SILICON GRANULATE FOR SILICIFICATION OF BUILDING ELEMENTS MADE OF CARBON OR MIXTURES OF SILICON CARBIDE AND CARBON, PROCESS FOR PRODUCING SUCH GRANULATE AND PROCESS FOR PRODUCING SILICON-INFILTRATED BUILDING ELEMENTS OF SILICON CARBIDE

摘要

The proposed process for producing structural element from silicon infiltrated silicon carbide is characterized in that shaped bodies of carbon or a mixture of silicon carbide and carbon are put onto a burning furnace baking plate a by baking they are infiltrated with silicon, wherein silicon granulate is used as a silicon source. Said silicon granulate particles are provided with a coating that contains carbon or a carbon-releasing compound, a binding agent and boron nitride.
