The exothermic dissolution of calcium chloride is used in self-heating cans and heating pads. In the oil industry, calcium chloride is used to increase the density of solids-free brines. It is also used to provide inhibition of swelling clays in the water phase of invert emulsion drilling fluids. CaCl2 acts as flux material, decreasing the melting point, in the Davy process for the industrial production of sodium metal through the electrolysis of molten NaCl. Calcium chloride is also used in the production of activated charcoal. Calcium chloride can be used to precipitate fluoride ions from water as insoluble CaF2. Calcium chloride is also an ingredient used in ceramic slipware. It suspends clay particles so that they float within the solution, making it easier to use in a variety of slipcasting techniques. Calcium chloride dihydrate (20 percent by weight) dissolved in ethanol (95 percent ABV) has been used as a sterilant for male animals. The solution is injected into the testes of the animal. Within one month, necrosis of testicular tissue results in sterilization.Cocaine producers in Colombia import tons of calcium chloride to recover solvents that are on the INCB Red List and are more tightly controlled. Metal reduction flux
Similarly, CaCl2 is used as a flux and electrolyte in the FFC Cambridge electrolysis process for titanium production, where it ensures the proper exchange of calcium and oxygen ions between the electrodes. Hazards
Although non-toxic in small quantities when wet, the strongly hygroscopic properties of the non-hydrated salt present some hazards.
Specific therapy includes the use of  intravenous heparin and corticosteroids, and possibly plasma exchanges, intravenous immunoglobulin. As a disease associated with high morbidity and mortality, CAPS requires an aggressive multidisciplinary treatment strategy. The following treatments have been used in various combinations: anticoagulation, glucocorticoids, plasma exchange, cyclophosphamide, intravenous immunoglobulins, and anti-platelet agents. Additional steps may have to be taken to manage circulatory problems, kidney failure, and respiratory distress. Recent investigational treatment therapies include high doses of Rituxan (Rituximab) and eculizumab, which are both humanized monoclonal antibodies that target B cell malignancies and prevent C5 complement cleavage, respectively.
