Holmium Oxide Purified 99.9%

Holmium oxide is faint yellow or yellow powder, which is isometric system scandium oxide type structure. It is rare earth oxide, which is insoluble in water, but not soluble in acid. Ho2O3 is insoluble in water, but soluble in acid, which is stable at room temperature and pressure.

Holmium Oxide

CAS No.:12055-62-8 EINECS No.:235-015-3 Molecular Formula:Ho2O3 Molecular Weight:377.86
Density:8.16 Melting Point:2415℃ Boiling Point:3900℃  

Applications

Holmium(III) oxide mainly applies to make new light source Dysprosium Holmium lamp. It is also additive for yttrium iron or yttrium aluminum garnet and raw material for holmium metal.

Holmium trioxide acts as magnetic material and new electric light source.

Potassium Hydrogen Phthalate

Potassium hydrogen phthalate is an acidic salt compound. It is the monopotassium salt of phthalic acid. The hydrogen is slightly acidic, and it is often used as a primary standard for acid-base titrations because it is solid and air-stable, making it easy to weigh accurately. It is not hygroscopic. It is also used as a primary standard for calibrating pH meters because, besides the properties just mentioned, its pH in solution is very stable. It can be used as a buffering agent but should not be used as a buffer for decarboxylation reactions, as these will degrade the KHP and mop up the conjugation groups. It is also a useful standard for total organic carbon (TOC) testing. Most TOC analyzers are based on the oxidation of organics to carbon dioxide and water, with subsequent quantitation of the carbon dioxide.

Terbium Metal Purified 99.9%

Terbium metal is silver gray metal, which is a kind of rare earth metal. There are two production method, distillation and reduction. Distilled terbium is dendritic with metal luster. Reduced terbium is dark gray without metal luster. Distillation method get higher purity than reduction method. It tend to corrode by air when heating, but extremely slow at room temperature.  Its main compounds include terbium trioxideterbium dioxideterbium fluorideterbium chloride and other terbium(IV) salts. Terbium can process into foil, sheet, wire, rod, powder and sputtering target. Tb ingot is of REM 99.99% by reduction method and distillation method. The distilled terbium piece is dendritic with higher purity than reduced Tb. Tb powder is of REM 99.9% and particle size -100mesh and -200mesh.

Terbium Metal

Purity: Tb/REM 99.99% 4N

CAS No.: 7440-27-9 EINECS No.: 231-137-6 Molecular Formula: Tb Molecular Weight: 158.925
Melting Point:1356℃ Boiling Point:3230℃ Density:8.27  

Applications

Distilled terbium metal apply to make high-temperature fuel cell and laser material. Calcium fluoride, calcium tungstate, strontium molybdate doped with terbium can apply to make solid state device.

Terbium magneto-optic material has bulk production, which is a kind of magneto-optic storage material. Magneto-optic disc of Tb-Fe non-crystal film can be as computer memory element, which increase storage by 10-15times.

Faraday rotatory glass containing terbium is key material in processing rotator, isolator and circulator that widely used in laser technology. Especially TerFenol. Terfenol is new material that found in 70s. Half of the alloy are terbium and dysprosium. Sometime adding holmium. The balance is iron. Tb-Dy-Ir mainly apply to sonar initially, but now it gets more and more applications as fuel injection system, liquid valve control, wing adjuster, special loudspeaker and so on.

Terbium metal can apply to do nondestructive inspection for welding spot of ships and pipeline.
