With the rapid expansion of photovoltaics (solar silicon wafers), semiconductors, optical fibers, high-end ceramics, electronic packaging, and advanced coatings, the requirements for quartz powder have escalated dramatically. These applications demand ultra-fine particle sizes. In many cases, D50 must be below 5 μm or even reach the sub-micron range. They also require an extremely narrow particle […]

Glass powder, as an inorganic filler, is widely used in coatings, plastics, rubber, adhesives, and many other industrial fields. Its advantages are reflected in performance enhancement, cost optimization, process compatibility, and environmental sustainability. The following is a comprehensive analysis of the advantages of glass powder as a filler. Core Performance Advantages 1. Significant Improvement in

What exactly is white carbon black, and why is it so important in modern industries? White carbon black—also known as precipitated silica, hydrated silica, or amorphous SiO₂—is a fine, white powder made from silicon dioxide. Through White Carbon Black Grinding and Modification, its particle size distribution, specific surface area, and surface activity can be precisely

Quartz powder is an important industrial raw material. It is widely used in glass, ceramics, engineered quartz stone slabs, coatings, electronic packaging, and other fields. One of its key quality indicators is whiteness, including blue-light whiteness and fired whiteness. High-whiteness quartz powder usually requires a value above 95, or even higher. Whiteness directly affects the

Silica (white carbon black), including precipitated silica and fumed silica, is a high-performance inorganic filler widely used in rubber reinforcement, coating rheology control, and transparent reinforcement of silicone rubber. Silica ultrafine grinding (typically D50 < 10 μm, and even submicron level) directly affects specific surface area, dispersibility, purity, and reinforcing performance. The most common ultrafine

Silicon micropowder is a silicon dioxide (SiO₂) powder material produced from crystalline quartz, fused quartz, and related raw materials through processes such as crushing, grinding, precision classification, and impurity removal. Classification and Characteristics of Silicon Micropowder Based on differences in particle morphology and physical structure, silica micropowder is commonly classified into crystalline silica micropowder, fused

High purity quartz sand (HPQ), typically containing SiO₂ ≥99.99% (commonly 99.997%–99.999%, or even higher), is characterized by extremely low impurity levels (especially Al, Fe, Ti, B, P, etc.), typically controlled at ppb or even sub-ppb levels. Even trace contamination can render the end products completely ineffective. Due to these characteristics, it has become one of
