High-Purity Germanium Production For Ultimate Precision Gamma-Spectroscopy
High-Purity Germanium (HPGe): Unique Semiconducting Material for Gamma and X-ray Detection
• Lowest band gap = best energy resolution
• No competitors in complex radionuclide identification (mixtures, low activity)
• Application domains: – Radioecology– Atomic energy– Nuclear security– Cargo scanning– Science

I. Ultra-deep purification & single crystal growth
II. Detector block manufacturing (+n/p layers, contacts, cryostat)
III. End-user device assembling(+electronics, high-voltage supply, etc.)

•Extreme purity required: |nD – nA| < 1010 cm-3
•Global market: $170–280 million/year•Crystal production segment: $60–120 million/year•Raw material ~1 500 $/kg, HPGe ~15 000 $/kg
Our niche
Present-day Limitations
Technology• Multiple Zone-Refining:
– Time/resource consuming– Safety issues
• Czochralski pulling:– Risk of cracking– Bigger size is hardly
achievable
Market• Umicore EOM – the only
crystal supplier• ORTEC + Canberra = oligopoly
Consequences• Overpricing • 100% import share • Long delivery & repair• Possible ban due to sanctions• New application development
is hindered

Our Tech Innovations
Key Ingredients• Rotating Container method:
Czochralski + Bridgman• Low temperature gradients:
precise thermal control
Advantages• Minimized contact with walls• Enhanced purification efficiency• Low H2 consumption
• Thermal stress decrease
Potentialities• Superior crystal size• Single setup
Current status• Prototype implementation &
small-scale production start• Investments required: 300 k$• Period: 3 years
