Abstract

Materials of construction resistant to fluorine and acid fluorides comprise at least a matrix of a self-hardening cupric phosphate cement and/or a self-hardening thermoplastic aluminium phosphate cement. The cement is prepared by mixing phosphoric acid with powdered cupric oxide and/or aluminium oxide, the rate of hardening being controlled by pre-calcining the oxides. Apparatus for handling fluorine or acid fluorides, e.g. the electrolytic cell described in Specification 668,465, [Group XXXVI], may be made of, or coated with, the compositions. A non-conductive filler, e.g. rouge, calcium fluoride or polytetrafluoroethylene, may be included in the composition; conductive fillers, e.g. carbon, graphite or fluorine resistant metals, may also be added.ALSO:A composition resistant to fluorine and acid fluorides comprises at least a matrix of a self-hardening cupric phosphate cement and/or a self-hardening thermoplastic aluminium phosphate cement. The composition may also include non-conductive fillers, e.g. rouge, calcium fluoride or polytetrafluoroethylene, or conductive fillers, e.g., carbon, graphite or fluorine-resistant metals. Parts of apparatus for handling fluorine are made of, coated with or joined by the composition.
