US Patent:

44889089, Dec 18, 1984

Filed:

Jan 24, 1983

Appl. No.:

6/460679

Inventors:

John D. Goodwin - Shreveport LA
Forrest W. Mulkey - Plain Dealing LA

Assignee:

Molly Maguire, Inc. - Shreveport LA

International Classification:

C04B 3100

US Classification:

106 75

Abstract:

Disclosed is a process for making a lightweight silicate aggregate. The process includes the steps of mixing together dry rice hull ash, an alkali metal hydroxide, boric acid, and water; heating the mixture to a temperature sufficient to initiate reaction; curing the composition at a temperature less than the boiling point of water until the reaction is complete; comminuting the cured product and heating the comminuted product to form the expanded aggregate.

US Classification:

501 85

Abstract:

Disclosed is a lightweight silicate aggregate produced by the steps of mixing together dry rice hull ash, an alkali metal hydroxide, boric acid, and water; heating the mixture to a temperature sufficient to initiate reaction; curing the composition at a temperature less than the boiling point of water until the reaction is complete; comminuting the cured product and heating the comminuted product to form the expanded aggregate. The expanded aggregate is useful as, inter alia, a sorbent, filler, energy insulator or filter.
