Silicon composition

摘要

This invention provides a silicon composition comprising at least 15 wt % of hydrolysed silicon compounds and at least 3 wt % of a binder material. The silicon composition is used in the manufacture of ceramics. The hydrolysed silicon compounds can for example be the gel produced by hydrolysing higher boiling point organohalosilanes produced in the manufacture of organohalosilanes or halosilanes by the direct process.
