Silicon has long been considered an attractive material for batteries due to its ability to contain 10 times more lithium ions than graphite; however, one drawback with silicon lies in its 3x volume expansion upon taking in lithium ions. Mechanical stresses result in damage to the solid electrolyte interface (SEI), shortening its lifespan. Solving this challenge is key to unlocking demand for battery-powered cars, drones and consumer electronics. Higher Energy Density Silicon carbide is an extremely wide-bandgap material with the potential to significantly increase battery energy density. It can handle much higher voltages than silicon, as well as temperatures that would cause silicon to expand under pressure. Furthermore, silicon carbide …

Silicon carbide (SiC) is a wide bandgap semiconductor found naturally as moissanite jewels and mass produced as powder or crystal to be used as an abrasive. SiC Schottky Diodes are ideal for power conversion applications, providing advantages over conventional silicon diodes. Read on to discover their key benefits:. Faster switching speed Silicon unipolar diodes have an upper limit of 150 V due to their high on-state resistance and leakage current; in comparison, SiC Schottky diodes offer much lower specific on-state resistance and much higher blocking voltage, providing faster switching speed in power electronics devices. SiC is known for its wide bandgap that allows transistors to easily handle higher electric fields, …

Silicon carbide and gallium nitride (GaN) represent the next wave of power semiconductors. These WBG materials are revolutionizing industry with increased efficiency, smaller size and lower costs associated with high performance power electronics. Politicians should instead place greater focus on strengthening global gallium supply chains to ensure the United States remains competitive on an international market. This will allow companies from different nations to come together and keep costs competitive for future GaN epitaxy production here at home. Wider Bandgap Band gaps in semiconductor materials measure the energy required for electrons and holes to switch from their valence band to conduction band, or vice versa. Silicon has an energy requirement …

Silicon carbide abrasive material is widely employed in modern lapidary. Additionally, silicon carbide serves as an integral raw material in manufacturing advanced ceramics and refractories. Carborundum occurs naturally only in trace amounts as the mineral moissanite, so its commercial production began with Edward Acheson in 1891. Hardness Silicon carbide is one of the hardest natural compounds available, boasting an exceptional Mohs hardness of 13. This exceptional hardness enables silicon carbide to resist abrasion, wear and other mechanical stresses; in turn its strength and stiffness make it ideal for components in demanding environments with high mechanical loads and temperatures. Silicon carbide’s hardness can be attributed to its unique crystal structure: tightly …

Silicon carbide provides the ultimate grip enhancement. When applied, its surface texture creates greater friction between your hands and gun frame for enhanced control and greater comfort. We provide various textures including 120 grit (black), which feels similar to 120 grit sandpaper and is suitable for competition use. In addition, we also offer 60 grit texture which is less aggressive and ideal for beginners. Increased Friction Grip strength is one of the primary factors determining accuracy for shooters. There are various techniques used to increase grip friction, including stippling guns and applying grip tape or creams such as pro grip. While these solutions work temporarily, over extended use they wear …

Silicon carbide is an incredible material with remarkable physical, thermal, and chemical properties that make it suitable for use in demanding environments. Edward Goodrich Acheson first synthesized graphite in 1891 during an experiment to produce synthetic diamonds, and it remains one of the hardest naturally occurring substances today. Hardness Silicon carbide’s hardness is one of its key properties and results from the covalent bonding between carbon and silicon atoms within its crystal lattice, giving this material exceptional shear and impact resistance. Furthermore, its relatively lower density compared to diamond and tungsten carbide makes handling it for cutting or grinding simple. SiC hardness can be measured using Mohs, Vickers and Brinell …
