Abstract
The present invention is related to a family of materials that may act as a replacement for lead in applications where the high density of lead is important, but where the toxicity of lead is undesirable. The present invention more particularly provides a high density material comprising tungsten, fiber and binder. Methods and compositions of such materials and applications thereof are disclosed herein.

A high density composition of matter, comprising:
- a. tungsten powder;
- b. stainless steel fiber;
- and
- c. a binder.
A high density composition of matter, comprising:
- tungsten powder, wherein the tungsten powder comprises a first group of particles having sizes of between about 2 microns and about 8 microns, and a second group of particles having sizes of between about 20 microns and 40 microns;
- and
- a binder.
A high density composition of matter, comprising:
- a. tungsten powder;
- b. a fiber, wherein the fiber comprises at least one of tungsten fibers, copper, nickel, niobium, Kevlar.RTM., Spectra.RTM., graphite, boron, cellulose or cotton;
- and
- c. nylon 12.RTM..
A radiation shielding material made from a high density composition of matter, the composition comprising:
- a) tungsten powder, wherein the tungsten powder comprises a first group of particles having sizes of between about 2 microns and about 8 microns, and a second group of particles having sizes of between about 20 microns and 40 microns;
- and
- b) a polymeric binder.
A high density composition of matter, comprising:
- tungsten powder, wherein the tungsten powder comprises a first group of particles having sizes in a first range, a second group of particles having sizes in a second range, and a third group of particles having sizes in a third range;
- and
- a binder.
