When was aluminum first refined?

Answer 1

When was aluminum paint first used?

As copied....The gelling of oil solutions by aluminum soaps was known since at least the late 19th century but the use of aluminum stearate to alter the properties of paint did not come into use until much later. Church in 1901 mentions the use of "linoleate or oleate of alumina" to prevent the "subsidence" of vermilion in tubes (Church 1901), a comment not found in the 1890 edition (Church 1890). No further mention is made of this or similar materials until decades later even in Gardner's test protocols of 1911, the first of a series of books which would become the industry standard for paint analysis (Gardner 1911).

Aluminum stearate has been used to help suspend pigments in oil to prevent separation, to reduce the amount of oil needed to wet the pigment, and/or to increase the body of the paint by forming a gel with the oil thereby requiring less pigment.

Research into the use of aluminum and zinc stearates as aids to grinding pigments and preventing settling or separation of pigment from vehicle (medium) resulted in a patent application in 1920 and issue of U.S. patent #1,421, 625 on July 23, 1922 to Clarence A. Ward.

Answer 2

In ancient times aluminium salts where used for wound treatment.

Aluminium as a metal was first produced in an impure form in 1825 by Hans Christian Ørsted and in 1827 as a pure metal by Friedrich Wöhler. As it was very difficult to extract from its ore, in the middle 19th century it was considered more precious than silver, gold, or platinum and thus used for decoration, for example in the apex block (the largest piece of aluminum cast to that time) of the capstone of the the Washington Monument (it was placed there in 1884 so every Americanwould have a chance to see this new and unbelievably expensive metal). In 1886 a new process for extracting aluminum was perfected that dropped the price so low that the apex block was now completely worthless.

Answer 4

It was used in the past to make strong and steady buildings, used for cans, foil and also to sell to get money

Answer 5

Aluminium was discovered by Oersted in 1825.
The industral production began in 1888.

Answer 6

Aluminum was first refined in 1825 by Danish physicist Hans Christian Oersted. However, it was not produced in pure form until 1827 by German chemist Friedrich Wöhler.
