Abstract
A fluorine compatible apparatus, incorporating numerous safety features, is described. This apparatus has been used to make accurate determinations of the PVT properties of gaseous and liquid fluorine from 53.5 K (the triple point) to 300 K and to pressures of 20 MN/m2 (3000 psi). The experimental method is similar to the isochoric one used previously in this laboratory for oxygen and hydrogen. A limited testing program, to determine the suitability of various materials for use with high pressure fluorine, is described and the test results tabulated. Some general fabrication techniques, suitable for construction of fluorine handling apparatus, are discussed.Keywords
