Adsorbed gaseous species and elements in a carbon (C) powder and a graphite crucible are reduced by way of a vacuum and an elevated temperature sufficient to cause reduction. A wall and at least one end of an interior of the crucible is lined with C powder purified in the above manner. An Si+C mixture is formed with C powder purified in the above manner and Si powder or granules.
Effect of Raw Material Mixtures. The reactivity of different quartz and silicon carbide sources has been studied. The SiC charge material is a mixture of hexagonal and rhombohedral polytypes. In contrast with Filsinger and Bourrie and Presser and Nickel, the two polytypes show different reactivity with silica (Figure 12). Hexagonal silicon ...

There is no doubt or mistake about it that an eraser is a student's best friend! It gives you the chance of undoing something that you have done and then try again. You get innumerable chances of correcting yourself if you have an eraser and hence, even when the adults sit to make a draft about something they are not sure, they use a pencil and eraser.
