Thermoluminescence study of based materials of ceramic tiles

Author(s): H.C.Mandavia, K.V.R.Murthy

Many flooring materials most of themare in natural formare used to manufacture floor tiles for household flooring purpose. The peoples demand for variety of flooring material Leeds to develop various types of ceramic tiles. In India ceramic industry is fast growing one, more then 400 units of manufacturing ceramic tiles, vitrified tiles and sanitaryware, situated aroundMorbi, Rajkot, Gujarat, India.Many natural minerals are used as the rawmaterials required for the manufacturing ceramic ware. The following minerals are used to manufacturing the ceramic tiles i.e. Quartz, Feldspar, Zircon, Talc, Grog, Alumina oxide, etc. Most of the minerals are from Indian mines of Gujarat and Rajasthan states, some of are imported fromRussian sub continent. The present paper reports the thermoluminescence characteristics of Feldspar,Alumina andQuartzminerals collected fromthe ceramic tilesmanufacturing unit,Morbi. The as receivedminerals TLwas recorded (NTL), and annealed and quenched from500oC and 9000C followed by 15Gy beta dose given from Sr-90 beta source TL was recorded and the comparative TL (Thermoluminescencs) study of above materials are presented and it represent some special characteristics of the materials. The TGA and X - rd of such materials are also given for batter understanding.
