pencarian hr ni psl substate (silicone or silicone dioxcide??) masih belum jumpa lg... bes juga belajar kimia ni... mana satu nk guna ni?? sumber: google silicon Silicon is a chemical element with the symbol Si on the periodic table of elements. It is most commonly found on earth combined with oxygen forming Silicon Dioxide, sand. Silicon can be broken apart from the oxygen and purified to create polycrystalline silicon or single crystal silicon which is a hard and brittle semi-metal used to manufacture solar cells as well as electron devices and circuits used in television sets, cell phones, computers...etc. silicone Silicone, on the other hand, is any number of polymers that include silicon together with carbon, hydrogen, oxygen and other chemical elements typically forming a pliable, rubber like substance used as a sealant around windows, adhesive, and for augmented body parts (implants) among other uses. silicone dioxcide one part silicon to every two parts oxygen.
