Natural Flake Graphite · Madagascar
Product Catalogue
Etablissements Gallois S.A. supplies natural flake graphite with fixed carbon ranging from 80% to 99%, flake sizes +32 to −100 mesh. Custom specifications available on request.
MADA1
Premium grade — No.1 mine (Antsirakambo)
MADA1 graphite has a perfect crystalline structure, high density, and in ash a very low content of substances unfavourable for purification. It is the first choice for high-technology applications.
Key Applications
- Feedstock for downstream spheroidization and Li-ion anode qualification
- Expandable graphite (fire-proofing / intumescent)
- High-purity graphite
- Military & aerospace graphite
- Man-made diamond feedstock
- Advanced refractories
MADA2
Industrial grade — No.2 mine (Marovintsy)
MADA2 is a robust industrial-grade flake graphite well-suited for high-volume commodity applications with broad and proven track record across metallurgy and refractory sectors.
Key Applications
- Metallurgy
- Refractories
- Crucibles
- High-purity graphite feedstock
- Sealing materials
- Brake pads & pencils
