Ceramic Slurry. A ceramic slurry containing a high solids loading of PZT with a certain set of rheological properties needs to be developed for the lost mold technique prior to the impregnation of polymer molds. From: Comprehensive Composite Materials, 2000. Related terms: Infiltration; Wood's Metal; Investment Casting; Sintering; Binders ...
Ceramic shell moulds in investment casting is essentially compromised of ceramic stuccos, ceramic filler and binder usually made from ceramic colloidal sol. Ceramic stuccos and filler is selected based on mould drying effectiveness, madeup slurry characteristics, mechanical strength, refractoriness.
Investment casting is a manufacturing process in which a wax pattern is coated with a refractory ceramic material. Once the ceramic coating material is dry and hardened, the wax is melted out and leaves an internal cavity the shape of the final product's geometry. Molten metal is poured into the cavity where the wax pattern was.

Investment casting requires the use of a metal die, wax, ceramic slurry, furnace, molten metal, and any machines needed for sandblasting, cutting, or grinding. The process steps include the following: Pattern creation The wax patterns are typically injection molded into a .

· · Investment casting is a technique, as shown in Fig. 2, during which a wax pattern is coated with a refractory ceramic slurry, stuccoed, and allowed to dry in a repeating layering process to form a set of ceramic molds ().The wax is subsequently melted from the mold to form a cavity and the green ceramic component is fired to yield a sintered mold with sufficient mechanical strength.
The main difference between investment casting and ceramic shell investment casting is that, in the former process, before dewaxing the wax pattern, it is immersed in a refractory aggregate. Whereas in the ceramic shell investment casting, a ceramic shell gets built around the tree assembly through repeated dipping of the pattern into slurry (refractory material such as zircon with binder).
investment casting. Sidhu et al. [19] studied the effect of slurry composition on plate weight in ceramic shell investment casting process. However, little is known about the characteristics of the primary slurry for titanium investment casting. Hence it is significant and necessary to investigate the properties of the
Investment casting involves pouring molten metal into wax patterns coated with ceramic slurry. The first part of this process is to make moulds into which wax gets injected to make wax patterns. The important part of investment casting is that the wax patterns are single use.

Fused Silica is employed in a variety of industrial appliions including foundry (investment casting slurry and stucco, and mould release agent), refractory and ceramic (crucibles, saggars, rollers, pouring cups, ceramic cores, gas fire radiants and items for steel, nonferrous metal and glass industries), and filler (electronic and adhesive).

The most common method of investment casting involves ceramic mold production. This production is characterized by the repetition of alternating layers of liquid ceramic slurry and dry refractory powder, "stucco", to form an investment– or shell– around a wax pattern.
A composition and method for forming investment casting shells includes using colloidal silica, zircon flour, and fused silica in a slurry which is applied to a pattern. After the slurry is applied to the pattern, it is allowed to partially or completely solidify. After the shell has solidified, the pattern may be melted or otherwise removed.

a very short lifetime. Lack of sufficient slurry life can make the shellmaking process more costly. Moreover, the quality of shells may become unsatisfactory even in batch processes. The purpose of this paper is to outline a methodology for the design of ceramic shell mold systems suitable for casting .

Ice patterns generated by rapid freeze prototyping or a molding process can be used to make ceramic investment molds for metal castings. Due to the use of ice, the ceramic slurries must be poured around the pattern and cured at subfreezing temperatures. Success of this process depends greatly on the mold strength after the gelation of the slurries.
Has this been done? I don't require the best stuff, I just want something that works decently. Can't use plaster since I want to cast bronze. I have not found a single god damn place or webshop that sells ceramic slurry for casting outside of US or asia and I'm not too excited to pay shipping to sweden for something that heavy.
