What is Rock Tuler Grit?
Rock tuler grit is a man-made silicon carbide abrasive. It is inexpensive, extremely hard, and crushes into sharp, angular particles. These properties make it an effective abrasive for cutting, shaping, and smoothing rocks and other hard materials.
Silicon – expert written, user friendly element information
Silicon carbide, more commonly called carborundum, is extremely hard and is used in abrasives. Silica (SiO 2) in sand and minerals in clay is used to make concrete and bricks. Silica, as sand, is also the main constituent of glass. Pure, crystalline silicon
Silicon weight to volume conversion - Aqua-Calc
Silicon weighs 2.33 gram per cubic centimeter or 2 330 kilogram per cubic meter, i.e. density of silicon is equal to 2 330 kg/m³; at 25 C (77 F or 298.15K) at standard atmospheric pressure.
