INVESTMENT COMPOUND FOR MOULDING TECHNICS IN DENTAL TECHNOLOGY, USE OF INVESTMENT COMPOUND AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to an investment compound for moulding technics in dental technology comprising sand and a binding agent wherein the binding agent contains monoammonium phosphate (MAP) and magnesium oxide (MGO), as well as use of the investment compound and a method for the production of said compound. With known investment compounds in dental technology a long preheating period is required for the moulding muffle, which is produced with the compound, in order to reach a final temperature at which the moulding muffle can be cast. According to the invention an investment compound is created and can be placed directly in a pre-warmed furnace at a final temperature above 900 DEG C without causing any damage to the moulding muffle. A method for the production and use of the embedding compound are also disclosed.
