Abstract:
Ceramic slurries for investment casting with the potential to replace the use of zirconium silicate have been investigated. Alumina, aluminoslicates, mullite, zirconia-mullite and zircon refractory materials were characterised and paired with colloidal silica to evaluate their slurry properties. It was found that the particle size distribution of the filler affected the viscosity of the slurries under a shear rate of drainage. A larger proportion of fines in the filler were shown to form slurries with a longer draining time. This was found to impact the shell thermo-mechanical properties by in

Abstract:
The development of a disintegrating core-body for use in an art bronze foundry, which employs the ceramic shell investment process, begins with an investigation of four principal materials that will constitute the core formula. The specifications for the disintegration of the designed core-body formula fall within the parameters that are normally set and used in the ceramic shell art bronze casting process. The raison d’ être for the disintegrating formula is based on the premise that cement breaks down (spalling) after being subjected to heat above a certain temperature. It was shown that pur

Abstract:
The purpose of this thesis is to assess the current state of production of ceramic shells in MESIT Foundry, a.s. and optimize it. The shells are evaluated in terms of their bending strength, gas permeability and microstructure. Subsequently, castings produced using the shells are evaluated with regard to number of non-conforming products and presence of defects. The final part seeks to compare different shells and outlines a possible new approach to the development of ceramic shells.

In addition, fused silica can instead of zircon within primary slurry and stucco due to a low density, low thermal expansion coefficient, low specific heat and other characteristics, and prices of the zircon flours and zircon stucco soar. Therefore, the effects on the slurry and ceramic shell mold properties after fused silica instead of zircon have also been studied. There were three variable combinations within

An investment casting mould consists of individual layers of fine zircon particles and granular mullite particles by using silica gel as binder to form a shell mould. However, the whole process was too complicated and setting times required several days normally. In addition, the waste ceramic shell mould needed further disposal. In this study, outer layers of casting mould were replaced by geopolymer, which was fabricated by mixing waste ceramic shell mould, metakaolin, and the ground

With the same sintering condition, the bending strength of the ceramic shell increases with the silica content. The highest bending strength of the shell mold occurs at the silica content of 22.5% as increasing the silica content, the bending strength decreases again due to the formation of large quantity of holes after sintering. With the same silica content, the bending s

The benefits of EPD process are simple facilities, low cost, high deposition rate, and good surface finish. Nowadays, EPD is used widely for the fabrication of ceramic film. In this study, EPD process was used to fabricate ZrO2 primary coat on the conductive plastic, then the primary coat was set for drying after EPD process. The conventional shell building

The results showed: for the properties of backup slurry, the decline of pH was relaxed when the amount of kaolin additives were 3 wt% and 5 wt%; when the adding amount was up to 10 wt%, the decrease of pH was more obviousl

According to the selected refractory, its effects on the ceramic shell molds will be different, too. Fused silica has the properties of low density, low thermal expansion, and low specific heat. Besides, when the fused silica containing ceramic shell mold is heated and sintered up to 1100℃, and then cooled to 270℃, the high temperature cristobalite is transformed into low temperature cristobalite, and leads to the volume change. This phenomenon causes the decrease of
