Ceramic Sand

Ceramic Sand


The selected raw materials to make CERABEADS® artificial sand are fired at a high temperature, making the structure dense.


CERABEADS® artificial sand is made of mullite crystals with an extremely stable quality.


It is made by firing spherical granules, not by crushing.


CERABEADS® artificial sand has the following advantageous chemical and physical properties:

  • Uniform component composition
  • Stable grain size distribution and air permeability
  • High refractoriness (SK37, 1825°C)
  • High resistance to wear, crush and thermal shock
  • Little thermal expansion
  • Excellent fluidity and filling efficiency owing to being spherical


Major Applications

  • As foundry sand
    • Sand for loop system
    • As spot sand, face sand for sand casting
    • Sand for applications where high accuracy in dimension and surface smoothness are required
    • As reusable lime sand
    • Sand for rapid prototyping and Additive Manufacturing (AM)
  • As setter for high-temperature furnaces
  • As media for fluidized bed
  • As ceramic filters
  • Others

"Prior to our relationship with Weaver Materiel, we were purchasing riser sleeves direct from the OEM. As a stocking distributor, Weaver typically is able to deliver same or next day. OEM lead times averaged three to four weeks. With Weaver, I've been able to reduce my working inventory by about 40%."

“Ashland Foundry & Machine Works and Weatherly Casting are grateful for the partnership in our working relationship with Weaver Materials.  Weaver has helped us maintain pricing and avoid increases in a volatile market.  Weaver has always kept us in supply of material when markets dictated shortages/allocation status.  If Weaver was not in our vendor pool daily production ability would have been negatively impacted.  Weaver is also technically able to review our foundry processes and make suggestions to either achieve a cost savings or process improvement.  I am looking forward to a continued collaboration between the Weaver team and my locations.”
