| Application: | Lithium tetraborate may be used as an analytical reagent for the analysis of major and trace elements in coal fly ashes and environmental materials using inductively coupled plasma atomic emission spectrometry (ICP-AES). It may also be used as an alkali fusion reagent for the determination of silicon in zirconium oxide powder using ICP-AES. |
| General description: | Lithium tetraborate in combination with oxalic acids and lithium carbonate in the ratio (1:1:1) may be used as an effective fusing agent for siliceous samples. It is widely employed in lithium tetraborate fusion procedure, suited for a variety of soils and rocks. Lithium tetraborate also finds applications in radiation detectors and dosimeters. |
