A bstract The manufacturing characteristics, properties, uses, and future possibilities of zircon porcelain are discussed. Any of the usua1 manufacturing processes may be used, but special glazes must be employed because zircon absorbs normal glazes: The typical properties (approximate values) are ( a ) linear expansion, 4.5 × 10 ‐6 per °C., ( b ) thermal conductivity, 0.012 (normal porcelain, 0.004), ( c ) tensile strength, 13,000 Ib. per sq. in., ( d ) compressive strength, 100,000 Ib. per sq. in., ( e ) modulus of elasticity, 25 × 10 6 Ib. per sq. in., ( f ) thermal‐shock resistance, good, ( g ) power factor at 1 mc., 0.001, and ( h ) dielectric constant, 9.
