ACCUCAST HT intermediate-density, high-temperature ceramic casting media

ACCUCAST HT ceramic media is produced with a unique combination of consistent thermal, physical and chemical properties that provide economic and performance advantages compared to various sand products used for metal casting production.

The ACCUCAST HT product is engineered to withstand high pouring temperatures and long-term heat loads that come with making very large steel and iron castings while minimizing defects.


  • High refractoriness
  • Low linear thermal expansion
  • Spherical shape with high hardness
  • High permeability
  • ​Chemically inert and non-hazardous, contains no crytalline silica


  • Withstands high temperature pours of various metal castings
  • Increases dimensional precision and ability to pour complex parts
  • Reduces expansion-related defects
  • Reduces casting cleaning times
  • Increases production, reduces particle breakdown and supports recycle use
  • Reduces gas related defects and associated costs
  • ​Lowers environmental, safety and health concerns
