Effects of potassium-silicate, sands and carbonates concentrations on metakaolin-based geopolymers for high-temperature applications

Potassium-based geopolymers have been observed to have great thermal stability, mainly due to the crystallization of kalsilite and/or leucite at high temperature as stated by V.F.F. Sakkas et al. Successfully produced a geopolymer based on potassium silicate, and with excellent passive fire-resistant properties and low thermal conductivity. After being exposed to thermal loading with a peak temperature of 1380 °C, the K-based geopolymer specimens showed no damage or visible deformations. X-ray investigation showed the presence of leucite in these samples.Materials have to have certain properties to be called fire-resistant, such as thermal stability and mechanical resistance once exposed to high temperatures, as well as chemical stability and resistance to heat decomposition. Ceramic materials are naturally able to bear heat. Geopolymers are ceramic materials generally obtained through polycondensation reactions between an aluminosilicate source, such as either kaolinitic or metakaolin clays, and an alkaline solution that contains an alkaline-earth silicate, generally potassium or sodium. The properties of geopolymers are similar to those of common ceramics, such as chemical and thermal stability and mechanical resistance. Moreover, their formulations can be manipulated to develop characteristics and properties that are useful for different applications. Different fillers can be added to geopolymer formulations to produce inexpensive ceramics with fire-resistant properties The USDA approves potassium silicate as a fertilizer for conventional agriculture. It is used on various crops, including rice, wheat, barley, sugar cane, melons, grapes and ornamentals. Potassium silicate is also used to manage certain fungal diseases on high-value crops. Silicon and potassium are found in nature, but the potassium silicate compound must be manufactured. This doesn't necessarily mean that potassium silicate is inorganic. The compound's function is to introduce more silicon into the environment after being depleted by agriculture. Silicates are extremely important in the cement, ceramic, and glass industries. Quartz is another example of silicate with an better capability to give a high rhythmic frequency vibration. The main source of the potassium mineral is weathering of the potassium silicate rocks and potash containing fertilizer. Sedimentary rocks and chloride salts are the main contributors to the chloride ions in water bodies. Potassium silicate is the name of a family of inorganic compounds.
