Silicon Nitride: What Is It?

Silicon nitride was first prepared in 1857 and was little more than a chemical curiosity. However, as its benefits became known, the compound began to be used across multiple industries in the late 1940s. Today, it’s a key component in electronics, turbo machinery, bearings, and even orbital satellites.

Our founders discovered that silicon nitride is stronger than bone and PEEK (polyaryletheretherketone), accepted by the human body, and compatible with all imaging technologies. These promising findings led to the development of a proprietary composition of silicon nitride. It’s antipathogenic, non-toxic, and well-suited for medical device applications.

What Makes it Different?

Silicon nitride is antiviral and antibacterial. Recent studies have proven silicon nitride AP² powder kills SARS-CoV-2 faster than other antipathogenic materials. As a biomaterial, it also offers more advantages than titanium or PEEK.
