5. How to check the garnet contamination test?

Question

Accepted Answer

To check garnet contamination, perform a visual inspection, use a magnet test, and conduct a sieve analysis.

Perform a visual inspection to identify any visible contamination on the surface.
Use a magnet test to check for magnetic contamination. If the garnet particles are attracted to the magnet, it indicates contamination.
Conduct a sieve analysis by passing the garnet through a series of sieves to determine the particle size distribution. Contamination may cause variations in particle sizes.
Compare the results of the visual inspection, magnet test, and sieve analysis with the specified acceptance criteria to determine if the garnet is contaminated.
