Abstract: The invention relates to a process for forming a cobalt-iron alloy film. In particular, the process is performed under ultrasonic vibrations to form the cobalt-iron alloy film. The cobalt-iron alloy film consists of about 75-95 wt. % of cobalt, 4.5-20 wt. % of iron and 0.5-5 wt. % of phosphorus and also has peaks at about 43.2, 45.1, 50.4, 65.5, 74.1 and 83.2 2-theta degree (2?) in the X-ray diffraction pattern.

Abstract: The invention discloses a soldering structure and process of making the same. The soldering structure comprises: a solder, a Sn—Co—Fe intermetallic compound having a thickness less than 10 ?m and a diffusion barrier layer. The process of making the soldering structure is to react the solder containing Sn with an alloy consisting of 85˜95 wt % of Co and 5˜15 wt % of Fe at the temperature between 250 and 300° C.

Abstract: The present disclosure provides a novel method to fabricate the basic nickel carbonate particulates. The nickel content in the basic nickel carbonate particulates fabricated by this invention (51-53 mass %) is higher than the present commercialized products (44-46 mass %). Basic nickel carbonate is an important intermediate to prepare NiO and pure Ni particles, and NiO and pure Ni particles are important materials in electronic industrial. Therefore, basic nickel carbonate has its potential market.

Abstract: The invention discloses a novel method to prepare the Ni(Sn, Sb)3 skutterudite compound. Skutterudite compounds are thermoelectric materials, which can transform heat into electric energy. Besides, the Ni(Sn, Sb)3 compound is also an anode material of Li ion battery. The solid state diffusion method is used to prepare the Ni(Sn1-x, Sbx)3 compound. Compared to traditional physical or chemical processes, the method disclosed in the invention is simpler and operates at a lower temperature. By the method according to the invention, the composition of the Ni(Sn, Sb)3 compound can be adjusted to fulfill variety requirements for different applications. It is noteworthy that the invention can prepare ternary compounds. In comparison with the frequently used binary compounds such as Ni3Sn4 or Cu6Sn5, the invention can produce materials with better performance.
