What is Tantalum Carbide? Tantalum carbide powders are mainly manufactured via three methods: (1) heat treatment in a non-oxidizing atmosphere using a mixture of tantalum metal and graphite powders, (2) solid carburization, such as self-propagating high-temperature synthesis (SHS) using the reaction heat between reactants by mixing tantalum and graphite powders, and (3) gaseous carburization using hydrocarbon gases such as methane, propane, and butane as the carburizing media for tantalum. In addition, other methods, such as reduction carburization, which employs a mixture of tantalum oxide (Ta2O5) and graphite powders to simultaneously induce reduction and carburization reactions, are being studied for commercialization.
On the Synthesis of Tantalum-Carbide Powder by the Reaction of Tantalum with Toluene Tantalum carbide powders are mainly manufactured via three methods: (1) heat treatment in a non-oxidizing atmosphere using a mixture of tantalum metal and graphite powders, (2) solid carburization, such as self-propagating high-temperature synthesis (SHS) using the reaction heat between reactants by mixing tantalum and graphite powders, and (3) gaseous carburization using hydrocarbon gases such as methane, propane, and butane as the carburizing media for tantalum. In addition, other methods, such as reduction carburization, which employs a mixture of tantalum oxide (Ta2O5) and graphite powders to simultaneously induce reduction and carburization reactions, are being studied for commercialization. Among these methods, solid carburization is limited by requirements of high reaction temperatures of 2000 K or higher, difficulties in controlling product uniformity, and residual-free carbons. Furthermore, solid carburization can be hazardous due to the CO gas generated during the reaction. Meanwhile, gaseous carburization requires highly pure hydrocarbons to prevent the re-oxidation of tantalum carbide and ensure effective carburization. Commercial propane and butane are unsuitable for carburization because of their low purity, and the cost increases because many processing devices for purification are required to use these. Although high-purity methane is commercially available and is used for carburization, it is expensive and economically unfeasible. Therefore, this study aims to synthesize tantalum carbide using a hydrocarbon gas produced from liquid hexane, which is less expensive and easier to handle than the conventional methane used for carburization.
Synthesis of Tantalum Carbide Using Purified Hexane by Titanium Powder The purity of hexane commonly used in the industry is 95%, necessitating a process for removing impurities. However, there have been no reports on removing impurities from commercial hexane. For the first time, we have suggested an economically feasible method for producing TaC ceramic compound material. We purified the commercially available hexane using irregularly shaped titanium powder, which is further used to produce the high-purity TaC through gas carburization, as it can capture most of the oxygen-containing compounds that constitute most of the impurities in hexane. Therefore, the present study investigated the purification of hexane using titanium powder Anderson and recyclable metal powders such as iron, copper, and aluminum. However, the study employed magnets, to which the iron powder stuck during stirring, making it difficult to evaluate the reliability of the impurity-removal reaction. Therefore, we attempted to systematically verify the purification of hexane using titanium, copper, and aluminum powders by synthesizing tantalum carbide using a hydrocarbon gas obtained from purified hexane. Titanium was found to be more effective at the removal of oxygen-containing impurities from hexane than copper and aluminum at room temperature, and hexane purified using titanium powder was proven to yield high-purity tantalum carbide when used as a carburizing agent for tantalum.
