SiC

Silicon Carbide Ceramics

Silicon carbide for the most demanding thermal and abrasive duty: very high service temperature, thermal shock and aggressive wear.

Advanced Industrial Ceramics

Silicon carbide is reserved for the toughest conditions in the catalogue. It holds its properties at very high service temperature, resists thermal shock and stands up to abrasive and corrosive media where other ceramics and most metals fall short.

It is the material behind high-temperature tubes and crucibles, abrasive-duty plates and nozzles, and wear parts that have to hold their geometry through repeated thermal cycling.

Part forms we make in this material

Each form page carries the parts we have photographed, the tolerances we work to, and what we ask before quoting.

FORM 01

Ceramic Tubes

Straight and stepped tubes for high-temperature processing, insulation and conveying duty, supplied as-fired or precision ground.

FORM 02

Ceramic Crucibles

Shallow and deep crucibles for melting, sintering and high-temperature containment where contamination must stay out of the process.

FORM 04

Ceramic Plates

Flat plates and substrates for insulation, support and wear surfaces, held to flatness and thickness requirements.

FORM 05

Ceramic Rings

Precision-ground rings used as sealing, guiding and insulating elements, with the bore, wall and chamfer finished to drawing.

FORM 06

Ceramic Nozzles

Nozzles and orifices for abrasive, corrosive and high-temperature flow, where a metal nozzle would wear out or contaminate the stream.

FORM 08

Ceramic Wear Parts

Wear liners, guides, bushes and contact parts that extend service life where metal surfaces abrade, gall or corrode.

FORM 09

Custom Precision Components

Engineered parts built from your drawing: grade selection, geometry, tolerance, surface finish and inspection defined with your application.

FORM 12

Ceramic Structural Parts

Machined blocks, brackets and spacers that locate, support or isolate inside equipment, built to your drawing and inspection points.

What is defined with you before production

  • Geometry and wall section defined against the thermal cycle.
  • Support and seating faces specified for high-temperature assemblies.
  • Surface finish selected for abrasive or flow duty.
  • Grade selected for the peak temperature and the medium in contact.
