Talc is a stone-like layered mineral.

Talc comes in its natural colors of white, pink, light green, gray, etc., and, after being crushed, becomes white or gray powder.

Magnesium silicate hydrate, chemically known as {Mg3Si4O10(OH)2}.

Talc has a specific gravity of 2.7 and a Mohs hardness of 1, making it one of the softer minerals among inorganic minerals. It is also heat-resistant and chemically stable.

Talc is found worldwide, but high-purity, industrially valuable raw stones are primarily located in China, India, and Pakistan.

The case employs the EDX9000B plus X-ray fluorescence spectrometer for non-destructive rapid testing of the content of various components in talc, achieving good accuracy and precision.
