摘要:
A process for manufacturing a sintered ceramic composite, based on silicon nitride and β-eucryptite, includes a step of producing a first powder blend, consisting of a powder of silicon nitride in crystalline form and a powder of a first lithium aluminosilicate in crystalline form, the composition of which is the following: (Li2O)x(Al2O3)y(SiO2)z, the lithium aluminosilicate composition being such that the set of molar fractions (x,y,z) is different from the set (1,1,2).

摘要:
A composite having a coefficient of thermal expansion less than 1.3×10−6 K−1 is a sintered ceramic based on an oxide and on β-eucryptite crystals having a β-eucryptite content of less than 55% by weight (69% by volume).
