Ceramic Properties of Pugu Kaolin Clays. Part 2: Effect of Phase Composition on Flexural Strength

Whiteware compositions prepared using Pugu kaolin and industrial grade quartz and feldspar were studied with respect to varying sintering temperatures. The strength developed was correlated to mullite (3Al2O3.2SiO2) content and the microstructure. It was observed that within the vitrification temperature range, the strength mainly depended on the mullite content and the bulk density. Above the ...

Mineralogy, physico-chemical properties and industrial testing of ArazGoney kaolin deposit for ceramic and tile industry

Arazgoni Kaolin deposit is located in East Azarbaijan Province, about 18 km south of Qara Aghaj, the center of Charoymaq city. The area under investigation, in the geological zoning of Iran, is a part of the Urmia-Dokhtar volcanic-plutonic belt. Most of the study area is composed of volcanic rocks with Oligo-Miocene dacite-andesitic composition which have been strongly altered by hydrothermal a...

Copulae and Their Uses

This short survey of copulas presents their properties, tries to stress their relevance for statistics and their connection with Markov processes and conditional expectations. 1 What is a copula? Copul were introduced by Sklar(1959). The reader is referred to Schweizer and Sklar (1983), Schweizer (1991), Sklar (1973), Sklar (1996), Nelsen (1999). A copula is a function C : [0; 1] ]0; 1[! ]0; 1[...

Nuclei and their uses

⊇ Basic ⊇ Congruence ⊇ Division of sets of intervals, those sets closed under taking (a) similar intervals, (b) sub-intervals, (c) abutting intervals, (d) suprema, respectively. We let B(Λ) and D(Λ) be the family of all basic sets and division sets, respectively. Abstract and basic sets are not particularly important, but the do help with the organization. However, observe that the family B(Λ) ...
