Drying agent with the capacity to absorb 27% of its weight in water within one day at 80% relative humidity. Bulk density is about 0.7 (70g/100ml). 2 to 4mm pellet size range, which equates ASTM mesh 8 to 10. Dry pellets are orange and turn dark green when near saturation. Heat applied to an open container holding silica gel - a hotplate or an oven at 110°C, will restore silica gel to its previous moisture absorbing capability. Unlimited cycles are possible.
Silica gel is produced by the reaction of sulphuric acid with sodium silicate.
Orange silica gel does not contain cobalt, which is the indicator in blue silica gel. Silica gel has very low toxicity and ingesting or inhaling small amounts of silica gel dust is not harmful.
Silica gel does not dry completely below about 105°C. The orange indicating dye may be damaged at temperatures above 125°C. Higher temperatures also cause progressive collapse of the fine adsorbend structures. ProSciTech recommends refurbishing of silica gel between 105 and 120°C for at least 2 hours, depending on depth of pellets.

Use this to make silver loaded epoxy and more. Very fine, high purity silver powder. May be used to produce electrically highly conducting paints and especially epoxy resins. Usually, the mixture is one half by volume, of powder and a quarter each of epoxy components A + B. These materials mix very easily, but conductivity does not gradually change; rather if a little less silver is used, suddenly conductivity may be completely lost.
Unlike prepared silver epoxies, the powder has an unlimited shelf life and the mixture ratio can be varied to suit. Also, fast-curing or super-strong epoxy may be used as required and silver powder is rather more economical than prepared epoxies.
Note that because of the small particle size the powder and any solutions made are a little yellowish and darker than silver. This relates to particle size and refractive index and not purity.
Product data:
- Average particle diameter 1.4-3.6(µm) (ASTM B330-82)
- Apparent (tap) density 1.6-2.6 g/cm3 (ASTM B527-81)
- Spec. surface area 0.2-0.6m2/g (Quantachrome Monosorb BET Method)
