Phase Equilibria, Crystal Structures, and Dielectric Anomaly in the BaZrO 3 -CaZrO 3 System

November 1, 2003
Author(s)
Igor Levin, T G. Amos, S M. Bell, L Farber, Robert S. Roth, Terrell A. Vanderah, B H. Toby
Phase equilibria in the (1-x)BaZrO 3-xCaZrO 3 system were analyzed using a combination of X-ray and neutron powder diffraction, and transmission electron microscopy. The proposed phase diagram features two extended two-phase fields containing mixtures of a

Inhibition of Premixed Methane-Air Flames by Fluoromethanes

April 1, 1996
Author(s)
Gregory T. Linteris, L Truett
This paper presents the first calculations and measurements of the burning velocity of premixed hydrocarbon flames inhibited by the three one-carbon fluorinated species CH2F2, CF3H, and CF4. The chemistry of these agents is expected to be similar to that
