Magnesium Oxide - Cleaning Instructions

Magnesium Oxide Single Crystals absorb moisture which will damage the surface of the crystals.  To protect the polish from moisture, ESPI packages the material under dry argon gas.

To clean the crystals, soak in alcohol, preferably methanol. The crystals should be held in this solution until ready for film growth. Attempt to use the crystals as soon as possible after cleaning. Avoid steam cleaning, water based cleaning agents and moisture. Use only soft lens gauze to wipe the crystal surface.

We are constantly striving to improve our products. If you have suggestions in this regard we would welcome any and all comments.
