Goal of researches |
Calculation of the opened and closed porosity of solid-state samples and creation of a 3D-model of pore space. |
|
Application areas |
Geology, zoology, botany, building materials, paper manufacture, biomedical researches, material science, pharmaceutical drug development and manufacturing, composites, dental researches, electronic components, and many more. |
|
Determination of the sizes of pores and their distribution in a sample are necessary for investigation of physical and chemical conditions of receiving, application and an internal structure of substances and objects, and also at creation of various mathematical models. |
|
|
Sampling |
Samples for micro- and nano tomographic researches have to maintain temperature increase to 40°C without change of the geometrical sizes. The sizes of samples: no more than 30 x 30 x 30 mm (Skyscan 1172); no more than 2 х 2 х 5 mm (Skyscan 2011). |
|
Sample preparation |
Preparation of samples doesn't required. |
|
The method |
The method of measurement of porosity is based on mathematical data processing about an internal structure, received by X-ray microtomoraphy method. The software (CTAn) and methodical recommendations of Bruker-microCT-developer are used. |
|
Accuracy |
The sizes of the pores depend on the resolution reached at the shooting of sample and make more than three pixels on each measurement. |
|
Reagent required |
no |
|
The necessary equipment |
Microtomography scanner SkyScan 1172 or nanotomography scanner SkyScan 2011. Soft – CTAn (Bruker micro-CT). |
|
Literature |
Methodical recommendations about opened and closed porosity determination (Bruker micro-CT). |
