Compaction of ceramic powders is a forming technique for ceramics in which granular ceramic materials are made cohesive through mechanical densification, either by hot or cold pressing. The resulting green part must later be sintered in a kiln. The compaction process permits an efficient production of parts to close tolerances with low drying shrinkage. It can be used for parts ranging widely in size and shape, and for both technical and nontechnical ceramics. WebMar 7, 2024 · Dynamic compaction (DC) strengthens weak soils by controlled high- energy tamping (dropping a static weight from a defined height). The reaction of the soil during the treatment varies with soil type and energy input. Typically drop weights range from 6-20 ton dropped from heights up to 20m.
