Sintered Stone and Quartz Stone are both popular high-end materials used in modern interior design, especially for kitchen countertops, walls, and furniture surfaces. However, they differ significantly in composition, manufacturing process, durability, and applications. Here’s a detailed comparison:
| Feature | Sintered Stone | Quartz Stone |
|---|---|---|
| Main Composition | Natural minerals (quartz, feldspar, oxides, etc.) | 90%-95% natural quartz + 5%-10% resin |
| Manufacturing Process | High-pressure compression + sintering at 1200-1400°C | Artificially engineered stone bonded with resin |
| Density & Hardness | High density, Mohs hardness 7-8 (similar to granite) | Slightly lower, Mohs hardness 6-7 (harder than marble, but softer than sintered stone) |
| Water Absorption | <0.1% (almost waterproof) | 0.02%-0.1% (also water-resistant) |
✅ Conclusion: Sintered stone is produced using advanced sintering technology, making it harder, more heat-resistant, and denser. Quartz stone is engineered with resin and quartz powder, making it slightly softer but still very durable.
| Feature | Sintered Stone | Quartz Stone |
|---|---|---|
| Color & Patterns | Mimics natural stone (marble, granite, etc.) | Wide range of colors, more uniform but looks more "artificial" |
| Size | Can be made in large slabs (up to 3200×1600mm) | Typically smaller (up to 3000×1400mm) |
| Thickness | 12mm | 15mm, 20mm |
✅ Conclusion: Sintered stone is better for large seamless applications, while quartz stone offers more variety in color but may appear less natural.
| Feature | Sintered Stone | Quartz Stone |
|---|---|---|
| Scratch Resistance | ✅ Mohs hardness 7-8, highly scratch-resistant | ✅ Mohs hardness 6-7, still scratch-resistant but slightly softer |
| Stain Resistance | ✅ Extremely stain-resistant, non-porous surface | ✅ Stain-resistant, but resin components may absorb stains over time |
| Heat Resistance | ✅ Can withstand high temperatures up to 1200°C | ❌ Not heat-resistant; exposure to temperatures over 150°C can cause burns or discoloration |
| UV Resistance | ✅ UV-resistant, suitable for outdoor use | ❌ Not UV-resistant; prolonged sun exposure can cause yellowing |
✅ Conclusion: Sintered stone is more resistant to heat, scratches, stains, and UV exposure, making it suitable for both indoor and outdoor applications. Quartz stone, while durable, can discolor or get damaged by extreme heat.
| Usage Scenario | Sintered Stone | Quartz Stone |
|---|---|---|
| Kitchen Countertops | ✅ Ideal, highly heat-resistant, scratch-resistant, stain-resistant | ✅ Suitable, but cannot withstand direct heat from hot pots |
| Bathroom Countertops | ✅ Great choice, waterproof and moisture-resistant | ✅ Suitable, but avoid exposure to harsh chemicals |
| Floors & Walls | ✅ Suitable, can be used in large slabs with fewer joints | ❌ Not commonly used for flooring (can be slippery) |
| Furniture Surfaces | ✅ Ideal for tables, cabinets, and vanities | ✅ Suitable, but thickness is usually limited |
| Outdoor Use | ✅ Excellent, UV-resistant and weatherproof | ❌ Not recommended, may turn yellow over time with sun exposure |
✅ Conclusion: Sintered stone is ideal for countertops, walls, furniture surfaces, and even outdoor use, whereas quartz stone is mainly used for indoor countertops and bathroom vanities.
