How is silicon made from sand
Did you know?
WebSilicon is made from sand, and it is the second most abundant element on earth after oxygen. Silicon wafers are made using a type of sand called silica sand, which is made of silicon dioxide. The sand is melted and cast in the form of a large cylinder called an ‘ingot’. This ingot is then sliced into thin wafers. The nano scale WebGlass samples were made from extracted silica sand and laboratory grade silica sand (99.99%). For making low melting point glass Na 2 CO 3, K 2 CO 3 and Li 2 B 4 O 7 were used as fluxing agent. To make a firm glass object three batches were taken from each of the two different amount of batches. These batches are shown in table 1.
