Generally speaking, the raw materials should have no impurities. This means that they should not be mixed with other substances; otherwise, they are the processed materials instead of raw materials. Besides, they should be a good basis that would help improve the performance of the finished products. That is to say, what properties required in the finished products should wholly or at least partially be seen in raw materials. In addition to the intrinsic properties, the production technology would also play a role. It may even maximize the properties of the raw materials and improve the performance of passive network equipment .
