Leucite-Na-feldspar incompatibility: an experimental study
Phase relations at atmospheric pressure in the pseudobinary join KA1Si206 (Lc)NaA1Si3Os(Ab) and in the pseudoternary join Lc-Ab-CaA12Si2Os(An) indicate that leucite is incompatible with Na-feldspar. In the former join leucite can exist with an alkali feldspar of maximum albite content Ab54. In the Lc-Ab--An join, leucite only coexists with ternary feldspars with high An contents (approximately ...

It is in this connection that it becomes very difficult at times for the agricultural scientist and practical agriculturist to meet on common ground, for very often a popular version of scientific reasoning may appear ambiguous, and in this case it would appear better to sacrifice the facile version (since the layman can always get an interpreter to explain if he is sufficiently interested) tha...
متن کاملEffect of leucite crystals on the strength of glassy porcelain.
Porcelains with leucite crystals dispersed into various glass matrices were prepared for investigating the effects of the leucite crystals on the mechanical strength of glassy porcelain. The strength of glassy porcelains containing leucite crystals was affected by the differences of thermal expansion coefficients, compositions and deformation temperatures of the glass matrices. In the case of a...
متن کاملEffect of cooling condition on leucite crystals in dental porcelains.
X-ray diffractometry (XRD) was used to analyze the crystal phases of three commercial dentin and incisal porcelains prepared by normal cooling, quenching in water, and controlled slow annealing after normal firing. There were no remarkable differences in the contents of either tetragonal and cubic leucite in the fired porcelain discs prepared under the three cooling conditions. Furthermore, the...
