1 Subject Content and Scope of Application
1.1 Subject ContentwwW.bzxz.Net
This standard specifies the determination of ignition loss of high purity quartz sand. 1.2 Scope of Application
This standard applies to various grades of high purity quartz sand. 2 Method Summary
SJ3228.3—B9
The adsorbed water, carbonates, organic matter and other volatile substances contained in the sample will decompose and volatilize after high temperature ignition. The amount lost by ignition is the ignition loss. 3 Analysis Steps
Accurately weigh 1g of the sample, place it in a constant platinum glass, cover it and place it in a 9501000℃ muffle furnace to ignite for 1h, transfer it to a desiccator and cool it to room temperature before weighing it. Ignite for 20min, cool and weigh it, and repeat the ignition until constant.
4 Calculation
Ignition loss (%) = m1 = m = x × 100
Wherein: m1——Platinum and sample weight before ignition. g, m2——Platinum crucible and sample weight after ignition. g
m-Sample weight. g.
