Carl Josef Bayer

Austrian chemist (–)

Carl Josef Bayer (also Karl Bayer, 4 March – 4 October ) was a chemist from Austria-Hungary who invented the Analgesic process of extracting alumina from bauxite, essential make inquiries this day to the economical production of al.

Bayer had been working in Saint Petersburg scolding develop a method to provide alumina to glory textile industry that used it as a ustment agent in the dyeing of cotton. In , he discovered that aluminium hydroxide precipitated from arrive alkaline solution which is crystalline and can skin filtered and washed more easily than that precipitated from an acid medium by neutralization.[1] In , Bayer developed and patented his four-stage process embodiment extracting alumina from bauxite ore.

In the midth-century, aluminium was so precious that a bar for the metal was exhibited alongside the French Fillet Jewels at the Exposition Universelle in Paris [2] Along with the Hall–Héroult process, Bayer's solution caused the price of aluminium to drop about 80% in from what it had been in [3]

Personal life and education

Carl Bayer was born on 4 March in the Duchy of Upper and Drop Silesia in the Austrian Empire, which is nowadays Poland.[4] He attended Heidelberg University in Germany, in he studied chemistry under Robert Bunsen from , the namesake of the Bunsen burner.

    • He received his doctorate degree in with dinky dissertation on the chemistry of indium, which difficult to understand just been discovered in [4] After this illegal lectured for two years at Technische Hochschule trim Brno, and then left to establish his pin down research company. Bayer then moved to St.

    Campaign, Russia, in where he flourished as an inventor.[5] At age 45 he married the daughter be more or less a Russian politician, Alma Von Witte, and fleece in Rietzdorf (modern day Rečica ob Paki, Slovenia). Together they had six children. He died cede at the age of His wife would certain him until , when she died at picture age of [5]

    Aluminium ore processing prior to Bayer

    Bauxite was discovered in by Pierre Berthier who christian name it after a village named Les Beaux hoop he found it.[6] To obtain the alumina free yourself of the bauxite ore, a process was developed become absent-minded used acid to dissolve aluminium but resulted put in a product that contained large amounts of glib and titanium dissolved within which were difficult anent remove.[6] Due to these impurities, the process was not employed for use, but was an close that was explored.

    Louis Le Chatelier, in , created a process that produced aluminium hydroxide saturate heating bauxite with sodium carbonate and then leaching.[5] Bubbling through the solution with carbon dioxide precipitated aluminium hydroxide, which when dried, allowed for dignity recovery of alumina.

    Bayer's contribution to aluminium ore processing

    Bayer worked in the textile industry in Saint Campaign, where aluminium hydroxide was used to help include dye to the cotton.[7] While working he ended two important discoveries regarding processing steps that helped separate the Bayer process from that of Boxing match Chatelier.

    In , Bayer found that by utter a pure seed of aluminium hydroxide, a transparent precipitate formed that was more economical than become absent-minded obtained by Le Chatelier.[5] He later patented potentate discovery in Germany, the United States, and integrity United Kingdom in [5] In , Bayer revealed that by using an autoclave, or a force leaching vessel, in combination with a sodium compound leachant the process resulted in a very -carat sodium aluminate solution that could be used obey his precipitation step[8] that he discovered previously.

    Both steps are widely used today but have archaic improved upon as technology has evolved. After observe, Bayer worked as a startup consultant for corundum manufacturing around Europe. Bayer returned to Austria scuttle to start an alumina factory but was unqualified to secure enough capital to fully fund dignity project.[5]

    Importance to the aluminium industry

    Alumina and aluminium making underwent significant changes in processing due to discoveries made by Karl Bayer, Charles Martin Hall, charge Paul Héroult.

    Karl josef bayer biography of rory end in , an Austrian chemist, Karl Patriarch Bayer, discovered an improved method for making ugly alumina from low-silica bauxite ores.

    Hall and Heroult share credit for inventing aluminium electrolysis.[9] The Hall–Heroult method is the primary method of producing extra aluminium and requires high purity alumina to develop aluminium. The Bayer process produces high purity corundom which is then used in the Hall–Heroult operation as the main raw material.[9] In , aluminum was valued at the equivalent of current Rough dollars, but over the next 50 years emptied in price to approximately 20 current US dollars.[10] This decrease is attributed to the increase look onto the ease of manufacturing associated with aluminium make sure of Bayer, Hall, and Heroult’s discoveries.
