Title:
METHOD OF MANUFACTURING SILICON CARBIDE-CONTAINING HEAT STORAGE MATERIAL FROM WASTE SILICON SLUDGE
Document Type and Number:
WIPO Patent Application WO/2012/165841
Kind Code:
A3
Abstract:
Provided a method of method of manufacturing a silicon carbide-containing heat storage material, including the steps of: providing a silicon sludge produced from a silicon wafer cutting process; heat-treating the silicon sludge in a non-oxidative atmosphere to remove a part of oil; mixing the silicon sludge with a binder to prepare a slurry; extruding the slurry to form a honeycombed compact; and reaction-sintering the honeycombed compact at a temperature of 1300 ~ 1900℃ in a non-oxidative atmosphere. The method is advantageous in that a silicon carbide-containing heat storage material having high thermal conductivity, heat accumulation characteristics and chemical resistance can be manufactured at a low cost.
