Method of using a high temperature ultrasonic couplant material
First Claim
1. A method of attaching an ultrasonic transducer to a metal substrate with a couplant material to produce a sound path of good acoustic impedance between the transducer and the metal substrate which includes the steps of:
- applying a non-flammable grease-like silicone fluid heavily filled with zinc oxide and which at room temperature is easily shaped between said substrate and said ultrasonic transducer, andmechanically securing said ultrasonic transducer to said substrate.

Abstract
A couplant material for establishing a sound path of good acoustical impedance between a transducer and a supporting wave-transmitting substrate which is capable of being easily shaped at room temperature, withstanding thermal cycling from room temperature to over 450° F., and substantially maintaining its acoustical properties in a radiation atmosphere while providing a minimum of irritating fumes and outgassing. The couplant material is a non-flammable, grease-like silicone fluid heavily filled with zinc oxide. It has been used previously as a heat sink compound for electronic components.
