Emery vs. Sand — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on May 7, 2024
Emery is a naturally occurring abrasive composed of corundum and magnetite, commonly used in polishing and grinding, while sand is a naturally formed granular material primarily composed of silica and used in construction and as an abrasive.

Key Differences
Emery, primarily composed of corundum, is highly abrasive and frequently used for grinding and polishing metals, gemstones, and glass. Sand, on the other hand, consists of finely ground rock, primarily silica, and finds wide application in construction, glassmaking, and as a general abrasive.
Emery's hardness makes it particularly effective in industrial applications like cutting and sharpening, whereas sand's grain size and texture make it versatile for casting molds, creating concrete, and smoothing surfaces.
Emery is often processed into emery cloth or paper for precision polishing, while sand is available in various grades based on particle size, used across industries from landscaping to water filtration.
Emery is more specialized in abrasive applications due to its hardness and mineral composition. In contrast, sand is a broader material, utilized not only as an abrasive but also for creating construction materials like concrete and mortar.
