Wear resistant ceramic is a high-hardness ceramic material designed to resist mechanical wear. Compared with ordinary structural ceramics, these materials are selected primarily for their ability to withstand abrasive contact and maintain dimensional stability during long-term operation.
Common industrial grades include:
Among these materials, alumina is one of the most widely used choices for general abrasion protection because it combines high hardness, good chemical stability, and relatively competitive cost.
For applications involving severe impact, elevated temperature, or specific chemical conditions, other ceramic compositions may be more suitable.
Abrasion Resistant Ceramics Material Options
Alumina Wear Resistant Ceramic
Alumina ceramics are widely used for chutes, hoppers, pipelines, cyclones, separators, and material transfer equipment.
Typical alumina contents include approximately 90%, 92%, 95%, and 99% Al₂O₃, depending on the required performance.
Higher alumina content generally provides higher hardness and improved wear resistance, but material selection should also consider impact loading and installation conditions.
ZTA Wear Resistant Ceramic
Zirconia Toughened Alumina combines an alumina matrix with zirconia to improve toughness compared with conventional alumina.
ZTA can be considered where both abrasion resistance and improved resistance to mechanical impact are required.
It is particularly useful when ordinary alumina tiles are exposed to repeated impact or vibration.
Silicon Carbide Wear Ceramic
Silicon carbide provides high hardness, good thermal conductivity, excellent thermal shock resistance, and strong performance at elevated temperatures.
It is suitable for selected high-temperature and highly abrasive applications, including certain kiln, furnace, metallurgical, and mineral-processing environments.
Zirconia Ceramic
Zirconia offers significantly higher fracture toughness than conventional alumina ceramics.
It is generally selected for applications where mechanical toughness, precision, and resistance to repeated impact are more important than the lowest possible material cost.
Wear Resistant Ceramic for Different Industries
Mining Industry
Mining equipment is continuously exposed to abrasive ore, rock, sand, and mineral particles.
Wear resistant ceramic products can be used for:
Cement Industry
Cement production involves large quantities of raw materials, clinker, cement, and other abrasive particles.
Abrasion resistant ceramics can protect:
Steel Industry
Steel plants handle abrasive raw materials such as iron ore, coke, sinter, and slag.
Ceramic wear protection can be used in:
For elevated-temperature locations, the ceramic grade and bonding method must be selected according to the actual operating temperature.
Power Generation
Coal, ash, and mineral particles can produce significant abrasion in material handling equipment.
Wear resistant ceramic liners can be applied to:
Ceramic and Refractory Industry
Ceramic production involves the handling of powders, granules, and fired materials.
Ceramic wear liners can protect equipment where continuous particle movement causes localized abrasion.
