Foundry sand can serve an array of purposes, whether you are in the manufacturing business and creating molds or in the machining business and stripping a piece of metal. Foundry sand can be completely natural or synthetic or even a hybrid mix with a little of both. One of the most preferred types of foundry sand is ceramic foundry sand, but some people who would benefit from using this unique form of aggregate do not know enough about it. Here is a look at some of the general questions you may have about foundry sand made with ceramic materials.
Is ceramic sand safe for use in outdoor applications?
Ceramic sand is safe for use in outdoor applications because it is environmentally safe and practical. The sand is created without the use of compounds like silica, which can be a contamination concern if they are spilled on the ground. Many industrial operations prefer ceramic foundry sand specifically because it is safe enough for use in outdoor applications without causing environmental concerns.
How well does ceramic sand stand up to tough usage?
Ceramic sand is surprisingly durable even though it is a common misconception that it breaks down easier during use. The rounded shape means it sustains a hard impact really well without breaking down, and it also stands up well to high-pressure applications. The misconception comes from that "ceramic" designation, which is often assumed to be highly breakable. While this may be true with large pieces of ceramic, tiny sand granules tend to be really tough and hard to break.
Does ceramic sand work well in applications involving heat?
Ceramic does not conduct heat as readily a lot of other types of sand made from synthetic materials like silica, and it thwarts heat better than something like zircon foundry sand. Therefore, it works well for applications that involve heat, whether you are doing a cast job on a piece of hot metal or something similar.
What is the difference between green sand and ceramic sand?
Green sand refers to sand that is good enough to be used in outdoor applications and does not harm the environment. Green sand stands up well but breaks down easily after years in a natural setting, and it does not contain chemicals that can cause issues with contamination. Ceramic sand fits all of these criteria, so it is actually often referred to as a form of green sand.
