Fused silica or fused quartz, is a glass powder made of amorphous silica. It is commonly used in the fiber optics and glass industries. Sieving fused silica can be a challenging process because typically fused silica is extremely fine, which by nature makes it harder to screen. The shape of fused silica determines what the best method of sieving is. Fused silica can be either angular or round and this is typically the most important factor when determining how to sieve fused silica.
Elcan has 2 different methods when it comes to sieving fused silica. The method of sieving relies on the shape of the fused silica particles. For angular fused silica, the Minox Tumbler screener is the most capable machine as it uses a gyratory motion to determine which angular particles pass through the mesh. For spherical fused silica, the hi-sifter can make separations down to 10um on this powder. For extremely fine separations down to 1 micron, the Elbow Jet Air Classifier is the way to go.
