Ceramic Specific Gravity

The specific gravity of a glaze is an extremely important number in ceramics it tells us how many particles of actual glaze material exist in a standard unit.

Ceramic specific gravity.

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. This chart displays specific gravity of materials which is the density of a material relative to the density of water. Compared to metals ceramics tend to have less than half of the density. Specific gravity is simply a tool for you to adjust your slip to meet the needs of.

Custom toll processing. Specific gravity density fine ceramics are lighter than high strength metals and weigh roughly 50 of metals having the same volume. Freight carriers are giving logistical priority to items that are necessary in the fight against covid 19. In general a specific gravity of 1 80 to 1 85 provides good balance of fluidity and strength for most casting purposes.

I ve used it as low as 1 74 for volumetric casting and as high as 1 90 for casting flat slabs. A ceramic slurry with a specific gravity of 1 8 is thus 1 8 times heavier than water. Contact us with questions. Specific gravity table typical for metals minerals and ceramics from reade.

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. Furthermore tungsten is heavier than lead and around the same weight as gold making it an unusually dense material. 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.
