EFFECT OF PARTICAL SIZE OF THE RAW MATERIALS USED IN FLOOR TILES CERAMIC INDUSTRY ON SOME PROPERTIES WHICH EXTRACTED FROM WESTERN DESERT OF ANBAR.

Abstract

The partical size play a big role in determination of floor tiles products characteristics, So the idea of this research came to study the effect of the partical size of the raw materials (caoline , glass sand , limestone, sodium silicate ) which extracted from the Anbar western desert in Iraq ,Including various types of stones and metals and it's consider as greater field for metals in Middle East, The effect of partical size on some physical properties such as water adsorption, resistance for thermal shock ,shrinkage after pride and the mechanical properties which represent by durability,We used raw materials with partical size 53 , 65 , 77 , 85 , 110 and 140 µm and used manufacturing methods similar to that used in General company of ceramic industry in Anbar province from where mixing ratio, incineration conditions. The study showed that the partical size play a big role in determination of products characteristics, So the best size of raw materials was 77 µm give the lowest ratio of adsorption of water which is 14.5% and the resistance of thermal shock 150 thermal period , the shrinkage ratio was the least possible 0.5%, also we noticed improvement in durability which was 137 kg .m-2.
