FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy. Shell is formed at pattern unit using the silica sol binder, refractory filler and spray material. Shell plies are dried and pattern compound is melted out in hot water. To produce first ply or two first plies suspension is used including the following components in vol. %: acid silica sol - 37-41 and fused quartz - 59-63. To make the next plies suspension is used containing the following components in vol. %: basic silica sol - 36-44 and fused quartz - 56-64.
EFFECT: higher strength of ceramic shells.
