Recently, abrasives have been used in a greater variety of industries. Abrasives are used in a variety of industries like manufacturing, housing, aerospace, and others. The industry outlook for abrasives is positive due to increased activity in these industries, and the demand for abrasives is also growing. For those who are new to abrasives, here is a quick guide to understand the basics.

Natural Vs Synthetic Abrasives

Abrasives are used for polishing, grinding, sharpening, drilling, buffing, cutting, or honing a surface, and can be either natural or synthetic. Natural synthetics can be mined and processed and include diamond, corundum, and emery. On the other hand, synthetic abrasives are produced by processing raw materials or chemical precursors. Due to the high demand of abrasives across different industries, today, most abrasives in use are produced synthetically. Some abrasive minerals, such as zirconia alumina, are natural but are more expensive to acquire, therefore, synthetic stones are used industrially instead.

What Improves the Quality and Usefulness of Abrasives

Shape
The shape of the particle affects the performance of abrasives. It could affect the rate of stock removal or level of subsurface damage. However, some applications require unusual shapes. A primary descriptor of shape in abrasives is the aspect ratio, but it is not relevant in all kinds of abrasives. For example, the aspect ratio may be useful in fused alumina but misleading in others.

Heat
Heat is applied to abrasives in an attempt to enhance toughness. High or low heat may often be applied to brown aluminum oxide. High heat enhances toughness of the abrasive more than low heat. Although to improve cleanliness and capillarity of the grain, low heat may be preferable and relevant. High heat-treated abrasives are typically used in grinding wheels, specialized industrial applications and coated abrasives.

Surface Treatments
To enhance the bonding of the abrasive grains, saline treatments may typically be used. Such grains are applicable for use in grinding wheels and industrial use. For coated abrasives, there are many types of coatings which can be applied that enhance the electrostatic properties of the grain. This improves the abrasives projection when sandpaper is made. To improve bonding of grains for sandpaper application, iron oxide coatings may be used.
