Use the Indigo® SiC crystal model to show why the structure of silicon carbide gives it the hardness, durability, strength that makes it useful for grinding, polishing, and abrasives.
Silicon carbide (SiC) is one of the hardest synthetic materials known, second only to diamond. This makes it invaluable in grinding wheels, sandpapers, and cutting tools, where hardness and durability are essential. The Indigo® crystal lattice model helps students and professionals visualize the atomic arrangement that underpins SiC’s mechanical strength. By connecting structure to performance, the model supports learning in materials science, industrial chemistry, and geology, while offering context for why SiC remains a cornerstone of the abrasives industry.
Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years (scroll down to see "Skeletal (Orbit/Minit) and are compatible with every molecular model kit we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.
