Sierralite Talc


Formula: 2Mg0.2Si02.Al203.H20
Alternate Names: Sierralite 252HS

Oxide Weight103.35
Formula Weight118.25
If this formula is not unified correctly please contact us.
DENS - Density (Specific Gravity) 2.64
GEBR - GE Brightness 92
pHPW - pH for dry powder 8.5
P200 - % Passing 200 Mesh Wet 99.8%

This is 95% chlorite, less than 5% talc, less than 1% quartz.

Here is a grade comparison between the various Montana Talc products made by Imerys Talc:

Yellowstone: Microcrystalline 200 mesh. Excellent for steatite insulators and as a flux for high alumina ceramics.
Steawhite 2: 200 mesh steatite talc that fires off-white. Low alkali and low iron content. Excellent for electrical porcelain / glazes and color sensitive steatite applications.
Luzenac 2C: Unique talc-chlorite mineral that contains relatively high amounts of aluminum in the crystal lattice. Used in cordierite applications, sanitaryware flux, white-body floor tile and vitreous china.
Sierralite 252HS:Chlorite with high alumina content and low iron oxide content. Used in ceramics and refractory materials requiring low thermal expansion and good thermal shock resistance.
