If the tin source is anhydrous, very Htde volatile tin tetrahaUde is formed. If the mole ratio of halogen to tin is less than 4-to-l or if there is no halogen present, yet flame retardancy is observed, condensed-phase activity is assumed. The only suppHer of tin flame retardants is Alcan Inc. The price in 1992 was 7.70/kg. 

The principal producers of aluminum trifluoride in North America are Alcan, Alcoa, and AUiedSignal. It is also produced in other countries, eg, France, Mexico, Norway, Italy, Tunisia, and Japan. Total worldwide production of aluminum trifluoride in 1990 was 400,000 metric tons and the price was 1100/t. In 1993, because of excess recovery of fluorine values, use of energy efficient smelters, and the worldwide economic climate, the price was down to 750/t. 

Canada, the United States, and South America are the principal exporters of cryoHte and Russia and Europe import cryoHte. Primary producers in North America are Alcan, Alcoa, and Reynolds Aluminum. The 1993 price of recovered-grade cryoHte, which has as impurity, was 400/t, and of... 

K AIE 20, has emerged as a highly efficient, noncorrosive, and nonhazardous flux for brazing aluminum parts of heat exchangers. Nocolok 100 Flux (Alcan Aluminum Corp.) developed by Alcan (Aluminum Co. of Canada) has been the first commercial product. Its use and mechanistic aspects of the associated brazing process have been weU documented (33—37).

Alcan Aluminum and Columbia Falls Aluminum acquired 50% each of ARCO Aluminum ia 1985. Formerly iucluded with ConsoHdated and Revere. 

Shaped products used for adsorbent purposes are generally less sophisticated and therefore less expensive than catalytic products. In 1985, it was reported that 10,000 t/yr of activated alumina adsorbents were produced in the United States. North American producers of Bayer process-based activated aluminas include Alcoa, La Roche (formerly Kaiser Chemicals), Discovery, and Alcan. Gel-based activated aluminas are produced by La Roche, Vista, and several of the major catalyst manufacturers. In Europe, principal sources of supply are Rhc ne-Poulenc and Condea.

The Alcan process has been used commercially by Osaka Titanium Co. ia Amagasaki, Japan. Multipolar ceUs of 1000 t/yr capacity are ia operation. Energy consumption is about 9.5—10 kWh/kg of magnesium metal (111).

A consolidated picture of the different processes for the production of aluminum is shown in Figure 6.25. There are altogether four processes (i) Alcan process (ii) Toth process (iii) Alcoa process and (iv) Bayer process. 

The Alcan (Aluminum Company of Canada) process is based on the direct reduction of the ore to form an aluminum alloy (by carbothermic reduction carried out in an electric arc furnace at about 2000 °C). The alloy is then reacted with aluminum trichloride at 1300 °C to form aluminum monochloride. The monochloride is next contacted with molten droplets of aluminum to form aluminum metal the trichloride is regenerated for further reaction ...
