Four ceramic systems cover the duties Vintel@Ceramics builds for: high purity, high strength, high-temperature service, corrosion and wear resistance, and electrical insulation. The grade is selected against the operating conditions rather than fixed by a single stock specification.
Comparison
Read the table down a column for one material system, or across a row to see which system carries the duty furthest.
| Material system | Al₂O₃ | ZrO₂ | SiC | Si₃N₄ |
|---|---|---|---|---|
| Purity | HIGH | HIGH | HIGH | HIGH |
| Flexural strength | HIGH | VERY HIGH | HIGH | VERY HIGH |
| Max service temperature | HIGH | MODERATE | VERY HIGH | VERY HIGH |
| Thermal shock resistance | MODERATE | MODERATE | VERY HIGH | VERY HIGH |
| Corrosion resistance | HIGH | HIGH | VERY HIGH | HIGH |
| Wear resistance | HIGH | VERY HIGH | VERY HIGH | HIGH |
| Electrical insulation | EXCELLENT | HIGH | MODERATE | HIGH |
| Typical part forms | Widest range | Wear-led range | Thermal duty | Dynamic duty |
Ratings express relative performance across the four Vintel@Ceramics material systems, not absolute property values. Exact purity, tolerance and surface finish are specified per grade. Request the material data sheet for your application.
In detail
Al₂O₃
High purity · High strength · Electrical insulation
Alumina is the workhorse of industrial ceramics: high purity and high strength with excellent electrical insulation, and it holds its shape and surface at the temperatures used in photovoltaic, instrumentation and power equipment.
Material detailsZrO₂
Toughness · Wear resistance · Fine surface finish
Zirconia combines high strength with wear resistance and a fine ground finish, which makes it the material of choice where a ceramic part has to survive abrasion, impact and repeated mechanical duty.
Material detailsSiC
Extreme temperature · Thermal shock · Abrasion
Silicon carbide is selected for the most demanding thermal and abrasive duty: high-temperature service, thermal shock and aggressive wear, where few other materials hold their properties.
Material detailsSi₃N₄
Strength at temperature · Thermal shock · Light weight
Silicon nitride keeps high strength at elevated temperature together with thermal shock resistance and low weight, which suits moving parts, high-speed duty and thermally cycled equipment.
