21. By reacting the resulting yttrium oxide with hydrogen fluoride, yttrium fluoride is obtained. 22. By reacting the resulting yttrium oxide with hydrogen fluoride, yttrium fluoride is obtained. 23. In this way, yttrium salts of 99.999 % purity are obtained. 24. It also contains 10, 000 times more yttrium and zirconium than the Sun. 25. His primary concern is yttrium -90, which shows promise as a cancer treatment. 26. Sometimes mineral fluorite contains admixtures of yttrium . 27. Take a look at Yttrium aluminium garnet. 28. Yttrium has been studied as a nodulizer in shock resistance and low thermal expansion properties.29. Yttrium -90 has a wide and valuable use in radiation therapy to treat cancer.30. In the treatments, yttrium -90 is attached to a protein called a monoclonal antibody.
