Honeycomb ceramic block is a very important industrial products. It is mainly used in flue gas purification. It is usually used in the RTO flue gas treatment equipment.
The main material of the honeycomb ceramic block as below
- 1.Cordierite
- 2.Mullite
- 3.Cordierite and Mullite
- 4.Alumina
- 5.Dense Alumina
- 6.Stoneware
Different material has different content of Alumina. The ability of temperature resistance is also different.
Physical property of different material
| Performance | Alumina | Dense alumina | Cordierite | Mullite-Cordierite | Mullite | Stoneware |
| Density (g/cm’) | 2.0-2.3 | 2.4-26 | 1.6-1.9 | 1.7-2.0 | 2.0-2.4 | 1.7-2.0 |
| Bulk density (g/cm5) | 0.65-0.8 | 0.65-0.8 | 0.6-0.7 | 0.65-0.75 | 0.65-0.8 | 0.65-0.75 |
| Coefficient of thermal expansion (xio */r *) (RT-800X：) | ≤6 | ≤6 | ≤3 | ≤3.5 | ≤5.5 | ≤6.5 |
| Specific heat Capacity (J/kg • k) | 950-1150 | 1000-1200 | 900-1100 | 900-1100 | 1000-1150 | 900-1100 |
| Thermal- conductivity (w/mkX20H000r) | 1.5-2.0 | 1.5-2.0 | 1.2-1.8 | 1.4-1.9 | 1.5-2.0 | 1.4-1.9 |
| Thermal-shock | ≥300 | ≥300 | ≥350 | ≥350 | ≥350 | ≥300 |
| Max. working temperature | 1350 | 1350 | 1150 | 1250 | 1450 | 1200 |
| Water absorption | ≤20 | ≤5 | ≤22 | ≤20 | ≤20 | ≤10 |
The water absorption is also a very important data for the honeycomb ceramic block. The common water absorption is between 10%-20%. But we also produce customized products with nominated water absorption even 0% water absorption rate
The honeycomb ceramic block has many standard sizes with different hole numbers.
The 150mm*150mm*150mm and 150mm*150mm*300mm are the most popular sizes.
The specification with different holes as below,
| L*W*H (mm) | 150×150 x 300(150) | ||||
| Number of cell | 25×25=625 | 40 * 40=1600 | 43 * 43=1849 | 50 x 50=2500 | 60×60=3600 |
| Cell width (mm) | 4.95 | 3.02 | 2.81 | 2.38 | 1.98 |
| Thickness of Inner-wall (men) | 1.0 | 0.7 | 0.65 | 0.6 | 0.5 |
| Surface area (m’/m’) | 577 | 886 | 950 | 1084 | 1294 |
| Opening rate (%) | 68 | 65 | 65 | 63 | 63 |
We also design some grooves for the ceramic honeycomb block. It is a special requirement of the customers. The grooves type and size could be produced according to customers nominated requirement.
