Description of the Silicon Boride SiB6 :
Silicon hexaboride, chemical formula SiB6, is an inorganic compound with high hardness, melting point, resistivity and chemical stability. It is a borosilicate mineral composed of two elements: silicon and boron. The crystal structure of silicon hexaboride is a face-centred cubic structure; the cell parameters are a=0.512nm, b=0.512nm, c=0.924nm, and the crystal faces are (100), (110) and (111). It has a metallic lustre and can fluoresce blue-green under ultraviolet light. The physical properties of silicon hexaboride also include high density, high hardness, high melting point, low vapour pressure and good thermal stability. Silicon hexaboride has good thermal and electrical conductivity. In terms of chemical properties, silicon hexaboride shows good oxidation and reducibility. Under the action of an oxidizing agent, it can be oxidized to a mixture of silicon tetraboride and silicon triboride. In contrast, under the action of a reducing agent, it can be reduced to a mixture of silane and borane.
Application of the Silicon Boride SiB6 :
Electronics and Semiconductor Industry:
In the electronics and semiconductor industries, silicon hexaboride has attracted much attention due to its high resistivity, melting point, stability, and chemical inertness. It is used to make high-temperature transistors, integrated circuits and solar cells. These applications mainly take advantage of silicon hexaboride's high stability and heat resistance, enabling it to remain stable in high-temperature and strong radiation environments, thereby improving the performance and reliability of electronic devices.

In chemical sensors, silicon hexaboride can detect chemicals in gases and liquids and send corresponding electrical signals. Silicon hexaboride can be used as a catalyst carrier to combine with other elements to form a catalyst with specific catalytic properties.
In recent years, silicon hexaboride has attracted attention because of its good biocompatibility and non-toxicity and has been applied in the biomedical field. In biomedicine, silicon hexaboride is used as a drug carrier, biological imaging agent, gene carrier and tumour therapy. Among them, silicon hexaboride can be used as a carrier to adsorb drug molecules on its surface. Then, the drug is accurately delivered to the tumour and other pathological sites, thereby improving the drug's efficacy and reducing side effects. In addition, silicon hexaboride can be used as biomedical materials such as biological imaging agents and gene carriers, which has many application prospects in medical research.
Material synthesis and processing:
Silicon hexaboride has been widely used in high-temperature synthesis and processing as a kind of high-temperature resistant and chemically stable material. For example, in synthetic superhard materials, high-performance ceramics, alloys, etc., silicon hexaboride can be used as an additive or enhancer to improve the performance and stability of materials. In addition, silicon hexaboride is also widely used in optical coating, electron beam evaporation coating and other processing technologies.
Production Method of the Silicon Boride SiB6 :
Silicon and boron direct reaction method:
This method is the direct reaction of silicon and boron to synthesize silicon hexaboride under high temperature and high-pressure conditions. The specific preparation process is as follows:
(1) The powder of silicon and boron is mixed according to the stoichiometric ratio of 1:6 and fully ground to ensure the uniformity of the reaction;
(2) Put the mixed powder into a sealed steel reactor and fill it with an inert gas to prevent oxidation during the reaction;
(3) Under high temperature and pressure conditions (usually above 1200℃), silicon and boron react to produce silicon hexaboride;
(4) By controlling the reaction time and temperature, the purity and crystal structure of the generated silicon hexaboride can be controlled;
(5) Silicon hexaboride crystals are obtained through cooling and decompression operations after the reaction.
The direct react method has the advantages of simple operation and less equipment investment. Still, at the same time, there are some disadvantages, such as higher reaction conditions, high temperature and high-pressure conditions, a long reaction time, and the need for fine control. Otherwise, it will lead to defects or impure silicon hexaboride crystals generated.
Silane and borane pyrolysis method:
In this method, silane and borane are pyrolyzed to produce silicon hexaboride under high-temperature conditions. The specific preparation process is as follows:
(1) The mixture of silane and borane gas is passed into the quartz tube and heated to high temperature;
(2) At high temperatures, silane and borane undergo pyrolysis reaction to produce silicon hexaboride;
(3) By controlling the reaction temperature and time, the purity and crystal structure of the generated silicon hexaboride can be controlled;
(4) After the reaction, the silicon hexaboride crystal is obtained by cooling operation.
This method has the advantages of low reaction temperature and fast reaction speed. Still, at the same time, there are some disadvantages, such as the need to use high-purity silane and borane, high equipment requirements, and safety risks, and strict control of operating conditions is required.
Both methods can generally be used to prepare silicon hexaboride crystals; the specific choice depends on experimental conditions, equipment investment, production scale and other factors. If conditions permit, choosing the silane and borane pyrolysis method is recommended because this method has higher flexibility and adaptability.
