Chemically Bonded Phospho-Silicate Ceramics

US Patent:

6518212, Feb 11, 2003

Filed:

Sep 18, 2000

Appl. No.:

09/664490

Inventors:

Arun S. Wagh - Orland Park IL
Seung Y. Jeong - Westmont IL

Assignee:

The University of Chicago - Chicago IL

International Classification:

C04B 35447

US Classification:

501111

Abstract:

A chemically bonded phospho-silicate ceramic formed by chemically reacting a monovalent alkali metal phosphate (or ammonium hydrogen phosphate) and a sparsely soluble oxide, with a sparsely soluble silicate in an aqueous solution. The monovalent alkali metal phosphate (or ammonium hydrogen phosphate) and sparsely soluble oxide are both in powder form and combined in a stochiometric molar ratio range of (0. 5-1. 5):1 to form a binder powder. Similarly, the sparsely soluble silicate is also in powder form and mixed with the binder powder to form a mixture. Water is added to the mixture to form a slurry. The water comprises 50% by weight of the powder mixture in said slurry. The slurry is allowed to harden. The resulting chemically bonded phospho-silicate ceramic exhibits high flexural strength, high compression strength, low porosity and permeability to water, has a definable and bio-compatible chemical composition, and is readily and easily colored to almost any desired shade or hue.
