Investigation Of The Effect Of Vermiculite (Yıldızeli/Sivas) Addition On The Properties Of Sanitaryware Ceramic

Sanitaryware is the generic term used to describe items which traditionally were made from pottery. i.e. toilets, washbasins, pedestals, bidet, urinals, sinks, bathtubs installed within a bathroom or washroom. products are primarily of clay, kaolin, feldspar and quartz but they may also include small quantities other raw materials. Its high gloss, stain resistant surface ideal for use in both bath-rooms kitchens. Vermiculite, mineral hydromicas group occurs naturally, becomes high-efficiency thermal insulation material when heated above 300 ℃. The expanded vermiculite can be as filler heat insulating materials due its unique properties, low bulk density, conductivity, relatively melting point, chemical inertia, durability environmental safety. In this study, effects obtained Yıldızeli/Sivas region on sanitaryware body properties investigated. study calcined vermiculite, quartz, kaolin ceramic compositions prepared by using kaolin-feldspar-quartz ternary equilibrium diagram according appropriate recipe material. accordance with purpose; bodies %0, 10 20 weight (1050 oC 1 hour) was added formed compositions. samples coded S20V1100 (S: Sanitaryware; 20V: 20% addition 1100: 1100 °C firing temperature). Mixtures homogenized Alumina ball mills (60 rpm, 24 hours) shaped uniaxial dry pressing (100 MPa). Then, pressed fired at 1050-1100 1150 hour. Microstructure (SEM), phase analysis (XRD), mechanical (hardness, 3-point bending) physical (% shrinkage, water absorption, porosity density) tests performed produced. data presented graphs tables commented. Accordingly, doped specimens successfully developed optimum parameters clearly shown. According results, it has been shown that improved increase vermiculite.
