Az alumínium-oxid rugalmasabb, mint a szilícium-karbid, mint fúvóanyag, mivel szívó- és közvetlen nyomású rendszerekkel egyaránt működik, és egyenletes felületet eredményez keményebb fémek, például acél fúvásakor. A szilícium-karbid élesebb és keményebb is, mint az alumínium-oxid, de törékeny, keskeny alakja gyorsabban kopik, ami ...
Selecting the ideal blasting media can help operations achieve a sleek, professional finish. Aluminum oxide is often chosen for stripping, cleaning, and polishing metal and wood surfaces. Silicon carbide may be the superior option when working with tougher materials that require higher tensile strength and nonmetallic surfaces, making this article’s comparison between both grains the …
Reaction bonded silicon carbide (RB SiC) is an ideal material for near net forming processes such as pressing, injection molding and extrusion. Produced by infiltrating porous compacts with liquid silicon which results in reaction between carbon and silicon to form more SiC and hold initial particles together, creating near net forms with greater yields. Reaction …
No matter if it is used for grinding off rust off metal or prepping for welding, an abrasive wheel is sure to make the task go more efficiently. When selecting your wheel it is important to consider factors like grain size, grit and bond type. Abrasive wheels are constructed using powdered abrasive grains held together …

Kiln shelves serve as the support surfaces upon which ceramic ware is placed in a kiln and may be made of cordierite, alumina or nitride-bonded silicon carbide. Selecting the appropriate material for kiln furniture components is an essential decision for any user of a kiln, and silicon carbide has proven itself as an outstanding material …
Silicon carbide is an extremely hard and durable non-oxide ceramic, distinguished by its layered crystal structure containing four carbon and two silicon atoms in primary coordination tetrahedra. At least 70 different forms, or polytypes exist of silicon carbide. Modern applications of graphite include abrasive applications, melting furnace refractories and production lines for producing float glass …
