Business Combination Disclosure [Text Block] | Note 15 Purchase of assets On December 16, 2016, we purchased certain assets formerly owned by Tantaline A/S of Nordborg, Denmark through our wholly owned subsidiary, CVD Materials Corporation. Formed in 2007, as a spin off from The Danfoss Group, Tantaline A/S established itself as a leader in the commercialization of tantalum treated parts for corrosion resistance. We have now established in Nordborg a new and wholly owned CVD subsidiary operating under the name Tantaline CVD Aps (“Tantaline”).
