Title: CERAMIC MATERIAL FOR RADOME, RADOME AND PROCESS FOR THE PRODUCTION THEREOF
Abstract:
A ceramic material for radome is illustrated comprising: - about 80-95% (%wt) of Si3N4; about 5-15% (wt%) of magnesium aluminosilicates including 2.5-12.5% (wt%) of Si02, 0.5-3% (wt%) of MgO and 2-6% (wt%) of A1203; and having a density not lower than 2.5 g/cm3 and a dielectric constant not exceeding 6.5. A process for producing a radome is also illustrated.
