Multifunctional Applications of Microwave Experimental Furnaces

Multifunctional Applications of Microwave Experimental Furnaces: An Excellent Tool for Enterprise and Research Institution Experiments

I. Technical Advantages of Microwave Small Equipment Heating Applications:

Microwave heating is a non-contact internal heating method, meaning the material heats up uniformly from within. Microwave heating technology features rapid heating, selectivity, catalytic properties, non-direct contact between the heat source and material, ease of automation, and energy efficiency. Therefore, the microwave experimental furnace is a standardized, multifunctional microwave high-temperature experimental equipment. It is easy to operate, fast-acting, and greatly facilitates experimental exploration of different materials and scientific determination of processes. It is mainly suitable for experiments on various powders and products such as metal oxides, non-metallic materials, polymer materials, electronic ceramic powders, power battery materials, and molecular sieves for petrochemical applications. It is also used for sintering experiments on industrial new materials, electronic ceramics, special ceramics, traditional ceramics, refractory materials, and more. It can be used with protective gases, weakly reducing gases, air, oxygen-enriched air, and under micro-positive pressure conditions. It features fast sintering speed, high efficiency, and a wide range of applications.

The microwave experimental furnace is suitable for organic synthetic chemistry, pharmaceutical chemistry, food science, inspection and epidemic prevention, industrial chemistry, molecular biology, analytical chemistry, inorganic chemistry, petrochemicals, materials science, biomedical science, and other related fields. This instrument has significant application value in the above fields, inducing or accelerating chemical reactions and physical processes through enthalpy and entropy effects, making reaction speeds hundreds or even thousands of times faster than conventional methods. It also improves reaction selectivity and yield, making many previously difficult or slow chemical reactions or physical processes easy to achieve and complete at high speeds. It is mainly used for high-temperature sintering, research and development, and small-batch production of various materials in universities, research institutions, and enterprise technology R&D centers.

II. Multifunctional High-Temperature Technical Features of Microwave Experimental Furnaces:

The microwave experimental furnace operates by the material itself (powder, granules, blocks, sheets, columns, or other small items of any shape) absorbing microwave thermal energy. Microwaves are extremely high-frequency electromagnetic waves. In a microwave field, polar and non-polar molecules within the material become polarized, turning into dipole molecules. These dipoles align with the electric field direction. Since the electric field is alternating, the dipoles rotate and vibrate accordingly. For example, at a frequency of 2450 MHz, they rotate and vibrate 2.45 billion times per second, generating an effect similar to molecular friction, thereby absorbing the electric field's energy and generating heat. The material itself becomes the heat source. Thus, microwave heating involves the material heating uniformly from within. In contrast, traditional coal, electricity, oil, and gas kilns have high energy consumption, pollution, and exhaust emissions. Their heating method is external heat conduction, from the surface inward, resulting in long heating times, low thermal efficiency, a tendency for coking, and the need for regular cleaning, shutdown maintenance, and frequent replacement of components.

III. Microwave Experimental Furnace Series Models and Functions:

The multifunctional microwave series equipment meets various microwave energy application needs, from low to high temperatures, atmospheric to vacuum conditions, multiple atmospheres, and batch to continuous processes. It is suitable for drying, sintering, roasting, calcining, synthesis, thermal reduction, ashing, pyrolysis, carbonization, expansion, heat treatment, curing, crystallization, catalysis, and more. Developed furnace types include: microwave push-plate kilns, microwave roller hearth kilns, microwave steel belt kilns, microwave annular kilns, microwave tunnel kilns, microwave rotary kilns, and others. Experimental equipment has been standardized and produced, forming standardized series such as: 1600°C vacuum sintering furnaces, 1600°C microwave atmosphere experimental furnaces, microwave tube furnaces, microwave muffle furnaces, microwave pyrolysis furnaces, microwave rotary furnaces, microwave expansion furnaces, microwave-electric hybrid heating furnaces, microwave hot-press sintering furnaces, and more. These are applied in mineral processing, metallurgical powders, coal chemical industry, petrochemicals, rubber chemicals, ceramics, building materials, new material sintering, food, pharmaceuticals, agricultural product processing, forest product processing, drying and dehydration of new chemical materials, industrial solid and hazardous waste treatment, and many other industries.

Specific Application Areas of Microwave Experimental Furnaces:

1. Synthesis and calcination of various inorganic powders (carbides, nitrides, electronic ceramic powders, phosphors, lithium-ion battery materials, various ceramic pigments, glazes, ceramic raw materials, hydroxides, inorganic salts, etc.)

2. Sintering of various inorganic material products/devices (electronic ceramics, biomedical ceramics, daily-use ceramics, honeycomb ceramics, art ceramics), ashing, incineration

3. Carbothermal reduction of metal oxide ores (drying, pyrolysis, roasting, calcination, sintering of ores; carbothermal reduction of metal oxide ores, desulfurization of metal sulfide ores, metal oxides, etc.)

4. Drying and roasting of molecular sieve catalytic materials and chemical raw materials
