Chemsize assures that customers will always receive the highest quality material.
FUSED SILICA FOR INVESTMENT CASTING / REFRACTORY APPLICATIONS
Chemsize produces several grades of coarse fused silica grains (stuccos) and powders (flours) for the investment casting and refractory industries. Due to fused silica’s low thermal conductivity and excellent thermal shock resistance, it is widely used in both industries.
Chemsize makes several standard grain size distributions for both applications.
These are produced by the blending of several tightly controlled fractions.
Dust removal is also given high priority for fluid bed/rainfall sander applications.
Chemsize is capable of producing powders with several different particle size distributions, by utilizing several ball mills on site. This allows the flexibility to
produce material with a broad range of particle size distributions. Particle sizing is controlled using the most up-to-date particle size analyzers.
Chemsize quality control/assurance laboratory has all of the state-of-the-art equipment necessary for testing fused silica grains and powders.
Routinely, the laboratory is capable of performing the following tests: Test sieve analysis, pH, magnetics, atomic absorption spectroscopy, Microtrac p.s.d, B.E.T.
surface area and many others.
