Nanobarium titanate powder has good application prospects and domestic enterprises are highly enthusiastic about production.

Nano barium titanate powder refers to barium titanate powder with particle size reaching nanometer level. Nanobarium titanate powder is an important basic material in the electronic ceramic component industry. It has excellent ferroelectric/piezoelectric properties, insulation properties, voltage resistance, high dielectric constant, low dielectric loss, etc., and is widely used in thermal applications. In electronic devices such as sensitive resistors (PTC), optoelectronic devices, multilayer ceramic capacitors (MLCC), and random access memories.

Barium titanate, also known as barium metatitanate, is an ABO3 functional material with a white powder appearance. According to different particle size indicators, barium titanate can be divided into mid-to-low-end particle size products of 400nm and 500nm and high-end particle size products of 50nm, 30nm, and 20nm. Barium titanate preparation processes include hydrothermal method, solid phase synthesis method, sol-gel method, oxalate coprecipitation method, direct precipitation method, etc. Among them, hydrothermal method is the preferred method for preparing high-end nanometer barium titanate powder.

Barium titanate has two crystal forms: cubic phase and tetragonal phase. Tetragonal phase barium titanate has spontaneous polarization phenomenon and its ferroelectric, piezoelectric and thermoelectric properties are more excellent. In recent years, with the advancement of electronic technology, the electronic information industry has developed rapidly. Miniaturization, intelligence, precision, and high performance have become important trends in the development of the electronic components market. Against this background, the market has begun to pay attention to the particle size and activity of barium titanate. , stability, etc. have put forward higher requirements, and the market demand for nanometer barium titanate powder has increased accordingly, especially for tetragonal phase nanometer barium titanate powder.

According to the “2022-2027 China Nanobarium Titanate Powder Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center ” shows that my country’s nano-barium titanate powder manufacturers include Fangxing Technology, China Ceramic Materials, Kaisheng Technology and its subsidiaries Anhui Zhongchuang, Fujian Besike Electronics, etc. Among them, China Ceramic Materials is one of the few in the world that uses hydrothermal methods to produce high-quality nanometer barium titanate powder. One of the companies producing pure nanometer barium titanate powder. The market demand for nano-barium titanate powder is strong. In recent years, there has been high enthusiasm for the construction of domestic nano-barium titanate powder projects, such as Anhui Zhongchuang’s “annual output of 6,000 tons of nano-barium titanate production line project.”

In the international market, nano-barium titanate powder manufacturers include Japan’s Sumitomo, DuPont, Chuo Glass, TDK, Japan’s Sakai Chemical, etc. Compared with international companies, my country’s nano-barium titanate powder companies still have gaps in technology, scale, product performance, etc. Especially in the field of high-end nano-barium titanate powder, domestic market demand still relies on imports.

Industry analysts said that nano-barium titanate powder has the characteristics of high purity, uniform particle size and excellent performance. In recent years, As electronic components develop toward miniaturization and high precision, the market demand for nanobarium titanate powder is rapidly increasing, and the industry has good prospects for future development. At present, my country has the production capacity of nano-barium titanate powder, but the supply of high-end production capacity is insufficient. In the future, the industry will need to continuously upgrade its product structure.
