Web4 jul. 2024 · These substances are extremely hard, have high melting points, and are chemically inert. For example, silicon carbide is highly resistant to chemical attack at temperatures as high as 1600°C. WebPZT was developed around 1952 at the Tokyo Institute of Technology. PZT is composed of the two chemical elements lead and zirconium combined with the chemical compound titanate. PZT is formed under extremely high temperatures. The particulates are filtered out using a mechanical filter. PZT causes a compound to change shape from an electric field.
