Heraeus

No. 63591

The German Imperial Patent Office granted Patent No. 63591 in 1891, the first in the history of Heraeus, for a process of adding gold to sheet platinum. Until the beginning of the 20th century, sulfuric acid was produced by the lead chamber process and heated and concentrated in platinum vessels. Heraeus developed vessels made of a mixture of gold and platinum that were even more resistant to the aggressive acid than pure platinum, reducing platinum losses tenfold.

99.99999 %

Quartz glass (SiO2) is one of the purest technical materials used in industry today. Natural quartz sand contains 99.99% SiO2. Heraeus uses complex processes to purify the raw material to 99.999%-pure natural quartz sand. Even higher quality quartz glass with a purity of 99.99999% is produced from synthetic raw materials. This quartz glass is needed for such purposes as manufacturing lens blanks for the production of microchips.

1856

Platinum and high-melting platinum alloys are melted at Heraeus Precious Metals in induction furnaces, cast into bars and then processed further. Platinum itself melts at 1769°C, and is inseparable from the history of Heraeus. Using an oxyhydrogen blowpipe in 1856, company founder Wilhelm Carl Heraeus was the first to obtain the precious material in industrially useful quantities. This pioneering achievement has since been followed by a stream of countless innovative developments.

1 million hip joint prostheses

Every year, over a million hip joint prostheses are implanted throughout the world. A routine operation that is nevertheless associated with a certain risk of infection. Heraeus Medical utilizes its many years of expertise in infection prophylaxis in cemented arthroplasty, and is developing new products like bone cements containing antibiotics to actively counter the risks of infection – whether in prevention, as support of treatment.

Heraeus Materials Technology

60 million tons

60 million tons of nitric acid is produced each year, most of it for fertilizers. Since the beginning of the 20th century, nitric acid has been obtained by burning ammonium over catalytic gauzes of fine platinum wires. Heraeus has driven the development of the catalyst significantly. Due to the continuous development of catalyst systems, production of nitric acid has steadily increased over the last few decades. Today’s producers are using gauzes made with platinum-rhodium alloys with diameters of up to six meters.

Heraeus Electro-Nite

1750 °C

More than one billion tons of steel are produced around the world every year. To ensure the

quality of molten metals, their temperature and chemical composition must be measured at regular intervals. Lance-shaped immersion sensors measure these parameters rapidly and accurately. Even temperatures as high as 1750°C are no ‘burning’ issue for the sensors. Heraeus Electro-Nite designs these customized sensors, combining them with common measuring methods.

90 seconds

A carbon infrared oven from Heraeus is curing decorative coatings on glass bottles in only 90 seconds. A significant time saving, compared to conventional hot air ovens which would need 25 minutes. A carbon infrared oven has helped a British company to achieve significantly faster curing of organic paint sprayed onto to decorative perfume bottles. The new oven eliminated a bottle neck in the production line.
