Early Stage of Solid State Interfacial Reaction between Copper and Tin

Synthesis & Characterization of CaB4O7 Powder by Solid-State Reaction

The synthesis of calcium tetraborate was investigated in a temperature ranging from 800℃ to 900℃ using the solid-state reaction method. The synthesis was done using ammonium tetraborate tetrahydrate as the source of boron. At temperatures of 800 ℃ and 880 ℃, the mixed phases from different compounds were formed. At the optimum temperature of 840℃, the mixed phase was only composed of meta and t...

Ti2Al(O,N) formation by solid state reaction between substoichiometric TiN thin films and Al2O3(0001) substrates

Wettability of Liquid Tin on Solid Copper* By

For obtaining good joints by soldering, a wettability of liquid metal on the solid metal surface, relatlatte, relattlated o solderability, is one of the most important factors, and the wettability is accelerated by using a suitable flux and atmosphere. In atmosphere soldering the flow of molten solder will be retarded by oxide films on base metals formed by a small amount of oxygen in atmospher...

Solid-state reaction between sulfadiazine and acetylsalicylic acid.

Kinetic data for the solid-state reaction of sulfadiazine and acetylsalicylic acid are presented. A compaction method was used to observe the influence of applied pressure, particle size, and temperature on the reaction rate.

Kinetics of the Solid State Reaction between CuO

The solid state reaction of CUWO4-2 formation from CuO and WO3 was studied by the contact method in air and nitrogen. The results showed that the reaction is governed by the diffusion of the W 6 + and 0 2 _ ions and that the rate determining step is the diffusion of oxygen ions in the reaction product. This is in agreement with the defect structure of copper tungstate, an n-type semiconductor w...
