Development of Geopolymer Ceramic as a Potential Reinforcing Material in Solder Alloy: Short review

Abstract

Nowadays, the consumption of lead-free solder has been widely used around the world since the utilization of SnPb solder has been banned and restricted by European Union. Variety of studies have been conducted by the researchers to find an alternative to replace the usage of SnPb such as SnCu, SAC, SnAg and etc. However, the development of plain lead-free solder was declared to provide low mechanical, thermal, and electrical properties in terms of interfacial intermetallic compound and wettability towards its solder joint compare to the traditionally monolithic SnPb solder alloy. Mostly, previous studies stated that addition of some additives such as ceramic particles (Si 3 N 4, TiO 2, SiC, NiO and etc) may improves the solder joint reliability. At the same time, no major studies were done using geopolymer ceramic as reinforcing agent in plain matrix alloy. Therefore, this paper reviews the fabrication process of multiple geopolymer-based ceramic such as fly ash, kaolin, and slag as reinforcement in solder alloy. The development process includes the processing method of geopolymer ceramic and the characterization of geopolymer ceramic as reinforcing material consist of; i) chemical composition, and ii) phase identification.

Durability Study on the Red mud-based Ternary Blended Geopolymer Concrete

“…Industrial byproducts rich in silica and alumina, such as fly ash, blast furnace slag, alccofine, silica fume, and rice husk ash, can be used to make geopolymer. Geopolymers are made by dissolving rich silicate compounds in an alkaline solution, which results in a 3-D polymer link structure of silicones and aluminum silicates [9]. Geopolymer has been demonstrated to outperform regular Portland cement in terms of advanced strengths, quicker setting time, longer sustainability, higher acid and corrosion resistance, lower thermal conductivity, and shrinkage [9,10].…”

The majority of previous studies used heat curing to finish the geopolymerization technique for the FA-based geopolymer [11].…”
