Yellow tungsten oxide Tungsten oxide (yellow) is a yellow crystalline powder.
Tungstic acid Tungstic acid is a very fine-grained, yellow powder with a very narrow particle size distribution.
Sodium tungstate Sodium tungstate is a white crystalline powder.

Support for specific technical applications

Depending on the specific battery material and processing method involved, we develop our tungsten products with a focus on customers and specific attention to use in high-performance battery materials.

Alongside close ties with our customers, we also work to establish and maintain cooperative relationships with leading research institutes such as the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW). This allows us to identify new trends emerging on the fast-paced battery market early on and optimize our products to meet these demands.
