There are two types of crystals ‒ single crystal and polycrystalline ‒ which differ depending on the orientation of grains that make up the crystal.
Single crystal materials are those in which the grains are aligned in a uniform pattern. Diamonds are a perfect example. Diamonds, which are hard and clear, are made of carbon, but so is pencil lead, which is soft and black. The base material is the same, but their characteristics differ dramatically depending on the crystalline state.
There has been an understanding in the industry that various material characteristics could be improved by adopting single crystal materials, but practical applications have been hindered by engineering difficulties and prohibitive costs. KRYSTAL overcame these issues by applying original single crystal technologies, successfully creating single crystal materials that were considered unattainable in the past.
We are now able to manufacture even more products, and respond to an even wider range of customer needs.

From President

KRYSTAL Inc. was established through the spinoff of the Film Forming Division at Advanced Material Technologies, Inc., which has led the industry in the manufacture and sales of DLC film forming equipment and the development of high-performance PZT (lead zirconate titanate). In the development of MEMS materials, KRYSTAL was the first in the world to successfully create a single crystal form of PZT, which is used universally in MEMS applications, and has contributed to dramatic improvements in performance.
As a next step, we are currently developing materials for band-pass filters, which are used in mobile communications. With a passion for technological development, we will continue to develop a wide range of “single crystal” materials.
We look forward to your valued guidance and support.
