Abstract

A coloring solution for dental zirconia ceramics and a method for using the same are provided. The coloring solution consists of coloring agents, a solvent, and an additive. The coloring agents are a combination of two or more rare earth metal compounds, wherein the rare earth metal compounds having rare earth metal ions selected from the group consisting of praseodymium (Pr) ions, erbium (Er) ions, cerium (Ce) ions, and neodymium (Nd) ions. The concentration of the rare earth metal ions in the solution is 0.05˜3 mol/liter solvent. The molar ratio of Pr ions:Er ions:Ce ions:Nd ions in the solution is 1:(10˜50):(0˜20):(0˜30).
