SiS2 powder is supplied in vacuum-sealed bottles to protect the material from moisture during transportation and storage. Custom packaging is available upon request.
Store in a cool, dry, and well-ventilated place with the container tightly sealed. Avoid exposure to moisture, as silicon disulfide readily hydrolyzes and may release hydrogen sulfide (H₂S).
Q1: What is silicon disulfide powder used for?
It is primarily used in scientific research, solid-state chemistry, sulfide material synthesis, and advanced materials research.
Q2: What purity grades are available?
We supply silicon disulfide powder with standard purities of 99.99% (4N) and 99.999% (5N). Customized specifications are available upon request.
Q3: Is silicon disulfide moisture sensitive?
Yes. It reacts with moisture and should be stored in tightly sealed containers in a dry environment.
Q4: Can you provide customized packaging or specifications?
Yes. We offer customized purity, packaging, and other specifications based on customer requirements.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
