Obtaining a ceramic refractory coating based on ethyl silicate

Molds made from refractory coating based on ethyl silicate are used in industry for the production of complex and precise castings weighing from several kilograms to several tons with curvilinear explosions from difficult-to-machine materials, as well as ordinary ferrous and non-ferrous alloys. Castings are made in ceramic molds with or without machining allowances.
