Abstract
A composition of matter and method of forming a radiation shielding member at ambient temperatures in which the composition of matter includes a ‘cold-fired’ chemically bonded oxide-phosphate ceramic cement matrix; with one or more suitably prepared and distributed radiation shielding materials dispersed in the ‘cold-fired’ chemically bonded oxide-phosphate ceramic cement matrix.
Claims19
A composition of matter, comprising:
- a chemically bonded oxide-phosphate based ceramic matrix;
- and a radiation shielding material, wherein the radiation shielding material is dispersed in the chemically bonded oxide-phosphate based ceramic cement matrix and the radiation shielding material is selected from the group consisting of barite, barium oxide, barium sulfate, cerium oxide, tungsten oxide, gadolinium oxide, depleted uranium oxide, annealed leaded glass 40% to 75% both powdered and fibers, zeolites, clinoptilotites, and celestites
A radiation shielding composition of matter, comprising:
- a chemically bonded oxide-phosphate based ceramic matrix having, a cation constituent, exhibiting radiation shielding capability;
- and a radiation shielding material selected from the group consisting of a powder, an aggregate, and a fiber, wherein the radiation shielding material is dispersed in the chemically bonded oxide-phosphate based ceramic matrix.
A method of constructing a radiation shielding member at ambient temperature, comprising:
- mixing a metal oxide having a radiation shielding capability with a phosphate containing material;
- incorporating a radiation shielding material into the metal oxide and phosphate containing material mix;
- curing the incorporated radiation shielding material and metal oxide and phosphate containing material mix at ambient temperature.
