Exploration company Geodex Minerals recently reported the results from three of six holes drilled on its Dungarvon property in New Brunswick.

Of the holes drilled, the best is “DU-13-03". Geodex Minerals is currently exploring the Peaked Mountain target at Dungarvon.

Where it was able to locate the source of numerous large and high-grade tungsten-molybdenum bearing boulders, as well as tungsten-tin soil anomalies.

Cadillac  Ventures  is not a household name when it comes to tungsten. The Canadian exploration company has been primarily focusing its efforts on copper13 in Ontario.

However, Cadillac  Ventures  does hold a 51-percent interest in a tungsten property in New Brunswick called Burnt Hill.

The Burnt Hill project is a tungsten-tin14 mine that was brought to test production in the 1980s; currently, Cadillac is working on resuming development at the project.

Recently, Cadillac released an update15 to the resource estimate at the property filed in 2009. From the new report, the indicated tungsten resource at  Burnt Hill has seen an increase of 282 percent.

Bringing the number to 1,761,000 indicated tonnes of 0.292-percent WO3, 0.007-percent MoS2 and 0.008-percent SnO2.

The resource estimate has also seen an increase to the inferred category of 158 percent for a total of 1,520,000 inferred tonnes of 0.263-percent WO3, 0.008-percent MoS2 and 0.005 -percent SnO2 .

Nanoparticles exhibit unexpected behavior that cannot be achieved with basic elements in their original states. These unexpected properties of nanoparticles have expanded their applications to the field of cosmetics, biomedicine, electronics, etc. This article will look into the properties and applications of tungsten carbide-cobalt nanoalloy.

Tungsten carbide-cobalt is an alloy of hard, ceramic tungsten carbide and the ductile cobalt, often known as cemented carbide. The material is a metal matrix composite, in which cobalt particles are ambedded in a tungsten carbide matrix. The tungsten carbide can form as WC or WC2, depending on synthesis conditions. Cobalt content varies from around 1% to 30% by weight, depending on application.

Some of the noteworthy properties of this alloy are strength, hardness, high electrical and thermal conductivity and high malleability and ductility. Tungsten is a Block D, Period 6 element, cobalt is a Block D, Period 4 element and carbon is a Block P, Period 2 element. These particles are available in a variety of forms such as ingots, foils, sputtering targets and plates.

The chemical properties of tungsten carbide-cobalt nanoparticles are as per the table below.

Tungsten carbide-cobalt nanoparticles appear as a black powder having nearly spherical morphology. The physical properties are as below.

The thermal properties of tungsten carbide-cobalt nanoparticles are provided in the table below.

Some of the applications of tungsten carbide-cobalt are given below:

For press and sintering purposes
Making of chip-less forming tools
Mixed with coatings to enhance their hardness and strength
Production of mining, cutting tools and other wear resistant machine parts.
