Typically, Silicon Carbide is produced using the Acheson process which involves heating silica sand and carbon to high temperatures in an Acheson graphite resistance furnace. It can be formed as a fine powder or a bonded mass that must be crushed and milled before it can be used as a powder feedstock. Once the Silicon Carbide is in a powder
3. These silicon carbide balls provide very large amount of energy to the material powder and the powder then get crushed. This process of ball milling is done approximately 100 to 150 hrs to get uniform fine powder. 4. Ball milling is a mechanical process and thus all the structural and chemical changes are produced by mechanical energy.

Data are provided for the specific surface, x-ray patterns, and infrared spectra. It is shown that milling kinetics are described best of all by an exponential relationship and that milling of silicon carbide powder is accompanied by changes in
Grinding/ Ball Milling:Abrasive media are applied for ball milling or grinding down of a solid material or powder into smaller pieces or finer powders. The material being ground and the media (ceramic bead, hard metal shot, carbide balls or other ball shaped media) are filled in the ball mill for rotating, grinding and mixing by mechanical forces.

Silicon carbide (SiC) nanoparticles were produced by a carbothermic reduction of nano and micro size silica (SiO 2) with graphite at relatively low temperature of 1450 °C for 1 h. The particle size of silica and milling time were important parameters determining the rate of carbothermic reduction and size and morphology of SiC particles produced.
Silicon Carbide Ball Applications – Silicon carbide is an ideal material for sealing rings and bearings. – Silicon carbide is frequently used in semiconductor and coating industries. – Special bearings and pumps, electric switches and sensors, medical instruments.

Starting materials used for milling were silicon and graphite with 99.5 and 99% purity respectively. Steel balls of diameter 6 and 12 mm were used for milling. When setting up a milling experiment, one has to select the number and size of the milling balls and the total mass of the powder.
Silicon Carbide Balls are very high-cost grinding media that are used for milling the same materials (silicon carbide ball to mill silicon carbide materials) to avoid contamination. They are available in 5mm, 10mm, 12mm, 15mm, and 20mm sizes. Also, customized size is available. Applications of Silicon Carbide Grinding Media:

Zirconium diboride (ZrB 2) and silicon carbide (SiC) composites have long been of interest since it was observed that ZrB 2 improved the thermal shock resistance of SiC. However, processing of these materials can be difficult due to high and different sintering temperatures and differences in the thermodynamic stability of each material.
Sintered Silicon Carbide SiSiC, like Saint-Gobain’s proprietary Hexoloy ® brand, is produced at extremely high temperatures (~2,000°C) in inert atmospheres using a range of forming methodologies, including dry-pressing and extrusion. Reaction bonded, or siliconized, silicon carbide is formed using a porous carbon feedstock and molten silicon via additive forming, casting or extrusion.
