Our production of high purity and stability of yttrium zirconium oxide board, based on alumina substrates as the main body of high-performance products. It can be widely used in chip inductors, ceramic capacitors, because of its long life, non-sintered products produced with the reaction product does not affect the electrical properties. And Japan and Taiwan, compared to similar-quality products has obvious price advantage, it has been well-known enterprises of all types-line recognition. We can produce according to customer needs all kinds of different sizes with different specifications of products, providing complete product specifications, SGS environmental reports, ISO9000 quality system certification and MSDS.
