Material: Wollastonite NYAD G (2)

GENERAL INFO IMAGE

Provenance: New York (USA)

Description: The actual value of the FPTI index of the sample is 2.12. The difference from the actual value is due to the "diameter" parameter. In fact, the wollastonite has an average diameter of 3.74 µm , which is above the upper limit set by the FPTI model (i.e. 3 µm). This means that the "diameter" parameter has a weight of 0. In this document, the FPTI index has been calculated after careful characterisation of the sample. NEW ERROR CALCULATED!
