A powder suitable for flame spraying which is a composition of an admixture of particles, 20-40% by volume of the particles being an alloy such as a nickel base alloy or cobalt base alloy, each containing aluminium and chromium and the balance of the composition are hollow glass particles, each hollow glass particle being coated with a nickel base alloy or cobalt base alloy, each containing aluminium and chromium. The powder, when flame sprayed, is effective as a thermal barrier which is resistant to thermal shock and oxidation.
