The present invention relates to materials and more particularly to particulate materials suitable for use as thermal spraying powders. There is disclosed a process for the preparation of a particulate material suitable for use as a thermal spraying powder which includes treating a mixture comprising an inorganic substance as a major component (as defined in the Specification) and a sol to gel the sol thereby to form an intermediate material comprising inorganic substance and gel and heating the intermediate material. One example of thermal spraying is plasma spraying.

Materials

In a sodium-sulphur cell having a solid electrolyte separating sodium from a cathodic region containing sulphur/polysulphides in a graphite felt, a cathode current collector is formed of an aluminium substrate on which is an interstrate layer of nickel-chromium alloy covered by a coating of titanium oxide or other electronically conductive oxide intrinsically inert to the cathodic reactant.
