Ceramic specific gravity.

A ceramic slurry with a specific gravity of 1 8 is thus 1 8 times heavier than water. Compared to metals ceramics tend to have less than half of the density. Specific gravity sg coefficient of linear expansion α m m k maximum safe operating temperature o c thermal conductivity k 10 3 cal cm sec o c tensile strength σ. Specific gravity is simply a tool for you to adjust your slip to meet the needs of.

In general a specific gravity of 1 80 to 1 85 provides good balance of fluidity and strength for most casting purposes. Your order may experience shipping delays. Porcelain is a ceramic material made by heating selected and refined materials often including clay in the form of kaolinite to high temperatures. This tells us how dense the particle count is and therefore how thickly the glaze will apply.

Custom toll processing. Different clay bodies have different optimal specific gravities that are determined by good old fashioned trial and error. Specific gravity table typical for metals minerals and ceramics from reade. I ve used it as low as 1 74 for volumetric casting and as high as 1 90 for casting flat slabs.

The best way to measure specific gravity is to weigh a container and record its weight then weigh the container full of water and full of the liquid of unknown specific gravity. Contact us with questions. This chart displays specific gravity of materials which is the density of a material relative to the density of water. This number can vary though depending on exactly what is being cast.
