MIRACRYSTAR^®️

Single Crystal Magnesium Oxide Substrate

MIRACRYSTAR^® is the largest crystal MgO that has the purity of 99.9%. This single crystal MgO exhibits excellent characteristics, providing infinite possibilities as essential materials for various applications.

Features

Forming a large, single-crystal magnesium oxide had been considered difficult, given the material’s extremely high vapor pressure and the high melting point required.
Yet, as a specialized manufacturer in magnesium oxide, in 1968 Tateho achieved the world’s first success in commercializing large single crystals, utilizing its proprietary electro-fused and crystallization technologies.
Today, Tateho continues to produce the world’s largest single-crystal magnesium oxide with a purity of 99.9% or more ― MIRACRYSTAR^®.
This single crystal MgO "MIRACRYSTAR^®" exhibits excellent characteristics, providing infinite possibilities as an essential materials for various applications.
