Title: The Innovations of William A. Belding

Introduction

William A. Belding is a notable inventor based in Pleasanton, CA (US). He holds 2 patents that showcase his contributions to materials science, particularly in the fields of alumina and flame-retardant fillers.

Latest Patents

One of his latest patents is for "Alumina of high macroporosity and stability." This invention involves a calcined and shaped alumina that exhibits a stabilized, high pore volume and a low surface area, along with high strength. The alumina is derived from materials such as pseudoboehmite or chi-rho-eta alumina. The stabilized product demonstrates a total porosity of at least about 0.4 cc/g and a surface area ranging from about 2-20 m²/g. The porosity is stabilized through treatment with a combination of silica and an inorganic fluoride prior to calcination. This stabilized alumina can be effectively used as an adsorbent or catalyst support, especially in high-temperature applications.

Another significant patent is for "Bauxite as flame-retardant filler for polymer compositions." This invention focuses on making bauxites compatible with polymer compositions used in the carpet industry. The suitable bauxites are characterized by a surface area of less than about 12 m²/g, a pH in aqueous suspension of more than about 6.5, and a particle size distribution where less than about 15% by weight of the particles are smaller than 3 microns. Bauxites with a surface area between 12-20 m²/g can also be modified to enhance compatibility with polymer compositions.
