Dental retrograde-filling material containing cobalt and process

Abstract

A dental retrograde-filling material process, comprising the steps of: taking 3:1 mole ratio of a calcium oxide and a silicon dioxide mixes a 1˜5 w.t. % cobalt oxide at 1200˜1800 degree Celsius temperature to get a A-product including a tricalcium silicate, a dicalcium silicate and a containing cobalt composition; taking 3:1 mole ratio of a calcium oxide and an aluminum oxide at 1200˜1800 degree Celsius temperature reacts a B-product including a tricalcium aluminate; taking 4:1:1 mole ratio of a calcium oxide, an aluminum oxide and a ferric oxide at 1200˜1800 degree Celsius temperature reacts a C-product including a calcium alminoferrite; and mixing the A-product, B-product and C-product are the retrograde-filling material. The dental retrograde-filling material mixes of taking 8:1:1 mole ratio of said tricalcium silicate, dicalcium silicate and containing cobalt composition, tricalcium aluminate and calcium alminoferrite.
