摘要: Abstract Silica ceramics with low porosity, high strength, dielectric constant and loss were fabricated by gelcasting using a low-toxicity N′N-dimethyl acrylamide (DMAA) gel system. Effect of solid loading on rheological properties slurries, green bodies sintered investigated. The suspension that can meet requirements for casting is as 68 vol%. However, it found the highest flexural strength 15.4 MPa 67.4 MPa obtained at 64 vol% 66 vol%, respectively. Ceramics 3.27 lowest (1 MHz) 7.82×10 –4 are 64 vol%. Solid has critical effect silica bodies.
