing transparency.
Finally, processing costs are deducted, which depend on the scrap form and processing difficulty. Bulk target material incurs lower processing costs, while thin-film scrap requires complex separation processes, significantly increasing costs.
Ruthenium target recycling prices depend on multiple factors. High-purity ruthenium targets (ruthenium content ≥10%), such as semiconductor target scrap and spent ruthenium catalysts, command recycling prices of approximately $150–180 per ounce.
Medium-purity ruthenium scrap (1%-10% ruthenium content), such as electroplating waste solutions and photovoltaic electrode waste, commands a recovery price of approximately $80-120 per ounce. Low-purity scrap (ruthenium content <1%), including electronic component coatings and laboratory waste solutions, fetches around $30-60 per ounce.
Significant regional variations exist in ruthenium target recycling. Areas with advanced technical capabilities typically offer recycling quotes 15%-20% higher than less developed regions, directly linked to detection precision and recovery processes.
Technological advancements have enhanced ruthenium target recycling efficiency. Microwave pyrolysis technology can strip ruthenium from ceramic carriers at 2000°C, boosting recovery rates from 75% to 99.2% and substantially increasing recycling value.
Semiconductor manufacturing plants are the primary source of high-quality sputtering target waste. Discarded targets, sputtering chamber cleaning residues, and substandard thin-film substrates generated during chip production all contain recoverable precious metals.
Display device manufacturers also generate substantial quantities of sputtering target waste. Ruthenium and iridium oxide targets used in OLED screen production, despite being only tens of nanometers thick, retain considerable recycling value.
The photovoltaic industry represents another significant source. Various precious metal targets are employed in solar cell manufacturing, with recoverable precious metals present in both production waste and end-of-life photovoltaic panels.
Research institutions and university laboratories also generate small quantities of high-purity sputtering target waste. These residues typically exhibit high purity, minimal processing complexity, and relatively high recycling value.
Ruthenium-iridium alloy coatings used in aerospace and defense applications withstand temperatures up to 4000°C. The unit price for recycling these specialty alloy wastes often far exceeds that of ordinary scrap.
