Physical Properties of Sonite.

Abstract

Sonite, a highly porous, particulate, fiber-reinforced, ceramic material used in acoustics, was studied to: acquaint potential users with methods of handling and fabrication; determine useful mechanical, electrical and acoustic properties. Sonite is a solid material which is capable of being handled and fabricated into intricate shapes and parts, with a modest amount of care, using conventional techniques. Tested under various load conditions, the product, after being 'prestressed,' exhibited basically elastic mechanical-acoustical properties, up to the 'prestress' limit. The velocity of sound propagation and the acoustic impedance were both linear and of very low magnitude when compared with water. The above mentioned properties were not affected by variations in temperature lower than ambient (4-30C). Sonite also showed a low modulus of elasticity and a low mechanical damping capacity for a ceramic material of high porosity. (Author)
