Et püsida tipus peab firma eksportima oma väärtusi Euroopasse. Whenever lists of America's brightest and best are compiled 3M is guaranteed to feature. Whenever lists of America's brightest and best are drawn up 3M is listed. Millal iganes koostatakse nimekirju Ameerika säravamatest ja parimatest siis 3M on loetletud. 3M was born early this century as Minnesota Mining & Manufacturing. The mining soon ceased when the company's founders failed to dig up the corundum they had hoped to discover. So they turned to trading in sandpaper, a product that uses the abrasive corundum. From the beginning the company was forced to innovate or die. 3M was born early this century as Minnesota Mining & Manufacturing. The mining was interrupted when the company's founders didn't succeed in digging the corundum they had hoped to discover.

3M on parim kehastus ettevõtlikus Ameerikas. Et jääda tippu peab ettevõte eksportima oma tugevusi Euroopasse. Whenever lists of America's brightest and best are compiled 3M is guaranteed to feature. Millal iganes luuakse nimekirju Ameerika säravamatest ja parimatest siis 3M-i esinemine on seal garanteeritud. 3M was born early this century as Minnesota Mining & Manufacturing. The mining soon ceased when the company's founders failed to dig up the corundum they had hoped to discover. So they turned to trading in sandpaper, a product that uses the abrasive corundum. From the beginning the company was forced to innovate or die. 3M sündis selle sajandi alguses kui Minnesota Kaevandamine ja Tootmine. Kaevandamine peatati peagi, kui ettevõtte asutajad ebaõnnestusid korundumi väljakaevamisel, mida nad olid lootnud leida. Seega nad pöördusid liivapaberi tootmisele, toode milles kasutatakse abrasiivset korundumit
Mis on mineraalid ja kivimid? Mineraalid on kindla keemilise koostise ja enamasti kristallilise struktuuriga looduslikult esinevad anorgaanilised tahked ained. Kivimid on maakoort moodustavad mineraalide kogumid. Mõned kivimid, nagu kvartsiit (puhta kvartsi massid) ja marmor (puhta kaltsiidi massid) koosnevad põhiliselt ühest mineraalist. Enamik kivimeid koosneb siiski mitmest mineraalist. Korund / Corundum Koostis / struktuur Korund on alumiiniumoksiid (Al2O3). Korundi kristall on romboeedrilise sümmeetriaga (primitiivne rakk on romboeeder). Kui kvartsi (SiO 2) amorfne modifikatsioon kvartsklaas esineb nii loodulikult kui on saadav tehislikult, siis klaasi saamine alumiiniumoksiidist õnnestus alles äsja (A Rosenflanz et al. 2004 Nature 430 761). Omadused Puhas korund on värvusetu, tihedus 3,9 4,1, kõvadus 9 (teemandi järel
