About us



We’re a Leading Company in Zirconium Products.

We’ve won high praise as one of a handful of companies anywhere in the world specializing in integrated production technologies for manufacturing zirconium compounds from zirconium ores.
We plan to continue pursuing research and development efforts to meet the ever-increasing demand for diverse, advanced products and to offer these products on a timely basis to satisfy various customers.
DKK America Materials, Inc. is located in the U.S. to more ably serve customers in North America who seek a “local” zirconia supplier.

 Our products are used across a wide range of industries that include not only automotive and industrial catalyst, and electronic fields, but also the fine ceramics field, where high strength, high precision, and high toughness are in demand.

Our company will retain its role as a driving force behind technologies, and novel materials for a new era.
