Mixtures carbon-filled materials

Figure 22 shows a practical large anode. The anode started as a rough cylinder of YBD carbon about 20 cm in diameter and 120 cm long. A central cavity 10 cm in diameter and 110 cm deep was machined in as shown. The pores in the carbon were filled with a commercial epoxy material using standard techniques. (The material was a mixture of... 

The electrolyte has a particular structure. A mixture of LiA102 and alkali carbonates (typically >50 vol%) is hot pressed (about 5000 psi) at temperatures slightly below the melting point of the carbonate salts. In this way, a porous matrix support material of ceramic particles (LiA102) is formed that contains a capillary network filled with molten electrolyte. The ceramic material in the electrolyte structure represents a mechanical resistance which does not participate in the electrical or electrochemical processes. The prepared electrolyte has a thickness of 1-2 mm, and it is very difficult to produce it in large shapes. 

Bulkiness The specific bulk volume, the reciprocal of bulk density, is often called bulkiness or bulk. It is an important consideration in the packaging and filling of powders for tablet production. The bulk density of calcium carbonate can vary from 0.1 to 1.3, and the lightest or bulkiest type would require a container about 13 times larger than the heaviest type. Bulkiness increases with a decrease in particle size. In a mixture of materials of different sizes, however, the smaller particles sift between the larger ones and tend to reduce the bulkiness.
