An electrochemical technique has been used to measure the diffusion coefficient of hydrogen in palladium-copper and palladium-niobium alloys between 0 and 50ยฐC. The range of concentration for the copper and niobium additions was 0-lOat.?.,. For all experiments the hydrogen content was kept below 0.1
According to the phase diagram of lithium niobate (LN) a decomposition of congruently melting LN with segregation of a niobium rich phase LiNb 3 O 8 (L3N) has been observed. It occurs at the surface and at defects within the LN crystals at temperatures significantly higher than 300 C. L3N crystals g
The diffusion coetBcient of hydrogen in nickel has been determined at room temperature using a combination of electrochemical charging and measurements of the diffusion-elastic phenomenon. This technique has the advantage of allowing a determinatio.r of the dihtation of nickel due to interstitially
