Abstract
The objective of this work is to study the effect of different composition of potash feldspar and soda feldspar at different firing temperatures to the properties of the porcelain tiles. The raw materials of porcelain tiles in this work were Trong clay, silica, potash feldspar and soda feldspar. Parameters studied in this work were ratio composition of soda feldspar to potash feldspar [0:40 (T1A, T7A), 5:35 (T2B, T8B), 10:30 (T3C, T9C), 20:20 (T4D, T10D), 30:10 (T5E, T11E), 40:0 (T6F, T12F)] with two different firing temperature (1150°C and 1200°C). The powder was mixed using a dry mixing method and then followed by a milling process for 8 hours to achieve homogeneous mixture. Then, the powder was pressed to the rectangular shape using 35MPa of pressure. The sample was dried overnight in the oven in order to remove the excess moisture before being fired at two different temperatures (1150°C and 1200°C) with 2 hours soaking time and 5°C/min of heating rate. Fired samples were characterized by physical properties and mechanical properties (modulus of rupture, MOR). Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD) were used to observe the microstructural analysis of fracture surfaces and phases present in the fired bodies of porcelain tiles. Composition 40% of soda feldspar (T12F) fired at temperature 1200°C has lowest water absorption (0.12%) and highest MOR (65.2 N/mm2) due to lowest porosity (0.2%) formed. The XRD phase analysis shows the formation of the mullite phase which is a significant factor for the strength of porcelain tiles. In conclusion, 40% soda feldspar provided the optimum composition that can be substituted in the porcelain tiles at firing temperature 1200°C.
