Corundum Block TY-G93
The Corundum Block TY-G93 is a synthetic aluminum oxide refractory product designed for continuous operation above 1800°C, with a base composition of greater than 90% Al2O3. It is engineered for high abrasion resistance and low thermal expansion, making it suitable for furnace linings, kiln furniture, and petrochemical reactor components. The block is manufactured using high-purity calcined alumina, pressed under high pressure, and sintered to achieve dense microstructure.
Typical industry properties include a bulk density of 3.45 g/cm³, a thermal expansion coefficient of 0.55% at 1000°C, and a maximum service temperature of 1850°C. Unlike lower-grade fireclay, this block resists chemical attack from alkali vapors and molten slag. The material has no defined grain structure, resulting in uniform thermal performance. Standard shapes include rectangular blocks and custom profiles, but exact dimensions are not listed in the source.
This product is primarily sourced by steel foundries, cement plants, and glass manufacturers needing refractory linings for high-temperature zones. Buyers typically order in metric tons, with packaging in reinforced wooden crates. Trade terms are commonly FOB or CIF, though the listing does not specify MOQ or lead time. Buyers must confirm packaging details, handling requirements, and export documentation directly with the supplier before shipment.

| Maximum Service Temperature | Exceeds 1800°C (typical for high-grade synthetic corundum) |
| Bulk Density | 3.40 to 3.50 g/cm³ (standard for dense synthetic alumina blocks) |
| Thermal Expansion (at 1000°C) | Approximately 0.55% (typical for low-expansion corundum) |
| Cold Crushing Strength | Minimum 100 MPa (typical for high-alumina refractories) |
| Porosity | Less than 16% (standard for sintered synthetic corundum) |
| Abrasion Resistance | High, suitable for erosion-prone zones (standard for TY-G93 grade) |
| Chemical Resistance | Resistant to alkali vapors, molten glass, and metal oxides (typical for >90% Al2O3) |
| HS Code | 6903.20 (for refractory alumina blocks) |
| Packaging | Wooden crates with internal padding (typical for refractory shipments) |

Sourcing Corundum Block TY-G93 from Zhengzhou Sunrise Refractory Co., Ltd. - China Import Guide
Before ordering, confirm the exact Al2O3 content, bulk density, and thermal expansion coefficient for the specific batch. Request test reports referencing ASTM or ISO standards. Verify that the block’s composition is free of iron and alkali contaminants if used in glass or cement applications. Do not assume that 'TY-G93' implies compliance with any international standard unless documented by the supplier.
Lead time and incoterms are not disclosed. Buyers must confirm whether FOB Zhengzhou, CIF port, or DDP terms apply, and whether the supplier provides export documentation. Packaging must include anti-vibration padding and moisture barriers. Confirm if palletization is used and whether the supplier provides loading supervision. Payment terms like T/T or L/C should be negotiated directly.
Upon delivery, inspect blocks for surface cracks, chipping, or discoloration. Retain samples for third-party lab testing if performance is critical. Ensure the packing list matches the HS code 6903.20 and includes batch numbers for traceability. For furnace lining applications, conduct a thermal cycle test on a sample before full installation. Document all inspection results to support warranty claims if needed.
