摘要	IMPACT STATEMENT The first multicomponent gamma-type RE2Si2O7, (Gd1/6Tb1/6Dy1/6Tm1/6Yb1/6Lu1/6)(2)Si(2)O(7)with outstanding phase stability is developed. It presents the possibility to design complex oxide through the 'one-from-none' strategy. A multicomponent rare-earth disilicate (Gd1/6Tb1/6Dy1/6Tm1/6Yb1/6Lu1/6)(2)Si(2)O(7)has been designed and successfully synthesized following the strategy of high entropy engineering. The as-prepared single-phase 6RE-disilicate possesses a new gamma-type crystal structure (monoclinic,P2(1)/c) beyond the alpha-, beta- and delta-type parent structures of six single RE disilicates. Six-species RE cations are homogeneously distributed on RE lattice sites and our multicomponent disilicate demonstrates outstanding thermal stability from room temperature up to around 1900 degrees C. This work extends the knowledge of strategic multicomponent modification of complex ceramics with extremely high phase stability.
