Lithiummetaborate,octahydrat - Determination of tantalum and niobium in geological samples by inductively coupled plasma mass spectrometry with lithium metaborate fusion
from VIP Journal Professional Edition
Author:
Abstract:
The sample was decomposed by lithium metaborate melting method, and the sample was dissolved by ultrasonic cleaner. The tantalum and niobium in rock were directly determined by inductively coupled plasma mass spectrometry in 5% aqua regia medium. The detection limits of this method were 0.11 μg · g-1 for Nb and 0.045 μg · g-1 for Ta. The recovery rate of the method was between 95.6% and 104.4%, and the method precision (RSD%) was between 0.79% and 6.59%. The method has the characteristics of low detection limit, simple operation, high precision, high accuracy and fast analysis, and is suitable for the determination of tantalum and niobium in geological samples.

Lithiummetaborate,octahydrat - Lithium metaborate-doped lithium hydride hydrogen storage composite material and preparation method thereof
Application (patent) number:
CN201510385371.0
applicant (patent):
Yanshan University
inventor:
Han Shumin , Ma Yufei , Liu Ting , Liu Yang , Guo Liangliang
Abstract:
A lithium metaborate-doped lithium hydride hydrogen storage composite material consisting of LiBO2 and LiH in a molar ratio of LiBO2:LiH = 0.5 to 2:1. The preparation method of the lithium metaborate-doped lithium hydride hydrogen storage composite material is mainly to uniformly mix LiH and LiBO2 according to the above molar ratio under the protection of argon, and then place them in a ball grinding tank for ball milling treatment, the ball milling time is 1~5h, the ball-to-material ratio is 10~40:1, the rotation speed is 200 ~ 500r/min, the ball milling method is forward/reverse intermittent ball milling, the ball milling is 15min, after the end of ball milling, it was naturally cooled to room temperature, and the prepared composite material was taken out under the protection of argon and sealed and packaged to obtain lithium metaborate-doped lithium hydride hydrogen storage composite material. The invention has the advantages of simple preparation method, easy availability of raw materials, low cost, low hydrogen release temperature and fast hydrogen release rate, and is beneficial to industrial mass production.
