High-Purity & Electronic Grade Fine Metal Powders

The trend toward miniaturization and high frequency in semiconductors and electronic components imposes unprecedented strict requirements on metal powder purity, particle size distribution, and oxygen content.

UrbanMines integrates three flagship highpurity monolithic products to precisely match core raw material demands:

· Highpurity spherical molybdenum powder

· Spherical nickel powder for MLCC internal electrodes (nano/submicron)

· Photovoltaic conductive silver powder

Spherical Molybdenum Powder

With a high melting point (2623℃) and excellent thermal conductivity, it is a foundational material for thermal spraying, semiconductor sputtering targets, and nearnet shaping of precision molybdenum components.

UrbanMines strictly selects products with particle size > 50 μm to avoid export control risks and ensure compliant overseas shipments. The powder offers stable apparent density, excellent Hall flow rate, and uniform normal particle size distribution.

Spherical Nickel Powder

A key material for MLCC internal electrodes. Driven by surging demand for miniaturized, highcapacitance MLCCs in AI servers, 5G/6G communications, and new energy vehicles, we produce nano and submicron spherical nickel powder via plasmaheated vapor condensation (PVD).

Our products feature high purity and narrow particle size distribution, satisfying the ultrafine powder requirements for 008004size MLCCs. We are among the few domestic suppliers of highend MLCC nickel powder.

Photovoltaic Conductive Silver Powder

The core component of photovoltaic cell conductive pastes, directly affecting cell photoelectric conversion efficiency and reliability.

UrbanMines provides customized photovoltaic silver powders compatible with PERC, TOPCon, BC, and HJT full technology routes. With tightly controlled particle size (D50: 0.5–1.5 μm) and excellent dispersibility, they effectively lower sintering temperature, improve printing activity, and meet overseas customer demand for Ntype celldedicated silver powder.
