LOI (100-1000C) - LOI
This test procedure was employed in the Foresight Ceramic Database and now is available for those having an account at Insight-Live.com.
Accumulating test data using the variables defined in these procedures enables us to create tools that enable you to compare the physical properties of materials and recipes.
The weight lost by a ceramic compound during firing. The loss is due to water and organic materials that turn to gases. It is assumed the sample has been boil dried. Some labs also do 25-100C LOI.
For a detailed test procedure, see the LDW test.
