Chemical Analysis | Al203 Máx.0,9% -Si02 98-99% -Fe03 Máx,0,4% |
Density | 2.080kg/m3 |
Installation | Dry hand ramming or using specific vibration equipments for bottom and sidewalls. See instructions manual. |
Storage | Pallets must be stored in a dry place. Once open, it must be totally consumed or, at least, cover the remaining sacks with a plastic sheet. Maximum lifetime: 12 months. |
Packing | Paper sacs of 25 kg. |
Drying and Heating | Depending on furnace’s capacity, heat up to working temperature at a rate of 100-180ºC/h. (with Boron Oxide as a sintering agent) or at 60-120ºC/h. (with Boric Acid). Sintering should be done at 30-50ºC over the working temperature, keeping this temperatu |
