What is claimed is: 1. A perforating device for use in completing a well, comprising: (a) a casing; (b) an explosive charge; and (c) a shaped liner enclosing the explosive charge in the casing; wherein at least one of the shaped liner and the casing comprises a composition of barite and metal. 2

What is claimed is: 1. A perforating device for use in completing a well, comprising: (a) a casing; (b) an explosive charge; and (c) a shaped liner enclosing the explosive charge in the casing; wherein at least one of the shaped liner and the casing comprises a composition of barite and metal. 2. The perforating device according to claim 1, wherein both the shaped liner and the casing comprise a composition of barite and metal. 3. The perforating device according to claim 1, wherein at least one of the shaped liner and the casing further comprises steel. 4. The perforating device according to claim 1, wherein the casing comprises a sufficient amount of barite so that the casing disintegrates into a powder upon detonation of the explosive charge. 5. The perforating device according to claim 4, wherein the powder attenuates shock caused by detonation of the explosive charge. 6. The perforating device according to claim 1, wherein at least one of the shaped liner and the casing further comprises a binder. 7. The perforating device according to claim 6, wherein the binder is a cured epoxy powder. 8. The perforating device according to claim 6, wherein the binder is a thermoset epoxy resin. 9. The perforating device according to claim 6, wherein the binder is a polymeric material. 10. The perforating device according to claim 6, wherein the binder is a wax. 11. The perforating device according to claim 6, wherein the liner comprises tin material. 12. The perforating device according to claim 6, wherein the binder is flash-cured. 13. The perforating device according to claim 6, wherein the binder is sintered. 14. The perforating device according to claim 1, comprising at least about 25% barite, remainder steel and a binder. 15. The perforating device according to claim 1, comprising at least about 30% barite, remainder steel and a binder. 16. The perforating device according to claim 1, comprising at least about 70% barite, remainder steel and a binder. 17. The perforating device according to claim 1, wherein the at least one of the shaped liner and the casing further comprising barite has a density of about 3.0-7.5 grams/cc. 18. A method of making a perforating device for use in completing a well, comprising: (a) providing an explosive charge; (b) forming at least one of a casing and a liner out of a material that comprises a composition of barite and metal; and (c) enclosing the explosive charge between at least one of the casing and the liner. 19. The method of claim 18, comprising the step of forming both the casing and the liner out of a material that comprises a composition of barite and metal. 20. The method of claim 18, wherein the material further comprises steel. 21. The method of claim 18, wherein the material comprises at least about 25% barite, the remainder comprising steel and a binder. 22. The method of claim 18, wherein the material has a density in the range of 3.0-7.5 grams/cc. 23. The method of claim 18, wherein the material further comprises a binder. 24. The method of claim 18, wherein forming comprises the step of pressing the material into a forming mold to form at least one of the casing and the liner. 25. The method of claim 24, wherein forming further comprises the step of heating the mold to a temperature of about 300-400° F. in the mold. 26. The method of claim 25, wherein forming further comprises the step of cooling the mold to room temperature. 27. A perforating device for use in completing a well, comprising: (a) a casing; (b) an explosive charge; and (c) a shaped liner enclosing the explosive charge in the casing; wherein at least one of the shaped liner and the casing comprises a composition of: (a) barite; (b) steel; and (c) a binder; wherein the composition has a density within a range of 3.0-7.5 grams/cc.
