Title: The Innovative Contributions of Menahem B Ratzker
Introduction
Menahem B Ratzker, an accomplished inventor based in Silver Spring, MD, holds a significant portfolio of four patents. His work primarily focuses on advancements in materials science, particularly in the realm of cold welding and composite materials tailored for dental applications.
Latest Patents
Ratzker's most recent patents include groundbreaking innovations in acid-assisted cold welding and intermetallic formation. This process involves creating a metallic composite solid that comprises various alloys and intermetallics. By compacting a mixture of powder particles, foils, or sheets at moderate pressures near room temperature, Ratzker's technique circumvents the need for low melting metals such as mercury, indium, or gallium as sintering agents. The low-temperature consolidation enhances the formation of these composites by either removing the surface oxide of the powder particles before consolidation or by coating them with an oxide-replacing metal like silver or gold. The addition of liquid acids, including fluoroboric acid and sulfuric acid, facilitates this innovative process. Ratzker's techniques are particularly effective for crafting dental restorative materials under controlled manual conditions.
