Industrial Ceramics
Raw Materials for High-Performing, Highly Engineered Ceramics
Industrial ceramics, also known as technical ceramics, are specialized materials built to perform exceptionally well in extreme environments where standard metals and plastics typically fail. Their extreme hardness, high heat tolerance and resistance to corrosion allow them to create highly durable components that safely power modern systems. You can find these versatile materials in a wide variety of everyday and specialized applications, ranging from household appliances and consumer electronics to medical implants and automotive parts. They are also essential for heavy industrial manufacturing, serving as vital components in cutting tools, kilns and structural refractories.
Industrial Ceramics Manufacturing Challenges
Covia provides the highest quality minerals, such as ball clay and kaolin clay, which are essential ingredients for producing engineered industrial ceramics. By combining their extensive technical expertise with a collaborative approach, Covia can evaluate body formulas in the lab and help manufacturers optimize their ceramic processes. Ultimately, partnering with Covia ensures excellent product quality, increased production efficiency and reliable delivery times for all your advanced ceramic needs.
Manufacturing industrial ceramics presents several complex variables and challenges that can drastically alter the final product’s performance if not meticulously managed.
Common technical needs include:
Particle size management to simplify the manufacturing process.
Controlled firing temperature and atmosphere for stable, consistent sintering.
Minimal raw material impurities to maintain the ceramic’s high-temperature performance and corrosion resistance.
Adaptable formulations for different production methods, from dry pressing to extrusion and slip casting.
Balanced stabilizers and sintering aids to achieve the necessary toughness, phase stability and densification.
Strictly controlled firing processes to mitigate shrinkage and warping.

Materials and Formulas
Industrial ceramic pieces require the perfect blend of refined oxide or non-oxide compounds, dry pressing under high pressure and sintering in extreme heat. The right formulation depends on the finished product requirements. For example, ceramic insulators, which provide reliable electrical insulation in power transmission, electronic devices and heavy industrial equipment, must exhibit high electrical resistance, durability and thermal stability.
Kaolin and ball clays are an excellent source of alumina (Al2O3), one of the most widely used industrial ceramic materials. Kaolins are typically 90 percent kaolinite (higher alumina content), while ball clays may contain 40 to 70 percent kaolinite (lower alumina content). Lower-purity alumina bodies are often used in wear and refractory applications, which are less demanding. Higher-purity alumina is more common in electrical components, semiconductor-related hardware and tighter-tolerance wear parts.
