ALEM
SiO₂ · 99.97% ultra-pure
ALEM is ultra-pure mesoporous SiO₂ produced from metallurgical slags of non-ferrous metallurgy (Ust-Kamenogorsk complex) via controlled destructurization and recrystallization. The technology does not synthesize a new material — it removes external mineral layers to 'liberate' a primordial crystal lattice free of induced dislocations, with quantum and electronic stabilization, and controlled phonon transport. The result: a quantum-grade substrate with thermal stability exceeding 3500°C.

- Self-glazing effect — forms a protective vitreous layer at critical temperature
- Thermal stability >2× the melting point of standard quartz (1713°C)
- Preserves piezoelectric properties with reduced noise floor
- Phonon transport suppression — eliminates thermal noise for quantum applications
- Produced from industrial metallurgical waste — sustainable sourcing
ALEM's Self-glazing effect creates a protective vitreous layer under critical heating, enabling structural integrity beyond conditions where conventional quartz disintegrates. Thermal stability exceeds 2× the melting point of ordinary quartz. Phonon transport suppression reduces thermal noise — critical for quantum computing substrates.
