A pile of copper powder weighs 1 kg. The particles are spherical in shape and the sizes vary, forming a statistical distribution as follows: 23% of the particles by weight are 0.0254 mm, 56% are 0.0508 mm, and the rest are 0.0762 mm. Given this distribution, determine the total surface area of all the particles in the pile.

A process that is used to make high-quality technical ceramics is called sintering (see images below). During the early stage of sintering, individual particles are attached by the formation of necks. How do the so-called necks form? (In other words, what processes are occurring that cause the necks to form?)

In powder processing, a cylinder with a diameter of 2 inches and a height of 10 inches is to be made from fine copper powders. A single-action press is used for compaction. If the average density of the green product is 7 g/cm3 at the bottom half of the cylinder, estimate the compaction pressure at the punch surface. Assume no friction between the powders. The coefficient of friction between particles and containers is 0.2.
