“…Examples of well known additives are mixtures of Al 2 [2][3][4]9,10] . Among the aforementioned rare earth oxides, the one best known for production of the liquid phase during sintering is Y 2 O 3 , which appears in numerous publications [1][2][3][4][5][6][7][8][9][10][11][12][13] . Yttrium is one of the four most abundant rare earths and dysprosium and ytterbium occupy the eighth and ninth place 13,14 .…”

“…SiC ceramics have many applications because they allow the combination of important properties such as low density, high elastic and rupture modulus, high thermal shock resistance, and high resistance to corrosion and oxidation at high temperatures [1][2][3][4][5][6][7][8][9][10][11][12][13] . One of the properties of SiC ceramics that limits many applications is their low fracture toughness.…”

“…The sessile drop technique is one of the most used experimental procedures for this purpose, as with a photographic system, images of the solid substrate + sample that will be melted (giving rise to the liquid phase when increasing the temperature) can be obtained, leading to an accurate determination of the shape evolution of the molten component. The contact angle is further calculated with an appropriate image analyzing software 7,[17][18][19] .…”

“…Com um sistema fotográfico registrando imagens do conjunto substrato sólido (base) + material a ser fundido (que dará origem a fase líquida à medida que a temperatura aumenta) é possível acompanhar a evolução da forma da amostra, exatamente antes e depois da fusão. O ângulo de contato é então medido usando um programa computacional (13)(14)(15)(16)(17)(18)(19)(20) . (25) .…”

“…A temperatura de fusão de cada mistura foi obtida a partir das imagens capturadas e de acordo com a norma DIN 51730 (16) . Em trabalhos anteriores não foi possível medir o ângulo de contato de misturas de terras raras quando se utilizou atmosfera de nitrogênio devido à formação de bolhas (13,18,19) . Portanto, assim como foi adotada para o teste de molhabilidade, foi também adotada para a sinterização do SiC aditivado, a atmosfera de argônio a 1 atm.…”
