About Jingui · Quartz and silica specialists
High-purity quartz, matched to your process.
From high-purity quartz sand and silica powder to precision quartz components, Jingui supports material selection, sample testing and machining to drawing—matching product specifications to your application.
Company profile
Our core team brings twenty-plus years of process experience.
Zhejiang Jingui Technology was founded in 2023, building on a business with a Sino-Japanese joint-venture background. Our core team has more than twenty years of quartz-processing experience in high-purity sand, silica powders and precision quartz components.
Our research and manufacturing teams in Zhejiang, Jiangsu and Shandong work with company-controlled and partner mineral resources. Material development, equipment manufacturing and in-house testing support product supply and processing projects.

- Future
Silicon-based industrial park
Plans for a silicon-based industrial park will bring together mineral resources, research and production through phased development.
Mineral resources
Quality control starts with the raw material.
The team has surveyed more than 2,000 quartz resource sites worldwide, comparing mineral characteristics, impurities and purification potential. Resources in Shaanxi and Myanmar support low-iron, low-radioactivity and high-purity quartz feedstock requirements.
3key mineral resources
Our two Shaanxi resources and Myanmar quartz resources serve different material requirements.
Shaanxi · Low-Iron Resource
With identified reserves of approximately 1.0 million tonnes, this is Jingui's principal low-iron quartz feedstock source. Preparations to obtain exploration rights are at the public-notice stage.
Shaanxi · Low-Radioactivity Resource
Identified reserves of approximately 100,000 tonnes provide low-radioactivity quartz feedstock for applications requiring radiological control. Preparations to obtain exploration rights are at the public-notice stage.
Myanmar
Wholly owned quartz resources with reported reserves of 5 million+ tonnes. Selected ore is used for 6N-grade purification, with delivery planned around regional transport conditions.
Myanmar resource · Site records
Our own resources, managed from the source.
We wholly own quartz resources in Myanmar with reported reserves of 5 million+ tonnes. Ore screening, laboratory analysis and purification trials identify raw material suitable for 6N-grade purification.
Raw-material quality
Our own resources for long-term supply.
Our teams share knowledge of the mineral resources and raw-material test results. Field selection, laboratory evaluation and purification are managed to meet the finished product's requirements.
