Ammonium pentaborate tetrahydrate with CAS number 12046-04-7 is a high - quality chemical compound offered at a low price. It has a well - defined chemical formula and specific physical and chemical properties. In terms of its chemical formula, it is (NH₄)₂B₁₀O₁₆·4H₂O. The appearance of this compound is typically a white crystalline powder. It has a certain density and solubility characteristics. Usually, it is moderately soluble in water, which makes it suitable for various aqueous - based applications. The purity of our high - quality product can reach a very high level, which ensures its effectiveness in different industrial and laboratory settings.
Ammonium pentaborate tetrahydrate has a wide range of uses. In the field of flame retardancy, it is an excellent flame - retardant additive. It can be incorporated into plastics, textiles, and other materials to enhance their fire - resistance performance. When added to plastics, it can reduce the flammability of the plastic, making it safer for use in electrical appliances, automotive interiors, and building materials. In the textile industry, it can be used to treat fabrics to make them less likely to catch fire, which is crucial for applications such as curtains, upholstery, and children's clothing.
Another important application is in the field of agriculture. It can be used as a boron fertilizer. Boron is an essential micronutrient for plants, and ammonium pentaborate tetrahydrate can provide a stable and effective source of boron for plant growth. It helps in improving the quality and yield of crops by promoting cell division, pollen germination, and fruit set.
In addition, it is also used in the glass and ceramic industries. It can act as a flux, reducing the melting point of glass and ceramics during the manufacturing process. This helps in energy - saving and improving the quality of the final products, such as glassware and ceramic tiles.
When using ammonium pentaborate tetrahydrate as a flame - retardant additive, it should be added to the polymer matrix during the compounding process. The recommended dosage usually depends on the specific requirements of the final product. For example, in some common plastics, the dosage may range from 5% to 20% by weight. It is important to ensure uniform dispersion of the compound in the polymer to achieve the best flame - retardant effect.
As a boron fertilizer, it can be applied to the soil either by broadcasting or through fertigation systems. The application rate should be determined according to the soil type, crop species, and boron deficiency level. Generally, for most crops, an application rate of 1 - 2 kg per hectare is appropriate.
In the glass and ceramic industries, it is mixed with other raw materials before melting. The proportion of ammonium pentaborate tetrahydrate in the mixture is carefully calculated based on the desired properties of the final glass or ceramic product.
Case 1: Flame - retardant Plastic for Electrical Appliances
A plastic manufacturing company was facing challenges in meeting the fire - safety standards for their electrical appliance housings. They decided to use ammonium pentaborate tetrahydrate as a flame - retardant additive. By adding 15% of the compound to their polypropylene resin during the compounding process, they were able to significantly reduce the flammability of the plastic. The plastic passed the UL 94 V - 0 fire - resistance test, which is a strict standard for electrical applications. This not only improved the safety of their products but also increased their market competitiveness.
Case 2: Boron Fertilizer for Apple Orchards
An apple orchard was experiencing poor fruit set and low yields due to boron deficiency in the soil. The orchard manager applied ammonium pentaborate tetrahydrate at a rate of 1.5 kg per hectare through fertigation. After one growing season, there was a significant improvement in the number of apples per tree and the overall fruit quality. The apples had a better shape, size, and taste, and the yield increased by about 20% compared to the previous year.
Case 3: Flux in Glass Manufacturing
A glass factory was looking to improve the energy efficiency of their melting process and enhance the quality of their glass products. They added ammonium pentaborate tetrahydrate as a flux to their glass batch. By reducing the melting point of the glass, they were able to save about 10% of the energy consumption during the melting process. At the same time, the glass products had fewer defects and
