Abstract
This paper focuses on making a novel Lanthanum Phosphate-based durable and cost-effective crucible for high temperature applications such as fabrication processes of advance functional materials. A crucible is designed and fabricated by using three parts die following by powder metallurgical technique. Stepwise sintering was used to sinter the crucible. The synthesized crucible was then exposed to several tests to assess its structure, surface topography, durability, thermal expansion, and thermal shock resistance. Thermogravimetric analysis revealed a smaller mass loss of about 9.7%. Scanning electron microscope (SEM) analysis showed a spherical structure with pores enough to make a compact structure. It is also observed that the Lanthanum Phosphate-based crucibles have high non wettability after pouring out the molten magnesium and found thermal shock resistant. Interestingly, the crucible retained its original shape without failure up to 4 cycles. These results show that the synthesized Lanthanum Phosphate-based crucible is promising for high temperature applications.
