SOLVAY Ernest (1838-1922) was a
Belgian industrial chemist who began working in the chemical industry at the age
of 21. He devised several methods for purifying gases, but he is best known for
the development of a commercially valuable ammonia-soda process for producing
sodium carbonate and his invention of the Solvay carbonating tower (in which an
ammonia-salt solution could be mixed with carbon dioxide). In 1861, he took out
his first patent for soda production, in 1863 he set up his first factory, and by
1890 Solvay had established companies in several foreign countries. By 1900, 95%
of a greatly increased world production of soda came from the Solvay process.
The exhibition "Flanders Technology International" showed
many applications of physics.
|The first "Physics Olympiad" was held in Warsaw (1967). The 21th in 1990 (Groningen- the Netherlands) and, as you can see on the stamps above, the 33rd was hosted in Indonesia and the 38th in Iran..|
