To achieve high sintered density, hot pressing and SPS are often used. In our previous work, fully dense Ti-6Al-4V and Ti-TiC composites were successfully fabricated by vacuum pressureless sintering. The O content in the as-sintered materials was below 2000 ppm, and the N content was below 500 ppm.
Find Microwave Zirconia Sintering Furnaces related suppliers, manufacturers, products and specifications on GlobalSpec - a trusted source of Microwave Zirconia Sintering Furnaces information.
Sintering starts with debinding. The debinding process removes binder materials that can contaminate the furnace and the final product. Binding materials are originally necessary for each separate part compaction, but become unnecessary and undesirable during the sintering process. Vacuum sintering requires a high vacuum for clean, quality parts.
