TL;DR: In this article, the formation of electroless Ni-B deposits and evaluation of their characteristic properties were studied. And the corrosion resistance of Ni-b deposits, in 3.5% sodium chloride solution, both in as-plated and heat-treated (450°C/1 h) conditions, was also evaluated by potentiostatic polarization and electrochemical impedance studies.

TL;DR: In this paper, a one-pot approach for the synthesis of aryl substituted quinazolin-4(3H)-ones and 2,3-dihydro-4 (1H)-quinazolinones has been reported.
Abstract: A novel one-pot approach for the synthesis of aryl substituted quinazolin-4(3H)-ones and 2,3-dihydro-4(1H)-quinazolinones has been reported based on the reductive desulfurization of 3-aryl-2-thioxo-4(3H)-quinazolinones with nickel boride in dry methanol at ambient temperature.

TL;DR: In this article, the characteristic features of synthesis of iron, cobalt, and nickel borides by boron carbide reduction of oxides were studied, and it was shown that the reaction of B2O3 and C with iron triad metal oxides occurs through a stages involving formation of the metals, lower boride phases, carbides and borates of the corresponding metals.
Abstract: We have studied the characteristic features of synthesis of iron, cobalt, and nickel borides by boron carbide reduction of oxides. We have shown that the reaction of boron carbide with iron triad metal oxides occurs through a stages involving formation of the metals, lower boride phases, carbides and borates of the corresponding metals. A characteristic feature of such a reaction is the higher reactivity of boron carbide compared with carbon in the initial stages, leading to the appearance of B2O3 and C which react at higher temperatures to form boron carbide. The method of boron carbide reduction of oxides allows us to obtain rather pure higher borides of iron, cobalt, and nickel.

19 May 2004TL;DR: In this paper, a conductive paste for a terminal electrode which suppresses oxidation of the Ni surface of an internal conductor and therefore brings about excellent joining with Ni even when baking is performed in the atmosphere is presented.
Abstract: Provided is a Ag-based conductive paste for a terminal electrode which suppresses oxidation of the Ni surface of an internal conductor and therefore brings about excellent joining with Ni even when baking is performed in the atmosphere in the case where Ni is used as the internal conductor of a laminated ceramic electronic component. The conductive paste includes at least one of an Ag powder and an Ag alloy powder, a nickel boride powder, an inorganic binder and an organic vehicle, wherein the quantity of the nickel boride powder is within the range of about 5% by weight or more, but less than about 60% by weight of the total paste.
