What is a hexachloroiridic acid hexahydrate ?
Hexachloroiridic acid hexahydrate absorbs damp easily, can acrid in water, hydrochloric acerbic and alcohol.It can accident of clear baptize to breach down if apparent to able heat.It is acclimated in the accomplish of coated electrodes and is an important actinic reagent iridium agitator and raw materials.
Chloroplatinic acerbic arrangement of law is the platinum metal is attenuated in aqua regia. The artefact of this acknowledgment is H2PtCl6, instead of a nitrogen-containing platinum compounds ahead thought. The chloroplatinic acerbic is a red-brown solid, which can be acquired from the dehydration of the band-aid thereof. Chloroplatinic acerbic is frequently acclimated for audition the attendance of potassium ions. Potassium chloroplatinate, potassium ions can be generated with the chloroplatinic acid. The apprehension action is the acknowledgment with an balance of chloroplatinic acerbic in 85% (v / v) ethanol, and again the consistent accelerate was weighed, which abstinent potassium content. Potassium in the authentic assurance of amid 0.02 to 0.2% of the absorption of the band-aid of chloroplatinic acerbic (m / v).

What is rubidium?
Rubidium (Rb) is a actinic substance, silver-white adhering metal. Soft, light, chemically acknowledging than potassium. The aftereffect of light, simple to afford electrons. Extreme with water, breeding hydrogen and rubidium hydroxide. Easily with oxygen to anatomy oxides. The baptize acknowledging afford a lot of heat, so to accredit the hydrogen afire immediately. The authentic metal rubidium usually stored in kerosene.
Is a byproduct in the admixture action of a metal such as lithium, cesium, rubidium. These minerals absolute trace amounts of rubidium. Rubidium is the accomplish of cyberbanking accessories (photoelectric photomultiplier tube), spectrophotometer, automated control, spectrometry, blush film, blush television, radar, laser as able-bodied as glass, ceramics, cyberbanking alarm and added important raw materials; in amplitude technology, ion propulsion and thermionic advocate requires a lot of rubidium; rubidium hydride and borides can be acclimated for high-energy solid fuel; radioactive rubidium assurance of mineral age, in accession to the rubidium compounds acclimated in the pharmaceutical, lurid and paper; can aswell be acclimated as a exhaustion arrangement getter. Getter role agnate to the antibacterial agent, the abatement of balance gas may alloy the system.

The nature and use of the nickel sulfamate
The nickel sulfamate blooming crystals. Acrid in water, aqueous ammonia, ethanol, hardly acrid in acetone, aqueous band-aid is acidic, hygroscopic anon condensate in clammy air. Dry air apathetic weathering lose four molecules of water, if heated, begins to decompose if the temperature is college than 110 and the accumulation of basal salts and heating was connected to accomplish a black-brown nickel sesquioxide and blooming oxyalkylene a admixture of nickel.
The nickel sulfamate Is a acceptable plating capital salt, because of its low centralized stress, the plating acceleration is fast, solubility, non-polluting, and the plating of the all-embracing association in contempo years the accelerated development of a adept salt. Has been broadly acclimated in the electronics, automotive, aerospace, weapons, coinage, metallurgy, nickel screen, radio, blush aluminum and added industries.
Method: Synthesis: amino acerbic with nickel hydroxide produced by the acknowledgment of nickel sulfamate, was concentrated and crystallized from centrifugal separation, a nickel sulfamate finished.

What is slag?
Product name:slag
Product description:Slag is a partially brittle by-product of admixture ore to abstracted the metal atom from the exceptionable fraction. It can usually be advised to be a admixture of metal oxides and silicon dioxide. However, slags can accommodate metal sulfides (see aswell matte) and metal atoms in the basal form. While slags are about acclimated as a decay abatement apparatus in metal smelting, they can aswell serve added purposes, such as acceptable in the temperature ascendancy of the smelting; and aswell aspersing any re-oxidation of the final aqueous metal artefact afore the aqueous metal is removed from the boiler and acclimated to accomplish solid metal.
Plays the following important physical and chemical effects of slag in the smelting process: ① form a molten slag to the gangue components or impurities oxidation product with the molten metal or molten matte smooth separation; (2) removal of harmful impurities in the liquid steel sulfur, phosphorus and oxygen, absorption of non-metallic inclusions in molten steel, and protect the liquid steel from the direct absorption of hydrogen, nitrogen, oxygen; ③ enrichment useful metal oxide; ④ smelting furnace (electric arc furnace, mineral hot furnace, electroslag remelting furnace, etc.) the slag also plays the role of the heating resistor.
