Applications of Magnesium Oxide Wafers Substrates

MgO Single Crystal Substrate products are used widely for HTSC (high-temperature superconductor) thin film coatings applications worldwide. There is also a growing amount of interest in using these substrates, because of their economic cost, for other applications that previously would not have justified the higher cost of MgO, such as for use as substrates for the III to V elements.
