Platin pota kapağından sonra erimiş lityum tetraborattan yapılmıştır, using new hybrid oxidant preoxidation process of ferrosilicon alloy ferrosilicon alloy melting sample preparation is implemented. Make glass fuse piece even perfect, completely eliminates the 1 sample to test the particle size effect and the effect of the mineral, precision and accuracy results show that this law is stable and reliable, greatly improved the accuracy of the XRF analysis and stability.
