Technology helps solid-state inorganic chemistry. Solid-state chemistry works to make materials used in commerce. Researchers serve industry, as well as answering academic questions. There were many important discoveries in the 20th century: zeolite and platinum-based catalysts for petroleum processing in the 1950s, high-purity silicon as a core component of microelectronic devices in the 1960s, and “high temperature” superconductivity in the 1980s. William Lawrence Bragg invented X-ray crystallography in the early 1900s, which brought further discoveries.
