Beryllium

Beryllium (Be) — 10-Year Trends

As of 2026-09-25 · the last 10 years

Research intensity has remained essentially flat, hovering around 35% of the element’s all-time peak, a level reached in 1964.

Research intensity ran from about 34% of the element's own all-time peak in 2016 to about 35% in 2026 — essentially flat across the window, and the all-time peak (1964) lies before this window. Over the same span its share of research attention across all elements held steady. Among the 118 elements, beryllium has a mid-sized research literature.

The number of papers involving the element rose from about 2,312 in 2016 to about 3,506 in 2025 (1.52x). That is slower than the literature as a whole grew over the same years, so the element lost ground in the wider body of research even as its own count rose.

The research communities driving this literature are distinct and specialized. The largest material community is Beryllium as a Plasma-Facing Material in Fusion Reactors, where beryllium is a minor presence in a much larger community—about 5% of its papers involve beryllium. These studies focus on beryllium's behavior as a first-wall material, particularly regarding hydrogen isotope retention and intermetallic formation under fusion plasma conditions. This community holds about 12% of beryllium's recent research, a steady share compared to the previous period. Key work includes "The new ITER baseline, research plan and open R&D issues" (2025), cited about 55 times, and "Plasma-wall interaction impact of the ITER re-baseline" (2024), cited about 90 times.

A second significant area is Beryllium Sensitization and Chronic Immune Response, where beryllium is one strand of a broader community—about 19% of its papers involve beryllium. This research centers on beryllium-induced sensitization, lymphocyte proliferation assays, and the mechanisms of chronic beryllium disease. It accounts for about 7.5% of the element's recent research, also steady. Notable papers include "Occupational interstitial lung diseases" (2023), cited about 48 times, and "Beryllium contamination and its risk management in terrestrial and aquatic environmental settings" (2023), cited about 56 times.

Third is Beryllium in High-Pressure Warm Dense Matter Physics, where beryllium is a minor presence—about 2% of its papers involve beryllium. These studies examine beryllium under extreme compression, including x-ray Thomson scattering and warm dense matter states relevant to planetary interiors. This community represents about 4.6% of recent research, a steady share. A key paper is "High-Pressure Synthesis of Dirac Materials: Layered van der Waals Bonded BeN4 Polymorph" (2021), cited over 170 times.

Overall, the composition of beryllium research has remained stable, with no single community gaining or losing significant share. The remainder of the literature, comprising other smaller communities, holds about 76% of the element's recent research, also steady. The most-cited paper in the window, "Fluorooxoborates: Beryllium-Free Deep-Ultraviolet Nonlinear Optical Materials without Layered Growth" (2017), cited over 890 times, belongs to the nonlinear optical crystals community, highlighting the element's role in advanced material design.
