Subsequently, coatings to minimize oxidation were investigated for high temperature applications of SKD legs in air. In this study, two oxidebased materials (Al 2 O 3 and MgO), and a SiC ceramic were applied to the SKD as antioxidation coating materials. These materials are thermally stable at 400–600 °C and have low thermal conductivities,
The World is Running Out of Sand. The littleknown exploitation of this seemingly infinite resource could wreak political and environmental havoc. Aurora Torres, Jianguo "Jack" Liu, Jodi Brandt
The percentage of silicon in the silica sand was calculated using the formula. % silicon = Weight of silicon x 100 Weight of silica sand The silicon product was placed in a platinum crucible weighed and put in a furnace at 1100oc for 30 minutes after which it was removed allowed to cool in a discicator and weighed again.
When the reaction is complete, allow the mixture to cool (about five minutes) and with the aid of a spatula pour the products into about 50 cm 3 of 2 mol dm –3 hydrochloric acid. After a few minutes the pops will cease and grey silicon powder, possibly with a little unreacted sand, will be left on the bottom of the beaker. Pour off the acid

Complex chemical and physical processes are required to ensure that silicon crystals meet the high production standards that apply to chips to convert silica sand to silicon. The sand is combined with carbon and heated to an extremely high temperature to remove the oxygen. Several other steps are required to create the finished product,
