This leads to the conclusion that within the range of sintering temperatures lying between the temperature securing a sufficient quantity of the liquid phase and the temperature of overburning (both depend on the cobalt content), no effects except grain growth occurs if there is an adequate protection against the action of the furnace atmosphere.

2014-1-3 · Tungsten Powder Metallurgy - Sintering is commonly regarded as taking place in three stages： *During the early stage, necks are formed between individual particles and grow by diffusion, increasing the interparticle contact area. The powder aggregate shrinks, involving center to center approach of the particles.

Silicon carbide heating elements surround the chamber sides and are protected by silicon carbide tiles. The hearth is constructed from refractory bricks and silicon carbide tiles. The SCF 1 has a single chamber, all other smelting furnace models have twin chambers with separate lids. Carbolite also offers a range of cupellation/fire assay furnaces.

In our past article, we provided an overview of the material known as Tungsten Carbide.In this follow up, we'll tell you how this key material is made. Tungsten has the highest melting point of all metals, at 3410 o C (6170 o F). In order to create parts made from tungsten or tungsten alloys like tungsten carbide, the typical process of melting and blending of the metal and alloying elements
