cip patent for colored bmg but i also remember a separate article about how zirconium with hafnium was supposed to reduce the cost of pure zirconium for lqmt but cant find that info :( yes have seen the new twits is encouraging to see different investors and their positive impression of lqmt. https://investorshub.advfn.com/boards/read_msg.aspx?message_id=160329980
The following disclosure relates generally to the highly controlled growth and stabilization of interference layers of metal oxides on the surfaces of BMG containing parts. Embodiments herein allow for the preparation of BMG parts that exhibit consistent and uniformly thick interference layers, and therefore exhibit consistent and uniform surface colors. Consistent and uniformly thick interference layers, in accordance with the present disclosure, can be developed on BMG parts, where the BMG is based on or includes a minimal amount of one or more of any metal that forms an oxide below the crystallization temperature of the BMG. Illustrative metals that fit this description include: zirconium, titanium, palladium, tin, copper, aluminum, beryllium, magnesium, hafnium and nickel.
