Abstract:
Raw material is one of the main purposes in the industry. Among the main characteristics of this material is the earthy, fine granulometry and molding function due to the plastic consistency that requires the presence of water. In the case of ceramic coating, these can be classified according to process characteristics, technological properties and applications. The corrosion of the support is a factor of great technological importance and classifies the coatings in products of red color and products of white color. However, this work has the objective of studying the technological properties of a white clay, from the city of Vera Cruz / RN, located in the micro-region of the potential agribusiness, with the objective of obtaining the technical information and indicating its economic viability. For this, the specimens were prepared by uniaxial pressure, using a hydraulic pressure with a pressure of 21 MPa. As samples were sintered in a greenhouse oven at temperatures of 900 ° C, 1000 ° C and 1100 ° C, with a heating rate of 10 ° C / min and a 60 minute isotherm. The technical variables were analyzed using linear retraction (RL%), apparent appearance mass (MEA), water absorption (AA%), fire loss (PF%) and apparent porosity (PA%). The absorption chemistry was made by X-ray fluorescence (FRX). This study is not used the knowledge of a components in the main content of mineral components and to be used to compose ceramic rocks, especially by its clear colouration, however the values of AA used industrial, especially in the coatings industry.
