Benefits

VANTAGETM
Forming Clay

  • Designed to produce increased strength and plasticity in plastic forming and extrusion operations.
  • Ideal for blunging into slurries which are to be filter pressed and extruded or for conversion to spray dried granulate.
  • Able to withstand the rigours of automated processing and handling without cracking or deformation.

CERASIL®
Ceramic Grade Silica Flour

  • Reduce shrinkage during drying
  • Develop a lattice-like structure that strengthens the body while providing an exit for evolved gasses
  • Decrease thermal expansion and improve the glaze-to-body fit for greater craze resistance

MAXUM®
Ceramic Grade Sodium Feldspar

  • Provide a consistently uniform source of alumina to speed the transition into the glassy phase during firing
  • Low iron and high reflectance in Maxum help to produce ultra white bodies or bright, vivid colours without the need for opacifiers or additional enhancers
  • Regulate the glaze melt viscosity for a smoother, more even glaze surface

QUANTUM®
Ceramic Grade Potassium Feldspar

  • Provide a consistently uniform source of alumina to speed the transition into the glassy phase
  • Provide a higher total alkali contribution to strengthen and stabilise over a wide firing range
  • Improve hardness, durability, modulus of rupture and other critical mechanical properties in all ceramics

SPECTRUM®
Nepheline Syenite

  • Excellent stability in melting properties over a wide firing range
  • Increase tensile strength and abrasion resistance
  • Higher in Alumina and more alkaline than most feldspars

STARCAST®
Glaze and Casting Kaolin

  • Improve casting rate and deflocculant response in traditional, automated and pressure cast applications
  • Provide excellent suspension properties, stable viscosity and improved plasticity
  • Suitable for traditional and highly automated casting applications
