For \(\mathfrak{g} = sl(n)\) we construct a two parametric \(U_h (\mathfrak{g})\)-invariant family of algebras, \((S\mathfrak{g})_{t,h} \), that is a quantization of the function algebra \(S\mathfrak{g}\) on the coadjoint representation. Along the parameter t the family gives a quantization of the Lie bracket. This family induces a two parametric \(U_h (\mathfrak{g})\)-invariant quantization on the maximal orbits, which includes a quantization of the Kirillov-Kostant-Souriau bracket. Yet we construct a quantum de Rham complex on \(\mathfrak{g}*\).
