There are several types of sand that are commonly used in the casting process. The most widely used is silica sand, composed primarily of silicon dioxide. This type of sand is valued for its high melting point, making it suitable for casting metals at high temperatures. The grain size and shape of the silica sand can significantly affect the quality of the final casting. Other types of sand include chromite sand, zircon sand, and olivine sand, each possessing unique properties that can be beneficial for specific casting applications.
