Technical Ceramics (Customized to Customer Specifications)

Application Area

Stahl-Contor offers wear parts that are protected with ceramics. These components are particularly advantageous where fine, aggressive particles at high speeds are responsible for wear.

Benefits

Components protected with technical ceramics can be used at operating temperatures up to 1,500°C and are highly resistant to weathering effects, acids (except hydrofluoric acid), and alkalies. They provide excellent protection, particularly when fine particles at high velocities cause wear. This type of wear is commonly found in pipes, elbows, hoppers, etc.
 

Product Offer

We offer three different types of wear parts with technical ceramics:

DURZALT 40: Made from high-quality basalt derived from special lava stone, DURZALT 40 is suitable for temperatures up to 350°C. In thicknesses of 18-25mm, it is used as internal protection for pipes (minimum internal pipe diameter: 50mm), and in 30mm thickness, it is used in elbows (minimum elbow diameter: 50mm). The service life of DURZALT 40 is six to seven times longer than steel in suitable applications.

DURHART 200: Composed of a mixture of high-purity metal oxides, DURHART 200 is melted in an electric furnace at temperatures exceeding 1,800°C. It can be used at temperatures up to 1,500°C. Available in 25-50mm thickness as tiles or as internal protection for pipes (minimum internal pipe diameter: 50mm) and in 30mm thickness for elbows (minimum elbow diameter: 50mm). The service life of DURHART 200 is three to five times longer than DURZALT 40 in appropriate applications.

ALDUR 240: Made from a complex powder blend, the powder is shaped and compressed under extremely high pressure. After processing, ALDUR 240 is fired in a furnace at 1,500°C to achieve an extremely compact structure with high density and hardness. It can be used at temperatures up to 1,200°C. ALDUR 240 is at the top of our materials for protection against sliding wear.

Parts protected with technical ceramics are custom-made based on customer specifications.
