Ceramic Lining Bricks (Tiles)
Main Chemical Compositions & Categories
| Category Focus | Typical Al2O3 Content | Primary Function |
| Wear-Resistant Tiles | 90% to 99% Al2O3 | Extreme Abrasion and Impact |
| Insulating Fire Bricks | 30% to 70% Al2O3 / SiO2 balance | Thermal Insulation & Energy Savings |
Key Properties and Performance
| Property | Wear-Resistant Tiles (High Density) | Insulating Fire Bricks (Low Density) | Variation with Al2O3 Content |
| Temperature Under Load (TUL) | Very High (1600°C+) | Moderate to High (1260°C to 1760°C) | Increases in both categories as Al2O3 content rises. |
| Thermal Shock | Good (due to high purity) | Excellent (due to high porosity) | Improves in IFBs with lower density/higher porosity. |
| Corrosion | Excellent resistance to acids, alkalis | Good resistance to alkali attack | Increases in both with higher Al2O3 and lower glass phase. |
| Wear Resistance | Exceptional (Mohs 9 Hardness) | Poor (easily damaged/eroded) | Increases drastically in dense tiles with higher Al2O3 and BD (Bulk Density). |
Advantages and Key Characteristics
Wear-Resistant Ceramic Tiles
- Primary Advantage: Extreme Hardness (second only to diamond), providing superior protection against sliding and impact abrasion in material handling.
- Structure: Sintered, ultra-high density, non-refractory use is most common.
- Function: Extends the life of chutes, hoppers, and pipelines by 10 to 20 times compared to steel, drastically reducing maintenance costs.
Insulating Fire Bricks (IFBs)
- Primary Advantage: Extremely Low Thermal Conductivity (K-value) and Low Heat Storage (Low Density).
- Structure: High porosity (trapped air pockets), lightweight, and easily cut.
- Function: Significantly reduces heat loss and saves energy, allowing for faster, energy-efficient furnace cycle times due to low thermal mass.
Typical Industries and Applications
| Product Type | Typical Industries Used |
| Wear-Resistant Tiles | Mining, Aggregate, Cement, Coal/Power Generation, Sinter Plants (Any abrasive material handling) |
| Insulating Fire Bricks (IFBs) | Glass, Ceramics, Heat Treating, Forging, Incinerators, and Chemical Process Furnaces |
Furnace Areas and Service Zones
- Wear-Resistant Tiles: Used in non-hot zones for abrasion protection: transfer points, cyclones, pipe elbows, bunkers, and charge areas.
- Insulating Fire Bricks (IFBs):
- Hot Face (Working Lining): Used in intermittent kilns/furnaces that require fast heat-up and cool-down cycles.
- Back-up Insulation: Used behind heavy refractory bricks to maximize energy efficiency and reduce cold face temperature.
Key Data Sheet Properties to Consider
- For Wear-Resistant Tiles: Focus on Bulk Density (BD), Mohs Hardness, and Wear Loss (%).
- For Insulating Fire Bricks (IFBs):
- Maximum Service Temperature: The limit of safe operation.
- Thermal Conductivity: Crucial. A lower value indicates better insulation/energy savings.
- Cold Crushing Strength (CCS): Must be adequate to support the lightweight structure.
- Classification Temperature: Used to designate the IFB grade (e.g., K-23, K-26).
Technical Guidance: When selling Ceramic Tiles, clarify the application: are they for Wear Protection (high-density Al2O3) or Insulation (low-density IFBs)? IFBs offer the maximum energy saving possible for a brick product but must never be used in high-wear or high-slag zones.

❓ Frequently Asked Questions (FAQ)
Question | Elaborated Answer |
Q: What is the Refractoriness Under Load (RUL) of your refractories? | A: Refractoriness Under Load (RUL) is a critical property that defines the maximum temperature our materials can withstand while under compressive stress before deforming (softening). Since we offer a wide range of materials—from Alumina-Silicate Bricks to high-performance Silicon Carbide Bricks—the RUL varies significantly. For specific product data, please refer to the product data sheet or submit a quote request for the material you are interested in. |
Q: Where are the Rabatec refractories and materials produced? | A: Our products are primarily sourced from specialized manufacturing plants in China. Crucially, these facilities have all undergone rigorous audits and achieved comprehensive ISO certifications (Quality, Environment, and Safety), ensuring that production adheres to the highest global standards for consistency and performance. |
Q: What refractory materials does the company offer? | A: We supply a comprehensive portfolio of advanced refractory solutions, including: Shaped Products: Alumina & Silica Bricks, Basic & Specialized Bricks (e.g., Magnesia), SiC & Structural Ceramics, and Precast Shapes. Monolithic Products: Refractory Castables, Mixes & Mortars. Insulation: Insulation Fibre and High-Performance Insulation Products. |
Q: How should I choose the appropriate refractory material for my application? | A: Selecting the correct refractory is paramount to process efficiency. The choice depends on three key factors: 1. Operating Environment: Maximum process temperature and thermal cycling (shock). 2. Chemical Attack: Type of slag, molten metal, or corrosive gas being handled (acidic, neutral, or basic). 3. Mechanical Stress: Abrasion, erosion, and static load requirements. We recommend utilizing our detailed refractory solutions service to consult with our engineers for an optimized, application-specific recommendation. |
Q: Which monolithic material should I choose when patching an existing lining? | A: For patching and minor repairs, the ideal monolithic material depends on the parent lining material, the patching depth, and the need for a rapid return to service. Common choices include: Refractory Mortars & Mixes (for minor joints/surfaces) or Plastic Refractories (for areas requiring physical compaction). Always choose a patch material chemically compatible with the existing lining to ensure proper bonding and service life. |
Q: Can I receive product samples before placing a major order? | A: Yes. We gladly provide product samples for your internal testing and validation purposes. This ensures you can confirm the quality, composition, and fit of the material—such as our Refractory Castables or Alumina-Silicate Bricks—in your specific operational environment before committing to a bulk purchase. |
Q: Do you provide certifications to verify material quality? | A: Absolutely. We provide product-related inspection certificates and quality assurance documentation upon request. This verifies that your order has passed all internal quality control checks and meets the required material specifications and industry standards. |
Q: What measures are taken for product protection during transport? | A: We ensure quick, reliable transport by using robust, industrial packaging that strictly follows industry standards. This includes high-strength palletization, heavy-duty strapping, and weather-resistant wrapping to protect fragile items like bricks and mixes from corner chipping, mechanical damage, and moisture during transit. |
