Key Properties and Benefits of Ceramic Sand

High Refractoriness:

Ceramic sand can withstand very high temperatures, making it suitable for casting various metals, including steel and iron.
Spherical Shape:

The spherical shape of ceramic sand particles provides excellent flowability and packing, which leads to better mold filling and improved surface finish of castings.
Low Thermal Expansion:

Ceramic sand's low thermal expansion minimizes defects like cracking and warping in castings, particularly in high-temperature applications.
High Reclamation Rate:

It can be recycled and reused multiple times, reducing material costs and waste.
Reduced Binder Usage:

In some foundry processes, ceramic sand requires less binder than silica sand, leading to lower gas evolution during casting and improved casting quality.
Versatility:

Ceramic sand can be used in various foundry processes, including no-bake molding, resin coated sand cores, and lost foam casting.
Good Permeability and Flowability:

This allows for efficient venting of gases during casting and easier mold filling.

Applications in foundries:

No-Bake Processes:Improves sand strength, reduces binder levels, and increases reclamation yields.
Resin Coated Sand (RCS) Cores:Enhances flowability, reduces expansion and gas evolution.
Sodium Silicate Systems:Reduces binder consumption, enhances shake-out properties, and minimizes defects like penetration and sand burn-on.
Lost Foam Casting:Improves flowability, filling, and permeability.
