## Description

- description: "This paper describes the detailed high-temperature properties of monophasic
    Al3BC3, including\r\nthe thermal expansion characteristics of its crystal structure
    and thermal shock resistance.\r\nWe examined the differences in physical properties
    between Al3BC3 and Al8B4C7, which was\r\npreviously thought to be Al3BC3. Compared
    with the thermal conductivity and CTE of Al3BC3\r\nmeasured in the present study,
    those reported for Al8B4C7 in a previous study were higher,\r\nwhich is attributable
    to residues of Al and B. The densification of Al8B4C7 is supported by gasphase\r\ndiffusion
    via Al- and B-based gases or liquid, whereas the sintering of Al3BC3 is dominated\r\nby
    solid-phase diffusion. The bending strength of Al3BC3 was 226 MPa at RT and was\r\nmaintained
    even at high temperatures. Al3BC3 was found to exhibit a good thermal shock\r\nfracture
    resistance parameter R’ of 3.3, equivalent to that of Al2O3 and substantially
    better than\r\nthat of commonly used engineering ceramics Al4SiC4 and Al6Si2O13,
    mainly because of the\r\nhigher thermal conductivity and lower elastic modulus
    of Al3BC3. The dense Al3BC3 sample\r\nexhibited excellent thermal stability under
    N2 and inert gas atmospheres but was easily\r\noxidized to monophasic Al2O3 at
    1300°C under ambient air."
