Required properties of BDD matrix
Small thermal expansion coefficient,Good electrical conductivity;
No phase change within the deposition temperature range;
Good chemical stability of itself and carbidesHiah resistance to h ydrogen embrittlement;
Not too expensive (economical).
Advantages of niobium based materials
①Power saving: low resistance, low power consumption, can significantly reducethe operating costs of equipment.
②Corrosion resistance: high chemical stability, strong acid and alkali resistance.
③Easy to connect: low contact resistance, which is beneficial for simplifying theelectrolytic cell.
④Not easy to break: high strength, not easy to break during use, and easy totransport.
⑤|mproving mass transfer: easy to form various shapes such as mesh and wave.which is beneficial for improving the mass transfer process.
⑥Space saving: thin plates can be used to reduce costs and increase theavailable space of the electrolytic cell.
