The Okayama Ceramics Research Foundation (OCRF) and others published a report(1) on “the basic characteristic analysis of mass-produced Al4SiC4” in the “Taikabutsu” issued by the Technical Association of Refractories.
Since the aluminium silicon carbide Al4SiC4 has an interesting feature, it is drawing attention as new functional materials in the fields of high temperature materials and refractory raw materials etc.
In this report, they reported the analysis results of chemical composition, mineral composition, particle appearance, true density and particle size as characteristics of raw material Al4SiC4 powder.
In addition, they prepared a dense sintered compact using Al4SiC4 then evaluated and reported its hardness, thermal expansion and thermal conductivity.
From the analysis results above, they concluded that mass-produced Al4SiC4 is a product with basic characteristics equivalent to the literature values that was reported in previous research.
Though a mass production of Al4SiC4 had not been achieved before, OCRF and Tateho Chemical Industries established the mass production process as a result of our collaborative research.
In December 2017, TATEHO launched “REFTAT® AC-1” onto the market.

Tateho’s REFTAT® AC-1 (Aluminium silicon carbide, (Al4SiC4) has a high melting point of 2037 °C. This is a material stable in a wide range of temperatures and has excellent water resistance.
