Product Description

Application
Silicon carbide is a kind of carbide accidentally discovered by American Acheson in the laboratory during the electrofusion diamond experiment in 1891. At that time, it was mistakenly regarded as a mixture of diamonds, so it was named emery. In 1893, Acheson developed the method of industrial smelting silicon carbide, that is, the Acheson furnace, which has been used until now. The resistance furnace with carbon material as the core body, The mixture of silica and carbon is electrically heated to produce silicon carbide. Several events about silicon carbide
Silicon carbide was first discovered in meteorites in 1905.
In 1907, the first silicon carbide crystal led was born.
In 1955, with a major breakthrough in theory and technology, Lely proposed the concept of growing high-quality carbonization, and since then SiC has been regarded as an important electronic material.
In 1958, the first world silicon carbide conference was held in Boston for academic exchanges.
In the 1960s and 1970s, silicon carbide was mainly studied by the former Soviet Union. By 1978, the grain purification and growth method of "Lely improved technology" was first adopted.
From 1987 to now, silicon carbide production lines have been established based on the research results of Cree, and suppliers have begun to provide commercialized silicon carbide bases.
