Product details
Shijiazhuang, Hebei Province — May 31, 2026 — Shijiazhuang Hongtao Technology Co., Ltd. has expanded its industrial microwave sintering portfolio with a dedicated microwave vertical tower kiln targeting magnesium oxide (MgO), zirconium dioxide (ZrO₂), and aluminum oxide (Al₂O₃) processing — three materials critical to refractories, advanced ceramics, and electronic substrates.
Traditional shaft and push-plate kilns struggle with temperature gradients, slow heating rates, and excessive energy consumption. Hongtao's vertical tower design integrates microwave volumetric penetration heating with a gravity-fed vertical chamber, ensuring every particle receives simultaneous internal heating. This eliminates cold spots, guarantees uniform crystal-phase conversion, and reduces sintering cycle times by up to 40%.
| Parameter | Conventional Shaft Kiln | Hongtao Microwave Tower Kiln |
|---|---|---|
| Temperature Uniformity | ±15–20°C | ±5°C |
| Energy Efficiency | Baseline | ↓ Over 50% |
| Sintering Speed | 6–10 hours | ↓ 40% faster |
| Product Consistency | Variable | Highly uniform |
The kiln operates on scalable microwave power modules (10kW–200kW), accommodating pilot batches to full industrial throughput. Custom heating curves ensure precise control over MgO periclase formation, ZrO₂ tetragonal-phase stabilization, and Al₂O₃ densification — all at temperatures exceeding 1,600°C.
Founded in 2010 and recognized as a provincial-level tech-based SME, Hongtao Technology employs a R&D team where 30% hold master's degrees or above. The company exports to South Korea, Japan, Singapore, and Kazakhstan, and guarantees 24-hour after-sales response with 48-hour on-site arrival.
