The majority of feldspars found in geopolymers are triclinic and have smaller cations (Na +, K +, Ca 2+) in the structure. Feldspars are known to undergo various order–disorder or displacive phase transitions [131]. The temperature of crystallization depends on the alkali content in the system and the composition of solid precursors [35 ...
What is Feldspar? Feldspar is the name of a large group of rock-forming silicate minerals that make up over 50% of Earth's crust.
