Relation between the phase composition and durability of ceramic brick older than 600 yr at the Ipat’evskii monastery
Source abstract
Abstract
Research has shown that the brick in the Ipat’evskii monastery was made using clay with high content of quartz SiO2 = 65 – 72%, calcium oxide CaO = 10 – 15% and Fe2O3 = 8 – 12%. Owing to the crystallization of mullite in the samples studied the bricks have high durability. Wollastonite, which was formed due to the elevated CaO content in the clay, creates a dense framework that impedes any change in the previous volume, i.e., it noticeably decreases stress and shrinkage in the ceramic samples.
