HI:

 

Any volunteers, please, tell me the uses of these forms of silica gel listed below:

****************
The forms of amorphous silica for which there are or have been health standards are * ditomaceous earth-calcined,
* diatomaceous earth-uncalcined,
* precipitated and gel,
* fumed, and
* fused. 

fumed is the only one that has no NIOSH, MAK, OSHA, of AIHA standard and the TLV was withdrawn. 

Monona

 

Thanks,

 

Po-Yung
