Incandescent tungsten actively interacts with atmospheric gas, the most modern methods of chemical protection are used. The tungsten billet (block) is obtained by powder metallurgy. Next, the staff is heated and unrolled on a forging rotary machine to a thin sheet. After converting the sheet into foil, rolling can continue without additional heating. The foil has a very smooth surface, and the surface oxides are removed by hot sodium hydroxide solution or by calcination (t ° 1000 ° C) in a hydrogen atmosphere. The quality of production is controlled at all stages of production.
