Halogen and Sulfur Free Metal Organic Metal Compound (Resinate)

About metal resinate (Organic metal compound)

Metal resinate is also called organic metal compound (including solutions). It is used for a minor component as a metal additive or a material of metal films, alloy films (Au,Pt) and oxide films (Ru, Pd).
We have widely looked on and manufactured the resinate of a platinum group which is especially effective as a catalyst and electrode.

 

Features

1

- Halogen and Sulfur Free

It generates no corrosive gases on decomposition,
so we can prevent alternation of other materials,
deterioration of the equipments and
environmental pollution.
2

- Useful as a minor component Additive or for very thin film coating (for Surface activator etc.)

It can be homogenously mixed at molecular
level with various pastes, and be useful to
coat very thin films of nano meter order,
applicable to surface activator.
3

- Wide range of firing temperature conditions

Low temperature sintering is possible due to the
formation of metal with very small size on the
thermal decomposition, and a high temperature
process is also applicable with the addition of
some sintering retardant.

We are also offering concentrated aqueous solutions of dielectric materials such as titanium oxide, used for manufacturing powders and films of TiO2, BaTiO3, PbTiO3, (Ba,Pb)TiO3. Additionally Ba(Ti,Zr)O3, Pb(Ti,Zr)O3, (BaPb)(Ti,Zr)O3 etc. also can be formed by concomitant use of commercially available zirconium oxide aqueous solution.

New Product: Iridium Resinate

Our corporation has prepared platinum group resinates by using non-halogen starting materials, offering their solutions and metal pastes based on them. Iridium resinate virtually free from Chlorine (containing less than 0.1% of residual chlorine to Iridium atom) has been developed recently. This resinate is easy to form into the paste because it is well soluble in various organic solvents and compatible with various polymers. The resinate is also usable as an additive of iridium metal. Iridium metal is expected to become a good additive for improving heat resistance of metal films due to the characteristics of small solubility to metallic Gold and Silver.
Iridium Acetate, which is soluble in water and stable in the air, is also available
