Process for producing boron nitride

The present invention provides a wave absorber holding both nonflammability and flexibility and having advantageous properties regarding the lightness in weight, the thermal insulation, the sound insulation, the sound isolation, and the workability to ensure a certain freedom in shaping. Each of wave absorbing materials A , A , and A given as embodiments of the present invention include a conductive filler, an inorganic endothermic filler, and an organic binder as main constituents. A wave absorber A for wave anechoic rooms and semi-wave anechoic rooms is prepared by using any of these wave absorbing materials A , A , and A

Radio wave absorbing materials, radio wave absorber, and radio wave anechoic chamber and the like made by using the same

The present invention attains a microwave absorber attachment in a readily, rapidly and stable manner. According to the microwave absorber attaching method and structure of the present invention, a plurality of ferrite plates are bonded to a shield plate at an installation place such as the ceiling, a wall, the floor or the like; the base portion of a support rod is connected to the ferrite plates , causing the support rod to project therefrom; a microwave absorber is placed with its base portion placed along the ferrite plates ; the support rod 6 passes through a tip opening of the microwave absorber , causing the support rod to project therethrough; a covering tray allows for the support rod to pass therethrough to cover the microwave absorber ; and a fastening member is fastened to a tip threaded portion of the support rod , thus attaching the microwave absorber to the installation place. The gaps between adjacent ferrite plates are filled with a magnetic sealing agent.
