Distribution of chemical products
Nonferrous metal salts and oxides

Chemical products based on nickel:

atomic number: 28 | atomic weight: 58,71

Nickel is naturally found in the earth's crust in concentrations of 0.0042% and generally not in the free state but associated to numerous other metals. Nickel has a shiny white appearance and is usually mixed with other metals to produce alloys; while Nickel compounds can be used in many different applications: in the petroleum and chemical industry, in galvanic technology, in electronic engineering for preparing dry-cell batteries and in chemical laboratories. Todini has been distributing Nickel salts and oxides as well as Nickel metal for over 10 years and has become an important distributor at a domestic and international level.

nickel acetate

Nickel acetate comes in the form of a green powder and has the typical odour of acetic acid. Nickel acetate is soluble in water but not soluble in alcohol; it is mainly used as a mordant in dry cleaner's or as a catalyst in some catalytic hydrogenation reactions.

nickel carbonate paste

information not available

nickel carbonate powder

Nickel carbonate occurs as green crystals; it is insoluble in water but somewhat soluble in acids. Nickel carbonate is reduced with hydrogen at a T above 300° to obtain split nickel that is widely used in catalysis.

nickel chloride

Nickel anhydrous chloride boils at 600° and on contact with the air absorbs water and forms stable hydrated derivatives; the hexahydrate derivative has the appearance of a green crystalline powder. Nickel chloride is soluble in water, while not so soluble in alcohol and organic solvents; it is an important element for galvanic baths and in the form of anhydrous, nickel chloride is used in anti-gas masks as an ammonia absorbent. It is interesting to note that the compound in question and, more generally, all inorganic nickel salts may cause irritation by prolonged contract with the skin.

nickel fluoride

Nickel fluoride has a green crystalline aspect. Nickel fluoride is mainly used for sealing processes of anodized aluminium.

nickel hydroxide

Nickel hydroxide is a green powder that is insoluble in water but soluble in diluted acids. Nickel hydroxide is mainly used to produce other nickel salts.

nickel metal cathod electrolytic

Nickel metal is mainly used in the process called electrolytic nickel plating. Electrolytic nickel plating involves placing the object to nickel functioning as a cathode in an electrolytic bath. Some metal bars to be deposited are also placed in this bath, which are connected to the anode. Once supplied with voltage, the positive ions of the nickel to deposit migrate towards the negative pole where they are deposited forming a metallic layer.

nickel metal cathods (1 x 1)

Nickel metal is mainly used in the process called electrolytic nickel plating. Electrolytic nickel plating involves placing the object to nickel functioning as a cathode in an electrolytic bath. Some metal bars to be deposited are also placed in this bath, which are connected to the anode. Once supplied with voltage, the positive ions of the nickel to deposit migrate towards the negative pole where they are deposited forming a metallic layer.

nickel metal cathods (2 x 2)

Nickel metal is mainly used in the process called electrolytic nickel plating. Electrolytic nickel plating involves placing the object to nickel functioning as a cathode in an electrolytic bath. Some metal bars to be deposited are also placed in this bath, which are connected to the anode. Once supplied with voltage, the positive ions of the nickel to deposit migrate towards the negative pole where they are deposited forming a metallic layer.

nickel metal cathods (4 x 4)

Nickel metal is mainly used in the process called electrolytic nickel plating. Electrolytic nickel plating involves placing the object to nickel functioning as a cathode in an electrolytic bath. Some metal bars to be deposited are also placed in this bath, which are connected to the anode. Once supplied with voltage, the positive ions of the nickel to deposit migrate towards the negative pole where they are deposited forming a metallic layer.

nickel nitrate crystal

Nickel nitrate is a green crystal; it is soluble in a mixture of alcohol and water. The concentrated solution of nickel nitrate is used for the preparation of nickel catalysts used in the hydrogenation of organic derivatives. Nickel nitrate containers must be well sealed and stored in cool places away from oxidisable substances, since nickel nitrate is particularly explosive.

nickel oxide black

Nickel oxide black is a grey-black powder practically insoluble in water and also not very soluble in acids when cold; instead, when hot, it becomes soluble in HCI or in H2SO4. Nickel oxide is also known as black nickelic oxide and is widely used in the production of Edison accumulators for the preparation of electrodes.

nickel oxide green

Nickel oxide green is a grey-green powder; it is not soluble in water, but soluble in acid concentrates. The nickel is mainly used for the preparation of oxidation and reduction catalysts.

nickel powder (99,95%)

Nickel is not found naturally in the free state but is associated to numerous other metals; it is a shiny white metal and is very malleable. Nickel is hard to dissolve in sulphuric acid while it easily dissolves in nitric acid. In its powder form, known as Raney nickel, it is used as a catalyst for many chemical reagents.

nickel sulphammate crystals

information not available

nickel sulphammate solution

Nickel sulphamate solution belongs to the category of acid baths for electroplating nickel. The acid bath is normally made up of a nickel salt, in this case the nickel sulphamate, which supplies the amount of nickel to deposit on the metal; by a compound like nickel chloride that favors the attack of the anodes and by a final compound that acts as a buffer, or opposes the PH changes keeping it as unvaried as possible.

nickel sulphate

Nickel sulphate is a blue or emerald green crystal and is very soluble in water and ethyl alcohol; nickel sulphate is mainly used in nickel-plating and in the chemical industry to produce catalysts for hydrogenation of greases.

nickel sulphate (u.m.)

Nickel sulphate is a blue or emerald green crystal and is very soluble in water and ethyl alcohol; nickel sulphate is mainly used in nickel-plating and in the chemical industry to produce catalysts for the hydrogenation of greases.
