硫酸バリウムは二酸化チタンの代替となり得るか？
The main white pigments used in coatings include titanium dioxide, lithopone, and zinc oxide. Titanium dioxide is divided into rutile and anatase, each with different crystal structures. Rutile titanium dioxide has a dense structure and excellent weather resistance. Anatase is more prone to powdering when used outdoors. Lithopone tends to darken and powder easily due to the presence of zinc sulfide. Zinc oxide is an active pigment. It can cause gelling in water-based coating systems. The main purpose of white pigments in coatings is to provide opacity (covering power). The uniform distribution of titanium dioxide particle size impacts the opacity and color reduction of the coating. Precipitated barium sulfate cannot […]

Basalt, one of the most common volcanic rocks on Earth, has become a hotspot of geological research due to its unique properties and wide range of applications. This article will provide a detailed exploration of basalt from multiple dimensions, including its basic information, formation process, and main uses, unveiling the mysteries of basalt. Basic Information of Basalt Basalt is a basic extrusive rock formed when magma from a volcanic eruption cools and solidifies on the surface. It is a type of igneous rock with a dense or foamy structure.Basalts often has a porous, almond-shaped, or porphyritic texture, sometimes containing large mineral crystals. Unweathered basalt is mainly black or gray, but […]
シリコン系陽極材料製造のための主要設備
In the production process of silicon-based anode electrodes, special equipment selection and configuration directly affect product quality and production efficiency. Compared with traditional graphite negative electrode production, silicon-based anode electrode production equipment has higher technical requirements. It also has stricter control accuracy. Silicon-oxygen and silicon-carbon negative electrodes have different process characteristics. Their core equipment also differs to some extent. But some general equipment can be shared. The following will detail key equipment and technical characteristics in silicon-based negative electrode production. The Sublimation Furnace System The sublimation furnace system is the core equipment for preparing silicon-oxide anode precursors. It is primarily used for synthesizing silicon monoxide (SiOx). Modern sublimation furnaces typically […]
エネルギー貯蔵に革命を起こす：シリコン酸素アノードのための最先端の製造プロセスと装置
Silicon-oxygen anodes are an important branch of silicon-based anodes. Their production process has unique technical characteristics and requirements. The core raw material is silicon monoxide (SiOx). Its preparation and processing form the foundation of the entire production process. Silicon-oxygen anodes can be classified into three types: regular, pre-magnesium, and pre-lithium. Each type has a different focus in its production process. Preparation of Silicon Monoxide Precursors The preparation of silicon monoxide (SiOx) precursors is the primary step in producing silicon-oxygen anodes. The industrial method for producing SiOx mainly uses high-temperature sublimation. Photovoltaic waste silicon powder and quartz sand are mixed in a weight ratio of 1:1.2 to 2. This mixture is […]
炭素材料の主な3つのカテゴリーとは何ですか？
Carbon is a magical element. As a fundamental building block, it serves as the skeleton element of all living organisms on Earth and is the most important element in the human body. Carbon materials are also unique in their ability to combine opposites and unity. They can be as thin as a hair, as light as a feather, and stronger than steel. Carbon materials are both insulators and conductors, both heat-insulating and heat-conducting, and both fully light-absorbing and fully light-transmitting. This versatility makes carbon materials ever-changing and one-of-a-kind in their properties and applications. The Difference Between “Charcoal” and “Carbon” Carbon refers to materials, which are solid substances with carbon as […]
タルク原石から粉末製品まで―完全概観
Talc is a phyllosilicate mineral, a hydrated magnesium silicate. Pure natural talc is rare, and most of it is accompanied by other mineral impurities. Common associated minerals include chlorite, serpentine, dolomite, tremolite, and calcite. Talc is usually white, light green, slightly pinkish, or light gray in color. The more impurities it contains, the darker the color, ranging from dark gray to black. The talc mineral often appears in foliated, fibrous, or dense block forms, with a pearly or greasy luster. Its Mohs hardness is 1, and its density is about 2.7 g/cm³. Talc has a slippery feel and exhibits a significant thermal effect when heated. It loses adsorbed water between […]
魔法のようなミクロの世界――PMMAマイクロビーズ
PMMA microspheres are tiny spheres made of polymethyl methacrylate (PMMA). PMMA is a thermoplastic （also as known as acrylic or plexiglass) with high transparency, good processing performance, strong weather resistance and excellent chemical stability, and is widely used in many fields. Preparation Method of PMMA Microspheres Emulsion Polymerization Under the action of the emulsifier, the monomer is dispersed in the water phase to form an emulsion. Then the polymerization reaction is carried out under the action of the initiator. In the emulsion polymerization of MMA, the emulsifier molecules form micelles in the water phase. The monomer is dissolved in the micelles, and the initiator decomposes in the water phase to […]

Bentonite is an important natural mineral resource. It is widely used in many industrial fields such as petroleum drilling, casting, environmental protection, agriculture, and chemical processing. This is due to its unique swelling properties, adsorption capacity, and multifunctionality. The main component of bentonite is montmorillonite. However, bentonite can be classified into several types. These types differ in mineral composition and chemical properties. Each type has distinct performance characteristics. This makes them suitable for various applications. This article provides a detailed introduction to the basic properties, classification, applications, and some special types of bentonite.
