“…After the hydrolysis reaction, the peak of only Na 2 CO 3 was detected. Moreover, PDMS is converted into the crystal phase of cristobalite along with complete degradation of Na 2 CO 3 during the heat treatment of 1000 o C. However, in the case of heat treatment at 500 o C, the XRD pattern shows complex peaks of Na 2 CO 3 FT-IR spectra of various precursor materials, such as TEOS, PDMS, and mixture materials (TEOS + NaOMe and PDMS+ NaOMe) are shown in Fig. 3.…”

“…Saridikmen et al studied the ceramic mold using inorganic binders with two different compositions, ethyl silicate and ethyl silicate/aluminum tri-sec-butoxide solution [3]. However, the reaction between ceramic mold and molten metal generated during the casting as well as the high temperature of molten metal (above 1450 C) and the high shrinkage of ceramic mold has lots of limiting factors to be applied to real work environments.…”

A new inorganic binder system has been developed to prepare the mold having a high strength for the thin-walled casting. To increase the fracture strength at high temperature, a large amount of inorganic binder should be converted into glass phase and the generated glass phase has to be homogeneously coated on the surface of starting particles. In this work, two types of process were employed to investigate the coating and glassification efficiencies of inorganic precursor. In the first process (process I), the green body consisting of starting powder and organic binder was dipped in the inorganic precursor solution. In the second process (process II), the starting powder was coated by inorganic precursor, and then the organic binder was used to form the green body. The mold sample prepared using process II showed the higher strength value than that using process I, owing to the inclement effect on the glassfication efficiency by the loss of inorganic precursor in process I. The prepared real mold was perfectly produced and the casted product showed a clean surface without defects such as dross, nonmetallic inclusions, and crack. Consequently, the new inorganic binder system could be applied for preparing the mold for the thin-wall casting having high mechanical properties.

“…Recently, Saridikmen and Kuskonmaz (2005) studied the effects of the binder composition on the structural and physical properties of the zircon ceramic mold by using two different binders, namely, ethyl silicate (ES) and ethyl silicate mixed with aluminum tri-sec-butoxide (ES/ATB). It was found that the ES/ATB binder was very effective to produce a ceramic mold with homogeneously distributed pores that helped to remove gases evolved during casting.…”

“…In conventional casting, the casting sand used in metal casting must have adequately high product specifications like have form ability, good permeability and is easy to produce. The casting sand production process was made simpler with short production time, it was done by only mixing sand and organic binder in molding cast made of wood [Meng Y and Thomaas, 2003;Simsir M. et al, 2009;Saridikmen H and Kuskonmaz N, 2005;Jiang J and Lin X, 2007]. Sand used for metal casting belongs to quartz sand category which is abundant in Lampung, Indonesia.…”

In Indonesia especially sumatra island, the demands for casting sand was mainly fulfilled using sand brought from ceper, central Java although with a very expensive transportation cost. For the Sumatran region, the province of Lampung is rich in quartz sand that has the potential to act as substitute to the Java originated sand. This experiment aims to characterize sand from sub district Tanjung Bintang and sub district Maringgai of Lampung province as reference for its use as casting sand. In this experiment, two kinds of sand sample extracted from Lampung province were characterized using X-RF and X-RD. Casting sand from Ceper of Middle Java province was analyzed as comparison. The results showed that although the water and clay contents of Ceper sand were higher than that of Lampung sand, the Lampung sand itself had finer particle size and morphology which were shown by higher Grain Finenesss Numbers (GFNs) than Ceper casting sand, at 48.49 for Tanjung Bintang sand and 47.61 for Maringgai sand as opposed to Ceper's 31.31. With higher GFNs value, chance of surface defect can be minimalize. Elemental analyses showed that Lampung sand contained more Al2O3 and MgO than its Java counterpart. For Tanjung Bintang sand have Al2O3 content at 13.87% and 18.76% for Maringgai sand respectively. For Ceper sand only have 4.54% for Al2O3 and for MgO, only Maringgai sand which contain it at 1.39%. These elements contribute to the improvement of the ability of produced casting sand to resist higher temperature and reducing the need for binder material.
