Uses
Different sources of media describe the Uses of 1314-36-9 differently. You can refer to the following data:
1. Yttrium Oxide, also called Yttria, high purity Yttrium Oxides are the most important materials for tri-bands Rare Earth phosphors which give the red colour in colour television & computer tubes. In optical industry, the Yttrium Oxide is used to produce Yttrium-Iron-Garnets, which are very effective microwave filters. Low purity of Yttrium Oxide are widely applied in electronic ceramics. It is widely used to make Eu:YVO4 and Eu:Y2O3 phosphors that give the red color in color TV picture tubes.
Also, it is used in gas mantles and acetylene lights. Other uses are in yttriumiron garnets for microwave filters in lasers, and as a stabilizer for high temperature in refractories.
2. Yttrium oxide is an excellent mineralizing agent for spinel formation. Yttrium oxide is used as a common starting material for both materials science as well as inorganic compounds. Provides easy application of uniform, thin, protective high temperature Yttrium Oxide coatings. Yttrium Oxide is used to produce Yttrium-Iron-Garnets, which are very effective microwave filters. Low purity of Yttrium Oxide are widely applied in electronic ceramics. Yttrium Oxide is also used to make Yttrium-Iron-Garnets, which are very effective microwave filters.
3. Yttrium oxide was used in the preparation of pervoskite type structure, YAlO3, containing chrome ions.1 The effect of yttrium oxide dopant on the phase formation and sintering characteristics was studied. It may be used in the manufacturing of neodymium Nd:YAG lasers and in components of MOS and LED transistors.
Preparation
Yttrium oxide is produced as an intermediate in recovery of yttrium from xenotime and monazite (See Yttrium, Recovery). The oxide is produced after separation of rare earth sulfates obtained from digesting the mineral with sulfuric acid on a cation exchange bed, precipitating yttrium fraction as oxalate, and igniting the oxalate at 750°C.
Yttrium oxide also may be obtained by thermal decomposition of yttrium nitrate.
Chemical Properties

Check Digit Verification of cas no
The CAS Registry Mumber 1314-36-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,1 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1314-36:
(6*1)+(5*3)+(4*1)+(3*4)+(2*3)+(1*6)=49
49 % 10 = 9
So 1314-36-9 is a valid CAS Registry Number.
