It’s boiler slag, which is a recycled product from coal-burning plants. When coal is “fired” at over 2,500 degrees, it melts and produces a by-product called slag. When the slag is cooled through a process called vitrification, it solidifies, forming sharp, angular granules in a variety of sizes. We reclaim this slag, dry it, crush it, screen it, and then size the remaining granules into seven different grades.
Iron silicate is a by-product of a metal refining process. During smelting, slag floats on the molten metal. Slag that is quenched in water produces angular granules which are stockpiled to be processed into abrasive granules.
It simply works better. It’s the low-cost product you want with the high efficiency you need to get any job done quickly. It’s also a recycled product, so you can feel good about going green.
Black Diamond abrasive products are by far the toughest, most effective “one-time” use blasting media available. Not to mention, cost-effective. Compare the efficiency and power of our low-dusting products with any other abrasive media and Black Diamond wins every time. We also offer more grade sizes than anyone else in the industry, meaning you have more options to better achieve the target profile and finish.
Absolutely! Our abrasive products are recycled and even meet drinking water standards. Black Diamond abrasive products are the safer alternative to sand because they contain less than 0.1% free crystalline silica and are low dusting and chemically inert. Additional certifications and recognitions can be seen here.
Of course! To do so, you need to blast in a clean environment with a screening process in place to reclaim the granules. Your screens must be consistent with the grade of the abrasive product you’re using.

The best applications are outdoor uses where you need a quick-cutting media. Black Diamond abrasive products are also ideal in situations where you need the power of a recyclable product without hassle and prep work.
You can blast nearly any surface. With our selection of seven grades, you have the product for any job. Our range of products is fit to prepare the surfaces for heavy duty applications or to brush new surfaces clean of light dust, rust, or enamels for a smooth finish.

Yes, Black Diamond abrasives can be used in any blaster with the proper nozzle sizing.
It depends on the surface you wish to prepare and the blasting equipment you plan to use. We carry seven different grades of abrasives products that range from our most coarse product, 1040, to our finest product, 4080. View a complete listing of our coal slag grades and iron silicate grades as well as the recommended uses, mil profile, and preferred nozzle size for each product.
