1954 R. B. Sosman in Science CXIX. 738/2 I have sought and obtained permission from Coes and Keat, both of whom are now at the Research Laboratories of the Norton Company in Worcester, Mass., to propose names for the new phases—namely, coesite for the phase produced at 35,000 atm., and keatite for the phase produced hydrothermally.

1962 Times 1 June 8/6 It is impossible for coesite to be formed at pressures less than about 20,000 times that of the atmosphere... The Norton Company has been supporting the high-pressure research..in the hope..of making diamonds in the laboratory.
