What is the preparation method of Chromium Trifluoride?

To make Chromium trifluoride (chromium trifluoride), the ancient method, multi-step legal. First take chromium ore, often chromite, and soda ash co-melting, the reaction is as follows: $4FeCr_2O_4 + 8Na_2CO_3 + 7O_2\ stackrel {high temperature }{=\!=\!=} 8Na_2CrO_4 + 2Fe_2O_3 + 8CO_2 $. After melting, soak in water to obtain sodium chromate solution, add acid to adjust its pH, so that chromate is converted to dichromate, $2CrO_4 ^ {2 - } + 2 H ^ +\ rightleftharpoons Cr_2O_7 ^ {2 - } + H_2O $.
Then reduce dichromate to trivalent chromium ions with a reducing agent, such as sulfur and charcoal. If reduced with sulfur, the reaction is: $8Na_2Cr_2O_7 + 3S + 16H_2O = 8Cr (OH) _3\ downarrow + 3Na_2SO_4 + 10NaOH $. To obtain chromium hydroxide precipitation, after filtration, add hydrofluoric acid to dissolve, $Cr (OH) _3 + 3HF = CrF_3 + 3H_2O $. After evaporation, crystallization and drying, chromium trifluoride can be obtained.
Today's method also uses metal chromium to react directly with fluorine gas. This reaction is violent and requires strict temperature control, pressure control and gas flow rate in a special reactor. $2Cr + 3F_2\ stackrel {certain conditions }{=\!=\!=} 2CrF_3 $. The product obtained by the method has high purity, but fluorine is highly toxic and corrosive, which requires strict equipment and operation.
