Title: Larry E Campbell: Innovator in Silicate Coatings and Glass Hydration

Introduction

Larry E Campbell is a notable inventor based in Corning, NY (US), recognized for his contributions to the field of silicate coatings and glass technology. He holds 2 patents that showcase his innovative approaches to enhancing the durability and properties of silicate materials.

Latest Patents

One of his latest patents is titled "Method for making chemically durable silicate coatings." This invention focuses on producing chemically durable inorganic silicate coatings that are homogeneous, easy to apply, and exhibit essentially infinite shelf life. The method involves incorporating a metal oxide into an aqueous solution of an alkali metal silicate, primarily consisting of potassium, which dries in air and is non-hygroscopic. Upon drying and curing, a crystal phase precipitates within the solution, leading to a durable coating with a crystal phase homogeneously dispersed in a silicate glassy matrix.

Another significant patent by Campbell is "Hydration of silicate glasses in aqueous solutions." This invention describes a method for hydrating fine-dimensioned alkali metal-containing silicate glass bodies to impart thermoplasticity. The process involves contacting these glass bodies with an aqueous solution at elevated temperatures and pressures, resulting in a surface layer with a water content of up to about 36% by weight. This innovation allows the hydrated bodies to exhibit properties similar to high-polymer organic plastics and enables thermoplastic forming at relatively low temperatures.
