Barite (barium sulfate, BaSO4) occurs naturally in a variety of geological settings and is formed through several different processes. Its occurrence and formation can be understood in the context of these geological settings: 1. Sedimentary Deposits: 1. Bedded or Stratiform Deposits: Barite often forms as bedded or strati…

The whiteness meter is mainly used for measuring the whiteness of non-color objects or powder with smooth surface, and can accurately obtain the whiteness value consistent with visual sensitivity. For the object treated with fluorescent brightening agent, the whiteness value after fluorescence brightening can be quantitatively reflected.

The normal method of determining specific gravity is to weigh the specimen dry (DW), then to suspend the specimen in water on a string, and to measure the weight pulling on the string (WW) (specimen weight suspended in water). Then you subtract WW from DW, and divide the difference into DW. Example for a Specimen of lead: Dry weight (DW): 705 …

Whiteness Index ASTM E313-00.
