How to Choose the Right Ceramic Materials for Your Application
Ceramic materials—especially technical ceramics—have become indispensable in modern industry due to their outstanding properties. These materials are widely used across sectors such as electronics, mechanical systems, metallurgy, energy, aerospace, chemicals, and medical equipment, often replacing metals in demanding applications.
Unlike traditional ceramics, technical ceramics are engineered for superior performance and durability, offering excellent hardness, high-temperature resistance, corrosion resistance, and electrical insulation. This article introduces six technical ceramic materials offered by Mascera, including alumina ceramics, zirconia ceramics, and silicon nitride ceramics, and explains how to choose the right material for your needs.
Key Performance Indicators of Technical Ceramics
When selecting ceramic materials, consider the following key properties:
Hardness: High hardness ensures excellent wear resistance and shape retention under load.
Temperature Resistance: Some ceramics withstand temperatures above 1600°C, ideal for furnaces, heat shields, and thermocouple protection.
Corrosion Resistance: Ceramics resist chemical attack, making them suitable for chemical processing, pumps, and marine applications.
Mechanical Strength: Zirconia ceramics offer exceptional toughness, suitable for load-bearing structures.
Electrical Insulation: Most technical ceramics are excellent insulators, used in electronic substrates, insulators, and power modules.
