Zadient produces ultra‑high‑purity (8N) granular silicon carbide source material for physical vapor transport crystal growth. Its controlled particle size and high bulk density enable manufacturers of SiC wafers to achieve higher yields, longer boules, and lower defect densities for power and RF devices. The company offers three certified grades and supplies up to 7,000 t/yr to global wafer producers.

Problem
The silicon carbide (SiC) semiconductor supply chain is constrained by limited availability of ultra‑high‑purity source material, which hampers the growth of large‑diameter, low‑defect SiC crystals needed for power and RF devices in electric vehicles and renewable‑energy systems.
Solution
Zadient supplies granular SiC source material with purity levels up to 99.999999 % (8N) using an industrial‑scale chemical vapor deposition (CVD) process. The material is offered in a controlled particle‑size range (1–12.5 mm) with high bulk density (≈1.92 g/cm³) and a cubic morphology that promotes stable sublimation during physical vapor transport (PVT) crystal growth. By delivering consistent, low‑impurity feedstock, Zadient enables higher crystal yields, longer boules, and reduced defect densities for large‑diameter wafers. The product line includes three grades (SP, HP, UP) tailored to standard N‑type, ultra‑low‑defect N‑type, and semi‑insulating crystals. Production capacity of 7,000 t/yr ensures short lead times and reliable supply for high‑volume manufacturers.
Features
- 8N (99.999999 %) purity achieved through Siemens‑type CVD followed by precise comminution and surface treatment.
- Customizable particle‑size distribution (1–12.5 mm) and cubic particle shape for optimal flowability and uniform sublimation rates in PVT reactors.
- High bulk density (1.92 g/cm³) allowing greater crucible loading and more uniform thermal fields during crystal growth.
- Three certified grades (SP, HP, UP) addressing standard, ultra‑low‑defect, and semi‑insulating crystal growth requirements.
- Production capability of 7,000 tons per year with flexible packaging options (5 kg bags to 100 kg fiber drums) for global logistics.
- Rigorous quality assurance using GDMS, SIMS, and ISO‑certified testing to verify bulk and surface purity and particle‑size conformity.
- Over 100 patents protecting the source‑material process and related crystal‑growth technologies.
