Foundry Ceramic Sand

Short Description:

Foundry Ceramic Sand, also named as ceramsite, cerabeads, ceramcast, is good artificial spherical grain shape which is made from calcined bauxite . Its main content is aluminum oxide and Silicon oxide. Ceramic sand, has much better properties than that of silica sand to gain a better performance in foundry. It has high refractoriness, little thermal expansion, good angular coefficient, excellent flowability, High resistance to wear, crush and thermal shock, high reclamation rate.

Foundry Ceramic Sand - the perfect solution for all your foundry needs. This innovative product is also known as ceramsite, cerabeads, or ceramcast, and is made from calcined bauxite giving it an excellent spherical grain shape. With its high content of aluminum oxide and silicon oxide, Ceramic Sand boasts superior properties compared to conventional silica sand.

Ceramic Sand offers numerous advantages over silica sand. Firstly, it has a much higher refractoriness, making it ideal for use in high-temperature applications. It also has a low thermal expansion, ensuring that it maintains the sand mold or core shape and consistency even during extreme heat.

In addition to its impressive strength, Ceramic Sand offers excellent flowability - this ensures that it can be easily molded and shaped during the casting process. Furthermore, Ceramic Sand has a high resistance to wear, crush, and thermal shock, making it the ideal choice for all kinds of casting applications.

Another key advantage of using Foundry Ceramic Sand is that it has a high reclamation rate, meaning that it can be easily reused in the casting process. This, in turn, helps to reduce waste and minimize costs.

Overall, Foundry Ceramic Sand is a must-have for any foundry looking to improve their casting performance. With its excellent properties and superior strength, it offers a significant advantage over traditional silica sand.
